  Vancouver's climate, one of the mildest and most temperate climates in Canada, is classified as an oceanic climate (Köppen: Cfb) bordering on a warm-summer Mediterranean climate (Köppen: Csb). While the city has the coolest summer average high of all major Canadian metropolitan areas, winters in Greater Vancouver are the fourth-mildest of Canadian cities, after nearby Victoria, Nanaimo and Duncan, all on Vancouver Island.
  
  Vancouver is one of the wettest Canadian cities. However, precipitation varies throughout the metropolitan area. Annual precipitation as measured at Vancouver International Airport in Richmond averages 1,189 mm (46.8 in), compared with 1,588 mm (62.5 in) in the downtown area and 2,044 mm (80.5 in) in North Vancouver. The daily maximum averages 22 °C (72 °F) in July and August, with highs rarely reaching 30 °C (86 °F). The summer months are typically dry, with only one in five days receiving precipitation during July and August. In contrast, most days from November through March record some precipitation.
  
  The highest temperature ever recorded at the airport was 34.4 °C (93.9 °F) set on July 30, 2009, and the highest temperature ever recorded within the city of Vancouver was 35.0 °C (95.0 °F) occurring first on July 31, 1965, again on August 8, 1981, and also on May 29, 1983. The coldest temperature ever recorded in the city was −17.8 °C (0.0 °F) on January 14, 1950 and again on December 29, 1968.
  
  On average, snow falls nine days per year, with three days receiving 5 cm (2.0 in) or more. Average yearly snowfall is 38.1 cm (15.0 in) but typically does not remain on the ground for long.
  
  Vancouver's growing season averages 237 days, from March 18 until November 10. Vancouver's 1981–2010 USDA Plant Hardiness Zone ranges from 8a to 9a depending on elevation and proximity to water.
