Kamloops' Spring forecast calls for a high chance of skiing in the morning and a likelihood of golf in the afternoon. Kamloops was originally built upon a plain in the Thompson River Valley, but its population has since spread to surrounding highland areas up to 500 metres above the South Thompson River. Kamloops is a tale of two climates: snow lasts about two months longer in the highlands than in the valley. Don’t be fooled if you look outside your downtown Kamloops hotel window in the Winter and see a cold, foggy day: a drive out of the valley may reveal warm, sunny weather perfect for playing in Kamloops's Winter wonderland.
Bring a hat and suntan lotion if you plan to make Kamloops a Summer playground because it has some of the hottest, driest weather of any BC or Canadian city. According to Environment Canada’s historical climate data, between 2000 and 2008 Kamloops’ average temperatures in June, July and August were 18.7 °C, 22.1 °C and 21.5 °C respectively. Kamloops’ warmer climate means that its grasslands are home for rattlesnakes and wildlife that are not found in other parts of BC or Canada. A much warmer than usual average temperature in January 2006 contributed to the Mountain Pine Beetle infestation of Ponderosa Pine forests in the Kamloops area.
