Climate of Vancouver

General Climate Characteristics

The climatology of Vancouver applies broadly to the Greater Vancouver region, though its coastal location and mountainous terrain create distinct microclimates. The Alaska Current, originating from the North Pacific, serves as a moderating influence, tempering both winter cold and summer heat. This oceanic influence results in one of the warmest average annual temperatures among major Canadian cities, at 11.0 °C downtown and 10.4 °C at Vancouver International Airport. The region's high latitude of 49 degrees north contributes to very short days in winter, with sunsets as early as 4:10 PM and sunrises as late as 8:12 AM. Vancouver averages less sunshine in winter than any other major Canadian city, with over 70 percent of short winter days being completely cloudy at the airport. The interaction between sea breezes and the North Shore Mountains leads to increased cloud development and significantly higher precipitation on mountain slopes compared to sea-level areas. Predicting precipitation is particularly complex due to the topography, with snowfall being especially problematic for forecasters because temperatures often remain close to freezing during snow events.

Temperature Patterns and Extremes

Vancouver's temperatures are notably mild for its latitude, with a growing season averaging 221 days from March 29 to November 5, which is 72 days longer than Toronto's. The city is within USDA plant hardiness zone 8, similar to coastal European cities like Amsterdam and London, and it sustains hardy subtropical plants like the Windmill Palm. Despite the general mildness, the region is subject to occasional cold outbreaks known as Arctic outflows or squamish winds, which occur one to three times per winter on average. These events channel cold continental air down the Fraser Valley, sometimes lasting a week or more. The coldest month on record at Vancouver International Airport was January 1950, with an average daily low of -9.7 °C and a daily average of -6.3 °C. The coldest temperature ever recorded in the city itself was -18.3 °C on December 29, 1968, while across Metro Vancouver, the record low is -23.3 °C from Pitt Meadows in January 1969. Summer temperatures show significant variation across the region, with inland areas of the Fraser Valley often being 5 to 10 degrees Celsius warmer than ocean-tempered coastal zones when onshore breezes are present. Conversely, winter temperatures tend to be a couple of degrees cooler inland than on the coast.

Recent years have seen record-breaking heat events linked to broader climate trends. In June 2021, West Vancouver recorded an extreme high of 40.6 °C and Pitt Meadows reached 41.4 °C. Forecasts indicate that the period from 2026 to 2030 will likely be the hottest five-year period on record for Canada. Environment and Climate Change Canada modelling predicts 2026 global mean temperatures will be 1.35 °C to 1.53 °C above pre-industrial levels, with a 12 percent chance of exceeding the 1.5 °C Paris Agreement threshold. This warming trend is part of a pattern where Canada is heating at more than twice the global rate. The record warm month of August 2022 saw an average monthly mean temperature of 21.0 °C at Vancouver Harbour and 21.5 °C at Pitt Meadows. Other notable records include the warmest monthly average daily minimum of 16.4 °C at Vancouver Harbour in August 2022 and the record high dew point of 23.0 °C at the airport on July 29, 2022.

Rainfall and Seasonal Precipitation

Vancouver is Canada's third most rainy city, experiencing an average of 169 rainy days per year. Precipitation is highly variable due to topography, with a general rule that it increases by about 100 mm for every 100 metre rise in elevation. As a result, annual rainfall at Vancouver Airport is 1,189 mm, while in North Vancouver, at the base of Grouse Mountain, it more than doubles to 2,477 mm. The city has a distinct seasonal precipitation pattern, with summers being notably dry. July is historically the driest month, and in July 2013, Vancouver Airport recorded no rainfall for the entire month for the first time in history. Many other Julys have seen less than 1 mm of rain, including July 2021 which received no rain at all. The dry summers mean Vancouver is one of the driest Canadian cities during that season, but this changes dramatically from fall through mid-spring. The rest of the year is dominated by low-pressure systems bringing frequent, cool, and showery weather. Thunderstorms are rare, averaging only about 6.1 days per year, because the city lacks a hot summer that would fuel convective storms. The grass-cutting season often begins in March and can continue through October, though dry summers may mean lawns go uncut for weeks.

The autumn of 2006 provided a stark example of extreme rainfall, when 25.5 cm fell in the first 16 days of November, breaking the previous record. This heavy rain washed sediment into the city's reservoirs, leading to advisories for businesses to stop serving beverages made with tap water. Such events underscore the vulnerability of the region's water supply to intense precipitation. Environment Canada has warned that the coast should expect above-average precipitation in the coming fall seasons as part of changing climate patterns.

