Toronto Weather Forecast – Intermittent Showers and Bright Breaks with a Warmer Week Ahead
A Breezy and Changeable Saturday
Toronto, ON – Saturday, May 24, 2025: Toronto wakes up under light rainshowers and a cool breeze this morning, with temperatures sitting at 9.2°C at 6:00 AM at Pearson International Airport. The humidity is at 82%, and a northwest wind at 20 km/h is gusting to 40 — enough to send your umbrella into orbit if you’re not careful. Pressure is rising at 101.5 kPa, a sign that some improvements in the sky are in store today. Visibility remains strong at 24 km, so while it may be damp, it’s not dreary.
Today’s forecast calls for a mix of sun and cloud with a 30% chance of spotty showers throughout the day. While most of the day should stay dry, don’t be shocked if a stray sprinkle catches you during your coffee run. The high will reach 16°C, and with a UV index of 6, the sunshine that does break through will be strong — so don’t skimp on SPF if you’re outdoors between sun and showers.
Clear Skies and Calmer Winds Tonight
Tonight, skies will clear, and winds from the northwest will ease after midnight. The overnight low dips to 8°C, making it a great night for an evening stroll, patio lounging, or catching up on some stargazing.
Sunday: More Sunshine, But Keep an Eye on the Sky
Sunday keeps things lively with a mix of sun and cloud and a 40% chance of showers in the afternoon. There’s even a risk of a thunderstorm, so if you’re heading to a park or patio, keep one eye on the radar. Winds will pick up again from the northwest at 20 km/h, and the high stays near 16°C. The UV index climbs to 7, so sun safety remains a top priority despite the chance of clouds and storms. Sunday night brings cloudy periods and a low of 8°C.
Monday: A Turn for the Better
Monday kicks off the workweek on a sunny note, with a mix of sun and cloud and a high of 20°C — finally tipping us into warmer, more seasonable spring territory. Monday night remains partly cloudy with a mild low of 10°C, a comfortable close to what’s shaping up to be a much more pleasant week.
What to Wear?
Today’s weather wardrobe includes a light jacket, windproof umbrella (or deep pocket for dodging quick sprinkles), and some layered clothing for changing conditions. Sunglasses will come in handy between the clouds, and sunscreen is a must with that UV index pushing 6. For Sunday, you might want to pack a rain jacket — and keep the barbecue covered just in case.
Historic Temperatures for May 24
Toronto has seen some dramatic swings on this date in years past — with a record high of 31.4°C and a record low of 2.2°C. Today’s 16°C high sits comfortably in the middle — a classic late-May “bit-of-everything” kind of day.
Toronto Weather Trivia
Did you know Toronto has more days with measurable sunshine than many people expect? Despite our moody spring skies, the city averages over 300 sunny days a year — which is probably why we never quite know whether to wear a raincoat or tank top in May. The answer this weekend? Probably both.
