How does lake effect affect the hourly forecast?

Whitby sits along Lake Ontario, so cold winds can suddenly bring flurries even when the regional forecast is clear. The hourly table above catches those small-scale changes better than a daily prediction. If you see a north wind pick up, expect a quick drop in visibility and temperature within the next hour or two.

Is the hourly forecast reliable for an outdoor event?

Yes, within a few hours. Environment Canada updates its hourly table at least every three hours, so it’s the best bet for timing a park visit or a commute. Check again an hour before your event.
