Weather patterns in British Columbia transitioned from high temperatures and air quality concerns to cooler, wetter conditions in August.

Initially, the region experienced heat spikes, with inland areas reaching up to 33°C. While Victoria remained sunny, the Metro Vancouver Regional District issued air quality warnings due to elevated fine particulate matter and ground-level ozone. 

By late August, a shift in weather patterns brought cooler temperatures and the first rainfall of the month to southern British Columbia. A coastal low-pressure system introduced widespread thunderstorms and potential downpours, providing relief to drought-stricken areas. However, this shift also brought risks of severe weather, including strong winds, large hail, and dry lightning that could increase wildfire risks in the southern Interior.
