Wednesday will be the scorcher of the week with humidex values expected to hit 43. Instability in the air mass caused by daytime heating could generate conditions favourable to lake-breeze fronts that often bring severe downpours to concentrated areas of the city.
The city’s public health department offers advice on keeping cool and coping with the heat on their website here. All outdoor pools are now open.
Thankfully, it’s not 1911 when a heatwave peaked the mercury at a temperature that induces sweat just writing – 39.4°C. How does one manage in that kind of heat, especially before air conditioning.
With that record high in mind, it’s time to get outside and enjoy the heat.
