Stormy June soaks northern Ontario, shatters rainfall records

Timmins set a new June rainfall record after storms soaked much of northern Ontario.

It wasn't your imagination—June was a washout in parts of Ontario, with Timmins leading the way, breaking its all-time June rainfall record with a whopping 217.6 mm.

That's more than the previous record of 216.1 mm set in 1984 and nearly three times the city's June rainfall average of 80.4 mm.

In short, Timmins saw nearly three months' worth of rain in just 30 days.

Big downpours, bigger numbers

The rainiest days of the month came near the end. June 27 had the most rainfall with 64.5 mm, followed by June 21 with 51 mm and June 23 with 34.2 mm.
