On a normal July day the thermometer tops out near 23.7°C. Counting rain and snow together, it is drier than 76% of Canadian towns. Precipitation peaks in July and eases off in February. Plan for rain or snow on about 83 days a year, the days with 1 mm or more.
Snow Lake has no ECCC normals station nearby: the figures come from Flin Flon, 109 km west, so read them as the wider area’s climate.
