Climate and Topography
The generally temperate climate of British Columbia, varying from marine to continental, is determined by prevailing westerly winds, the warm Pacific Ocean, mountainous topography and the province's northerly location. The coastal region has abundant rainfall and mild temperatures associated with a marine climate, and enjoys Canada's longest frost-free periods. In the interior, the climate is continental in nature with the southern interior having the province's driest and warmest climate.
British Columbia has a rich variety of habitats, including forests, grasslands, meadows, wetlands, rivers and inter-tidal and sub-tidal zones. They support the greatest diversity of plants and mammals of any province in Canada.
With an average maximum summer temperature in excess of 26ºC, and an average minimum winter temperature of about -8ºC, the Thompson-Nicola Region tends to experience relatively mild winters (by Canadian standards). Growing seasons average approximately five months in duration, with at least 120 frost-free days a year. Winter snowfall in the lower elevations is limited, while rainfall is more common in the higher elevations during the summer months. The region has one of the highest agricultural production levels in the province, indicative of its favourable climate.
