To get good insightful answers, how the question is framed matters. I missed an opportunity on Thursday
The humidex is expected to hit 39 at the airport on Tuesday. Humidex advisories are issued at 40 and the city’s heat response goes into effect as well. 39 at the airport usually translates into above 40 for the lower city.
Wednesday’s expected humidex value is 43. At 45, the city pools operate with extended hours.
As of 6 p.m. Monday, the city has not decided to activate the heat plan.
In a special weather statement issued at 5:52 p.m., Environment Canada states a humidex advisory will likely be issued for Hamilton on Tuesday.
Overnight lows will bring some relief in the low 20s or high teens.

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.
