June continued the nearly year-long trend of being warmer than usual. The 20th century norm was 14.5C; this year it was 16.3C or 1.8C higher. The coolest night was the 11th at 4.8C and the hottest day was the 18th at 29.6C.
Subjectively I’m not sure it felt warmer than usual because the mercury fluctuated so much. Apart from four days in the middle of the month when we got caught under the “heat dome” that affected much of the Province, there was no consistency. In fact, if it were not for those few days in the upper twenties the month would have been ‘normal”. The heat dome and humidity resulted in softened railway tracks in the GTA, along with record setting humidex values of 45C in Chapleau and 44C in Toronto.
It was also cloudier than usual so we got about 20% less sunshine.
Rainfall, on the other hand, was abundant. The wet stuff amounted to 100mm. which wasn’t a record but was well over the average of the last twenty-five years. We got at least a little rain on half the days of the month, and a lot – 35mm.- on the 22nd with a further 11mm. the next day.
(As an aside, I like to check my figures against the Environment Canada station at Tobermory Airport – but the data is missing for the several wettest days!)
The Province generally was not quite as wet as we were, though most of the south was much wetter than usual. To our west, Sault Ste Marie got 212% of normal and it was the tail-end of that front that gave us the extra moisture.
July has started out a bit cool but is forecast to be close the normal.
