Other weather tidbits from past Halloweens

While Nov. 21, 2007 saw the Great Toronto Area's (GTA) high only reach 9 C., just a few weeks earlier, on Oct. 31, trick-or-treaters were delighted with temperatures as high as 18 C.

If you wanted to know the record for the hottest GTA Halloween, that tally is a mild 22.8 C, set in 1971. The normal daytime for that time of year is 10 C.

Montreal had a very wet Halloween in 2019, with forecasts putting projected totals as high as 50+ mm. The city and surrounding regions were also faced with blustery wind gusts that reached up to 90 km/h. In fact, the conditions were rough enough to postpone the day's planned activities, moving them to Friday, Nov. 1.
