A Glorious Saturday in the Six Sets the Tone for a Mixed-Bag Weekend
TORONTO, ON – May 10, 2025 – Grab those sunglasses and maybe a windbreaker—Toronto is waking up under mainly sunny skies and a fresh morning breeze, with temperatures at a crisp 5.2°C as of 6:00 AM at Pearson International. With a barometric pressure of 101.8 kPa and a falling tendency, we’re looking at a high of 22°C today, powered by clear skies and an increasingly gusty north wind expected to hit 20 km/h later this afternoon. Humidity sits comfortably at 50%, keeping the air feeling refreshingly spring-like.
Sunday Brings a Cool-Down, But Sunshine Stays Strong

Sunday eases into cooler territory with a high of 14°C and continued sunshine—perfect weather for a morning stroll or a patio coffee. Winds will calm to light by mid-morning after an early northeast breeze of 20 km/h.

Monday Heats Up Before Tuesday’s Clouds Roll In
As we kick off the workweek on Monday, sunshine makes another strong showing with a high of 23°C—definitely a shorts-and-t-shirt kind of day. But don’t get too used to it. By Monday night, cloud cover will begin to build with a low of 12°C.
Tuesday ushers in a 30 percent chance of showers and a more overcast tone, with temperatures cooling slightly to a high of 19°C. The chance of showers increases slightly into Tuesday night with a 40 percent chance and a low of 13°C.
What to Wear
Layer up this morning but prepare to shed some layers by mid-afternoon. A windbreaker is a good idea today with that stiffening north breeze, and sunscreen is a must with the UV index sitting at a very high 8. Sunday calls for a light jacket, while Monday might tempt you back into summer gear.
