Meteorological Service of Canada Heat Warnings Heat warning criteria were NOT met this month, nor this summer at all! There were no periods when 2+ consecutive days of Tmax were 35°C or warmer and nighttime Tmin were 18°C or warmer.

The chart for Summer 2025 depicts days (red bars) where the daily high (≥ 35°C) and overnight low (≥ 18°C) meet the warning criteria. These criteria are also depicted as red and grey horizontal lines on the chart.
