If you want super serious betting matters, well, we have a whole lot of 2025 NFL season predictions following the schedule release for that. But if you want to bet on something completely out of your control and in the hands of wind patterns and warm fronts, like the Victoria Day in Toronto temperature odds, this is the place to be.

One of our Ontario sports betting sites is offering odds for the max temperature in Canada's largest city on Victoria Day, which is this coming Monday (May 19).

FanDuel Ontario is posting its annual offering for the unofficial start of summer in the Great White North. And sadly, beach umbrellas and inflatable donuts might need to stay in hibernation a little while longer.

🌧️ What Victoria Day in Toronto temperature is the favorite?

It's been peak spring weather weirdness so far this year in Toronto, with a handful of days in the mid-to-low 20s when shorts were located in the back of closets and car windows were rolled down with glee. But there have been plenty of low-to-mid teens days too, leading to sadness among all-weather warrior Grill Dads everywhere who are desperate for a sprinkle of sunshine.

More of the same yo-yo weather seems to be in store for the May long weekend, with peak chilliness coming during the day in question here.

As The Weather Network notes, the temperature in Toronto is expected to abruptly spike on Friday, resulting in a balmy 26 degrees. That's well above the average daytime high in Toronto during May of 17 degrees, according to City News.

The rising temperature is prompting a sacred spring day for Toronto Blue Jays fans, with the Rogers Centre roof opening for the first time this season.

The relative warmth is forecasted to subside, but it still sticks around to some degree on Saturday, with a high of 19. However, a quick course correction is in store beginning Sunday night, when anyone on a late-night walk might even break out the winter gloves.

The mercury plummets to just 5 degrees overnight between Sunday and Monday, resulting in a high of just 13 forecasted for Victoria Day.

That's why 17 or lower is the overwhelming favorite by the odds, with the -210 price leading to an implied probability of 67.74%, and a $10 winning bet translating to a profit of only $4.76.

If you're a dedicated weather betting enthusiast (we meet weekly), FanDuel Ontario is also featuring odds for when the first day at or above 30 degrees will occur in Toronto this year. May 15-30 is the favorite at +125, and June 1-14 isn't far behind at +195.
