As the weather heats up, so do the lakes. Ontario lake temperatures have soared over the last month, meaning that swimming and other water activities are definitely in the forecast for this long weekend. So grab your bathing suits, canoes, and floaties and head to the lake, because it's the perfect time to take advantage!

In its "floatie forecast," The Weather Network reports that lake temperatures offer ideal conditions for all water-related activities this Civic Holiday long weekend, after a dramatic rise as compared to the Canada Day long weekend, when lakes across the province were chilly.

In fact, on average, the Great Lakes have seen temperatures rise by a considerable 5.4° Celsius since the Canada Day long weekend.

However, Lake Huron has made a mockery of that figure and seen the biggest temperature increase, almost doubling from only 10°C at the beginning of July to 19°C at the close of the month.

And, according to The Weather Network, Lake of Bays in Muskoka has a lake temperature of a balmy 26°C at the surface level. The popular spot is less than 200km north of Toronto.

"It takes water a long time to heat and cool, but most areas have seen a gradual increase with our recent heatwave and warming temperatures through July," said meteorologist Jaclyn Whittal in the report.

Though Ontario doesn't have the warmest lake in the country right now -  that honour goes to Osoyoos, B.C. - the temperatures are certainly better than before and will make for a far more pleasurable swim session!

If the good weather holds up and these high temperatures remain, this long weekend is shaping up to be a gorgeous few days at lakes across the province.
