The humidex isn’t going away any time soon, but this is exactly what a normal July day looks like:
Expect a high of 27 C during the day, with a humidex of 32 C and a UV index of 7, or high. At night, a low of 19 C. The average high for July 23 is 26.6 C, according to Environment Canada.

A solar storm in May provided a glorious light show to Montrealers and other people in southern Quebec. It did not affect the electrical grid, said Pascal Poinlane, a spokesperson for Hydro-Québec. In 1989, a geomagnetic storm caused a nine-hour outage on Hydro-Québec’s transmission networks.
The phenomenon, which is impossible to predict, is completely benign on the Earth’s surface, because all the energy is absorbed in the upper atmosphere, Paul Charbonneau, a professor specializing in solar physics at the Université de Montréal, told The Gazette in May.
That’s cool. We’ll wait.
