Weather Trivia

Did you know?
Sioux Lookout has one of the highest summer rainfall totals in Northwestern Ontario due to its unique geography that funnels moist air masses from the Prairies and the Great Lakes. June is statistically the wettest month, and wildfire seasons often overlap with these storm cycles—leading to both air quality alerts and flood advisories.
