Stump Lake weather is typically dry and sunny in summer, with daytime highs near 25 °C and cool nights. Winters are cold with light snowfall, and strong winds can come up across the lake at any time of year. Check the live forecast above for current conditions.
What makes Stump Lake’s weather different?
Stump Lake sits in a semi-arid valley east of Kamloops, which means it gets less rain than the surrounding mountains. Summer afternoons often see a breeze from the south, and winter inversions can trap cold air in the basin. This produces clear skies but chilly mornings, especially from November through February.
For comparison, Kamloops weather tends to be a few degrees warmer, while Tunkwa Lake weather typically sees more cloud and precipitation at higher elevation.
Is Stump Lake good for fishing in this weather?
Yes. The lake is a popular rainbow trout fishery. In spring and fall, cooler weather keeps fish active near the surface. Summer heat pushes them deeper, so morning or evening is best. Wind can make boat handling tricky, so check the live forecast above before launching. Nearby Paul Lake weather and Roche Lake weather follow similar patterns but offer different access points.
Does Stump Lake freeze over in winter?
Yes, the lake typically freezes from December to March. Ice thickness varies, but it is generally safe for ice fishing. Always test thickness yourself and check the forecast for warm spells that weaken the ice.
When is the best time to visit Stump Lake?
Late May through September offers the most reliable warm weather for camping and boating. September is quieter and still warm during the day, making it a favourite for Stump Lake fishing trips.
How windy does it get at Stump Lake?
Afternoons from April to June can bring sustained winds of 20–30 km/h, with stronger gusts. The lake is exposed, so small boats should stay alert. Morning hours are generally calmest.
