The Climate Statistics of the Thompson-Nicola Region 

The Thompson-Nicola region is situated in the Interior Plateau and experiences a dry and more continental climate because the Coastal Mountains act as a barrier to the westerly flow of moist air. Our summers are typically warm and dry, and so are our winters, making working outdoors comfortable regardless of season.

The Thompson valley experiences BC's hottest summers, with temperatures often in the 30°s C (86°-102°F), and occasionally rising above 40°C (104°F). Kamloops averages 28°C (82°F) in July and -1°C (30°F) in January with just 279 mm (11 inches) of annual precipitation. Ashcroft, Cache Creek and Lytton tend to be hotter and drier, and Lytton is branded "Canada's Hot Spot".

The Nicola valley, being directly east of the Coastal Mountains, is also warm and dry, and experiences little snow in the winter, especially in the grasslands. However, winds may cause snow drifts. In the summer, it's lovely, and warm and dry with gentle breezes.
