Fog, Showers, and Humid Days Ahead as Toronto Settles into a Classic Spring Stretch

TORONTO – WEATHER REPORT – Toronto is waking up to a wet and muggy Wednesday morning as light rain and thick humidity blanket the city.

If you’re hoping for consistent patio weather—you might need to wait until next week.

What to Wear for Toronto’s Humid and Wet Days

It’s an umbrella-in-the-bag kind of week. Today calls for a light raincoat and waterproof footwear, while tomorrow and Friday will feel muggy enough for short sleeves—but with a chance of sudden downpours, keeping a light jacket and rain gear handy is wise. Foggy mornings midweek will also mean cautious commutes are a must.
