Toronto’s weather is largely regulated by the Great Lakes which are so massive that they create their own micro-climate. Unfortunately, the effect isn’t very pleasant in terms of comfort. There are those who would argue that Toronto offers the worst weather on the planet, but don’t let that put you off.
Summers in Toronto are nothing to cheer about unless you enjoy sweating. Although maximum summer temperatures tend to average around 30℃ in August, Lake Ontario creates so much humidity that it often feels 10°C hotter, a factor which many people find extremely uncomfortable.
Another unfortunate phenomenon in Toronto is the summer smog. Although air quality has improved in recent years, the smog that hovers over the city in the summer is often dangerous enough to receive health alerts.
Not to be upstaged by summer conditions, the winters in Toronto can be miserable. Again, the Great Lakes are the culprits, creating bitter cold weather with some truly howling snowstorms mixed in throughout the season. Temperature averages just below freezing point and snow sticks around all winter long. To make matters worse, the sun doesn’t shine enough to give you much relief.
In contrast, autumn is the one time of year when you can find reliably good conditions. The temperatures are pleasant, the skies are blue and all those pesky bugs are gone.
Toronto’s high season runs from April to October, and hotel rates will be at their highest during this time. However, the summer is when most of the fun festivals, concerts and other outdoor events take place, so it’s no surprise that the city is visited by many tourists.
If you can handle freezing cold temperatures and grey skies, then you can take advantage of Toronto’s low season. Hotels often drop their rates by half during the winter, and you can be sure to avoid the crowds. A more pleasant time to visit is the autumn, especially late September and October. The leaves change their color, the weather is fine and the city is mainly full of locals.
