Temperatures hit 34 C at the Region of Waterloo International Airport on Tuesday – a rarity both for September and for 2013.

The day smashed the previous record for the hottest Sept. 10 in the area, which was set when temperatures hit 33.3 C on Sept. 10, 1952.

It’s also believed to be the hottest day of summer 2013 locally, narrowly edging out temperatures reached right before a massive storm took hold in mid-July.

For most of the day, temperatures in Waterloo Region were warmer than temperatures in parts of Florida.

Despite the record-breaking heat and high humidity levels, those spending the day outdoors were able to receive some respite thanks to strong winds.

Wednesday is expected to be another hot day, with a high of 30 C and a risk of thunderstorms, but things will cool down from there as a cold front moves in.

Friday’s forecast low temperature stands at 4 C.

A humidex advisory remains in place for southern Ontario.

Environment Canada says “very warm and uncomfortable conditions” will continue into Wednesday.