Snowfall and Winter Weather

Contrary to a common misconception, Vancouver does receive snow, with traceable snow observed every year at the airport. The year 2015 marked an exception with no measurable snow, only a trace recorded on December 17. Measurable snow is infrequent. Environment Canada ranks Vancouver third for lowest snowfall among 100 major Canadian cities, with an annual average of only 8.7 days with snowfall above 0.2 cm. However, the city's coastal climate also places it 59th for 'most huge snowfall days', above Calgary and Toronto, as it averages 0.13 days annually with accumulations above 25 cm. Snow tends to be wet and often leads to icy conditions as temperatures fluctuate around freezing. While generally low, snowfall can be extreme in certain years. The snowiest year on record was 1971, when Vancouver Airport received 242.6 cm, with 120 cm falling in January alone. The greatest snow depth reported was 61 cm on January 15, 1971. Snowfall exceeding 100 cm occurred twice in the 1990s, and a notable event in November 2006 dropped 30 to 60 cm across the region in 24 hours.

Even modest snowfalls can cause significant disruption, including school closures and traffic problems, as the city's infrastructure is not optimized for frequent snow removal. The City budgets $400,000 annually for equipment maintenance and training, but actual removal costs come from contingency funds and vary widely, from $1.1 million in 1998 to $0 in 2001. The probability of a White Christmas in Vancouver has increased, with Environment and Climate Change Canada estimating a 20 percent chance as of 2011, up from 11 percent. The city experienced White Christmases in 2007, 2008, and 1998. In 2008, over 60 cm of snow was on the ground, with 41 cm measured on Christmas Day, making it Canada's whitest Christmas that year. Despite higher frequency during certain periods, annual winter snowfall has decreased over the last 20 years.

Severe Weather Events and Storms

While gales are uncommon in autumn, Vancouver's history includes several significant wind storms. Major storms in October 1934 and October 1962, the latter being the remnant of Typhoon Freda, caused extensive damage to the forests of Stanley Park. The 1962 storm levelled a 2.4-hectare tract of forest, which is now the site of the park's miniature railroad. More recently, the Hanukkah Eve windstorm of December 15, 2006 swept through Greater Vancouver with winds reaching 125 km/h. It damaged or uprooted over 5,000 trees in Stanley Park, caused mudslides that destroyed a section of the seawall, and resulted in provincial insured damages expected to reach 40 million dollars. Repairs to Stanley Park alone were expected to cost 9 million dollars. The November 2006 period also brought severe weather, including 25.5 cm of rain in the first 16 days, which washed sediment into reservoirs and prompted water advisories. This was followed by significant snowfall, with 28 cm recorded at the airport from November 25 to 27, and a temperature drop to -12 °C on November 28. An additional 10 cm of snow fell on November 29, leading to power outages in Surrey and Langley and the closure of public institutions. Such compound events highlight the region's vulnerability to severe weather.

Blizzards are extremely rare in Vancouver, but heavy snowfall events are more common. One such event in 1996 resulted in over 60 cm of snow and was responsible for millions of dollars in damage. The increasing frequency of these events is linked to climate change, with scientists warning that wildfires and severe weather would become more frequent and intense. The province's deadly 2021 heat dome and catastrophic flooding are cited as examples of this trend.

Climate Change and Future Projections

Vancouver is already experiencing the impacts of climate change through more intense and frequent extreme weather events. Scientists have long warned that events like heat waves and severe storms would become more common. The United Nations Intergovernmental Panel on Climate Change has issued a code red for humanity, noting the window to limit warming to 1.5 °C above pre-industrial times is closing. Global climate data shows 2023, 2024, and 2025 were consecutively the warmest years on record, with 2024 breaching the 1.5 °C threshold at 1.55 °C. Human activities have raised atmospheric carbon dioxide concentrations by 50 percent in less than 200 years, reaching 432.34 parts per million as of June 5, 2026. Forecasts indicate that 2026 could be among the hottest years globally, with Environment and Climate Change Canada noting that the period from 2026 to 2030 will likely be the hottest five-year period on record. The agency stresses that taking action to prepare for these impacts is an economic imperative, and building climate resilience is essential to protecting Canadian communities.

Climate phenomena like El Niño, described as a 'global furnace,' and La Niña, akin to 'global air conditioning,' are major drivers of year-to-year temperature variability atop the long-term warming trend. The NOAA has indicated an El Niño event could grow to 'historic strength' in 2026, increasing the risk of higher temperatures. Early-season heat events are also projected, with forecasts for May 2026 suggesting temperatures 5 to 15 degrees Celsius above normal. Drought is a recurring climate risk caused by combinations of low snow accumulation, hot and dry weather, or a delay in rainfall. Following an abnormally warm winter in 2025 to 2026 that shattered records, forecasts suggest the coming winter could also be unusual. These projections underscore the need for informed planning using reliable climate data to mitigate risks associated with drought, extreme heat, and changing precipitation patterns in the Vancouver region.

