While broiling temperatures broke same-day records in Southern
Ontario and Quebec, filling Toronto’s east end beaches and packing
pools in Montreal, the Prairies enjoyed a respite from the heat
and the coasts continued to feel more like spring than mid-summer.
A high-pressure centre and warm air moved south and east, driving
temperatures at Pearson International Airport, just outside the
nation’s largest city, to 37.5 degrees at 5 p.m. That was good
enough to best the previous record high for July 21 – 35.6 in 1955
– but not enough to top the overall record, 38.3 on Aug. 25, 1948.
Hungary: A woman cools down in Lake Balaton near Tihany 150 km
west of Budapest July 14, 2011. Temperatures reached 38 C in
Hungary that day.
The city did, however, see its warmest-ever morning, with a
highest minimum temperature of 26.6 at 6 a.m. Thursday, edging out
the previous record of record of 26.4, set July 5, 1999.
The trend continued throughout the region, with temperatures of
36.9 in Windsor, 36.4 in London and 36 in Hamilton, all of them
record-breakers. Ottawa, meanwhile, reached 36 and Montreal 35.
As if these temperatures weren’t high enough on their own, the
humidex made it feel as hot as the upper 40s in some places.
As Ontarians blasted their air conditioners, power usage jumped.
In Toronto, for instance, consumption peaked at 4,953 megawatts
shortly before 4 p.m., the highest consumption of the year. It was
lower, however, than the overall record, set in 2006.
The Rogers Centre – which often uses its retractable roof to ward
off inclement weather early in the season – was closed this time
to protect spectators from the heat as they watched the Blue Jays
defeat the Mariners.
The Seattle team probably isn’t used to the heat, as the west
coast has had a cool summer so far. That trend continued Thursday,
with Vancouver hovering around 18 much of the day. It was a
similar story in cloudy St. John’s, which reached a high of 19.
The Prairie provinces, meanwhile, saw wild fluctuation as the hot
air moved eastward. Winnipeg hit 29, down from highs over 30 in
the last few days, while Calgary and Edmonton peaked at just 22.
The trend continued throughout the region, with temperatures of
36.9 in Windsor, 36.4 in London and 36 in Hamilton, all of them
record-breakers. Ottawa, meanwhile, reached 36 and Montreal 35.
