Vancouver’s climate is known for being among the mildest and most temperate in Canada, defined by its oceanic classification (Köppen Cfb), with influences from a warm-summer Mediterranean climate (Csb). Nestled on the country’s west coast, Vancouver enjoys cooler summers and warmer winters compared to other major Canadian metropolitan areas. In fact, winters in Greater Vancouver are only surpassed in mildness by nearby Vancouver Island cities such as Victoria, Nanaimo, and Duncan.
Rain is a defining feature of Vancouver’s weather. Though it ranks as one of Canada’s wettest cities, rainfall levels vary significantly across the region. Vancouver International Airport in Richmond records an annual average of 1,189 mm (46.8 inches) of precipitation. In contrast, downtown Vancouver sees about 1,588 mm (62.5 inches), while North Vancouver—closer to the mountains—receives a much higher 2,044 mm (80.5 inches) annually.
Despite its soggy reputation, summer in Vancouver is typically dry and pleasant. July and August bring daily average highs of 22°C (72°F), and only 20% of days during these months receive any measurable rain. It is rare for summer temperatures to climb above 30°C (86°F). The hottest temperature on record at the airport was 34.4°C (93.9°F) on July 30, 2009, while the highest ever in the city itself was 35.0°C (95.0°F), reached on three separate occasions: July 31, 1965, August 8, 1981, and May 29, 1983.
Winter temperatures remain relatively moderate, with Vancouver ranking among the warmest large cities in Canada during the colder months. The coldest temperature ever recorded in the city was −17.8°C (0.0°F), occurring on January 14, 1950, and again on December 29, 1968. Snowfall is light and infrequent, averaging 38.1 cm (15 inches) annually, with snow typically melting quickly due to the mild conditions. On average, snow falls on nine days per year, with only three days accumulating 5 cm (2 inches) or more.
The city’s growing season is among the longest in the country, averaging 237 days, beginning around March 18 and extending through November 10. USDA Plant Hardiness Zones in Vancouver range from 8a to 9a, depending on elevation and distance from the coastline—conditions that support a wide variety of plant life year-round.
Vancouver’s distinctive climate, characterized by wet, temperate winters and warm, dry summers, plays a central role in shaping the region’s natural beauty, biodiversity, and lifestyle. It remains a standout among Canadian cities, offering residents a climate that is both gentle and green, especially compared to the harsher weather experienced in much of the country.
