Clouds Rolling In With Showers This Afternoon – Warmer Days Ahead
A Calm, Cool Morning to Start the Day
Toronto, ON – Wednesday, May 28, 2025: The city wakes up to a partly cloudy sky and cool 10.5°C temperatures at 6:00 AM, as observed at Toronto Pearson International Airport. There’s a touch of crispness in the air, with humidity at 74%, and a gentle northeast breeze blowing at 10 km/h. The dew point is 6.0°C, making for a fresh-feeling morning, and visibility is a clear 24 km. Pressure sits at 102.2 kPa but falling, suggesting today’s weather will take a bit of a turn.
Clouds Thicken and Rain Arrives by Afternoon
Today’s forecast features a mix of sun and cloud early on, but expect conditions to become overcast by late morning, with a 60% chance of showers in the afternoon. Temperatures will climb modestly to a high of 17°C, and with a UV index of 7, sun protection is still important during those brief sunny breaks.
Winds will shift to the southeast at 20 km/h, bringing in moisture from the lake and likely adding a cool edge to the air near the waterfront.
Wet and Foggy Tonight
Showers will continue tonight, and as temperatures fall to a low of 12°C, fog patches will develop after midnight. It’s going to be a damp, misty evening — ideal for tea and blankets, less ideal for patio plans. Winds will calm as the evening progresses.
Thursday: Fog Clears, Showers Linger
On Thursday, expect more cloud cover with a 60% chance of showers or drizzle, especially through the morning. Fog patches will dissipate by mid-morning, and winds will shift from southeast to west at 30 km/h, helping to clear things out a bit. The temperature will climb to 19°C, and the UV index remains high at 6, so prepare for intermittent brightness between the greyness.
Friday and Saturday: A Brighter Outlook
Friday is shaping up to be a more classic late-spring day with a mix of sun and cloud and a high of 21°C, followed by cloudy periods and a 40% chance of showers overnight with a low of 11°C.
Saturday sees a bit of a cooldown, with a high of 17°C and more mixed skies, but Saturday night clears up, dipping to a crisp low of 8°C — just in time for any evening plans that involve a clear sky.
What to Wear?
Mornings still call for a light jacket, but if you’re heading out later today, bring an umbrella and something waterproof. It may not be a full-on downpour, but the afternoon showers could surprise you. Layers are your best bet with temperature swings and moisture in the mix.
Historic Temperatures for May 28
Toronto’s record high for this date is 31.1°C, while the record low is a chilly 4.4°C. With a forecast high of 17°C, we’re right in the middle — mild and manageable, if a bit damp.
Toronto Weather Trivia
Toronto’s lake breeze effect can swing temperatures by as much as 10°C between downtown and the northern suburbs, especially in spring. So if you’re on the waterfront and wondering why it feels more like 12°C than 17°C — now you know who to blame (Lake Ontario).