Regional Climate Variations and Records

Greater Vancouver's climate is not uniform, with significant differences in temperature and precipitation records across its municipalities. At Vancouver International Airport, the record high is 34.4 °C, set on July 30, 2009, alongside a record high daily minimum of 22.4 °C the same day. Inland and higher elevation areas routinely experience more extreme temperatures. For instance, Pitt Meadows recorded a high of 41.4 °C in June 2021, and West Vancouver hit 40.6 °C the same day. White Rock recorded 38.5 °C that same period. The record for the warmest month also varies by location. August 2022 was the warmest month on record at Vancouver Harbour, with a mean temperature of 21.0 °C, while at Pitt Meadows, August 2022 saw the warmest average daily maximum at 28.0 °C. Other notable records include the warmest monthly average daily minimum of 15.8 °C at Pitt Meadows in August 2025, and the most humid month at the airport being August 2022 with an average dew point of 16.5 °C. Precipitation follows a similar pattern of local variation. The complex topography means that predicting snow is particularly challenging for meteorologists, as temperatures often hover near freezing during snow events. These microclimates mean that weather conditions can change dramatically over short distances within the metropolitan area, with the North Shore consistently receiving more rain and experiencing different cloud cover than the airport.

Daylight and Seasonal Transitions

Vancouver's relatively high latitude significantly influences its daylight hours throughout the year. In the depths of winter, the short days see less than eight hours between sunset and sunrise. The combination of this natural phenomenon and the observance of daylight saving time means that in summer, civil twilight can last past 10 PM, creating long, bright evenings. The arrival of spring is often first noticed in late February with slightly milder temperatures and the return of flowering perennials. It is not uncommon for cherry trees to begin blooming later in February, as was seen prominently during the 2010 Winter Olympics. With snow being an infrequent occurrence over a typically mild winter, many cold hardy flowers remain in bloom and are common in gardens and office exteriors throughout the season. However, the transition seasons are not consistently gentle. Spring and autumn weather is usually showery, cool, and overcast, and some years can bring late spring snowstorms and cold temperatures. This variability makes the long growing season possible but also punctuates it with unpredictable weather shifts.

Questions about Climate of Vancouver

Does it snow in Vancouver?

Yes, it does snow in Vancouver, contrary to a common myth. Traceable snow has been observed every year at Vancouver International Airport. However, measurable snow is infrequent, with the city averaging only 8.7 days per year with snowfall above 0.2 cm. Snow tends to be wet and can cause significant disruption to traffic and schools, even in small amounts, as the city is not equipped for frequent snow removal.

What is the hottest temperature ever recorded in Vancouver?

The hottest temperature ever recorded in the Greater Vancouver area was 41.4 °C in Pitt Meadows on June 28, 2021. Within the City of Vancouver proper, the record high at the harbour station is 34.9 °C, set on July 29, 2009. These extreme highs are part of a broader trend of increasing temperatures linked to climate change. Forecasts suggest the period from 2026 to 2030 could be the hottest five-year stretch in Canada's recorded history.

Why does it rain so much in Vancouver?

Vancouver's high rainfall is due to its coastal location and mountainous terrain. The city is exposed to moisture-laden Pacific storms, especially from October through March. The North Shore Mountains force this moist air to rise, cool, and condense, significantly increasing rainfall on their slopes. For every 100 metre rise in elevation, precipitation increases by about 100 mm. This is why North Vancouver receives over twice the annual rainfall measured at the sea-level Vancouver Airport.

How does climate change affect Vancouver's weather?

Climate change is making extreme weather events in Vancouver more intense and frequent. This includes hotter heat waves, like the 2021 event that shattered records, and more severe storms. Scientists warn that phenomena such as droughts and flooding will become more common. Global forecasts indicate 2026 could be exceptionally hot, with a chance of exceeding key international climate thresholds. Vancouver must prepare for these impacts, as building climate resilience is seen as an economic and social imperative.

What are Vancouver's summers like?

Vancouver's summers are typically warm and dry, with July and August being the sunniest months. The city is one of the driest in Canada during summer, and it is not uncommon for several weeks to pass without rain. July is historically the driest month, with some years recording virtually no rainfall. Summer temperatures are moderated by the ocean, but inland areas of the Fraser Valley can be 5 to 10 degrees Celsius warmer than the coast. The growing season averages 221 days, the longest of any major Canadian city.

What is the chance of a White Christmas in Vancouver?

According to Environment and Climate Change Canada data from 2011, Vancouver has a 20 percent chance of a White Christmas, which is up from an earlier estimate of 11 percent. The city experienced White Christmases in 2007, 2008, and 1998. In 2008, over 60 cm of snow was on the ground after a series of storms, giving Vancouver the title for Canada's whitest Christmas that year. While annual winter snowfall has decreased over the last two decades, certain periods can still bring significant snow.
