Toronto weather record broken by wild summer of thunderstorms
If you felt like Toronto saw an unusually high number of thunderstorms this summer, you’re right.
In fact, the city surpassed its record-high for summer days with thunderstorms this year, recording 21 days where the skies lit up with lightning through the season.
This year marks the first time that over 20 thunderstorm days were recorded during any summer at Toronto Pearson Airport in the 68 years since record-keeping began.
The latest record overtook the previous title-holder of summer 1986, when the city recorded 19 thunderstorm days. Toronto fell just short of tying this record in 2019, with 18 days of thunder and lightning.
To better grasp just how much high-voltage weather Toronto experienced over the summer, the median average from 1991 to 2020 was just 11 thunderstorm days.
The record-low was in 1972 when just four thunderstorm days were recorded all summer.
It sure seemed like the city was getting more than the average amount of thunderstorms this summer, but 20 days is quite a bit.
Summer lasts for just 92 days, meaning we spent almost 22 per cent of the season under thunderstorm warnings, versus the mean average of just below 12 per cent.
