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.
The climate of the 100 Mile House area is generally dry, with warm summers and cold winters. Precipitations average 420 to 620 mm per year.
