A Bright and Breezy Start to the Week with Summer-Like Sunshine and a Hint of Fog
From Fog to Fabulous: Clear Skies and 22°C Ahead for the GTA
TORONTO – WEATHER – Monday, May 26, 2025 – The Greater Toronto Area is easing into the new week under clear skies and mild spring temperatures, as early-morning fog patches begin to fade away. If you’re headed out early, there’s a chill in the air, but by afternoon, expect to bask in full sunshine with highs touching 22°C—just the way late May should feel.
At 5:00 AM EDT, Toronto Pearson International Airport reported a temperature of 7.8°C with a dew point of 5.3°C, producing a notably damp 84% humidity—hence the patchy fog. Winds are calm from the north-northwest at 7 km/h, and visibility sits at 24 km. Barometric pressure is at 102.4 kPa and rising, indicating fair weather on the move.
Today’s forecast is simple: sunny skies after morning fog patches dissipate, with temperatures climbing to a comfortable high of 22°C. However, it will be cooler near Lake Ontario, where the lake breeze will keep shoreline communities around 14°C. The UV index is 7, considered high, so sunscreen and shades are in order.
Tonight brings clear skies and a low of 9°C—perfect sleeping weather for those still holding off on the AC.
What’s Ahead: From Sun to Rain by Midweek
Tuesday continues the stretch of good weather, bringing mainly sunny skies and a high of 22°C inland, though again cooler near the lake. Winds shift to the east at 20 km/h by late afternoon. The UV index climbs to 8, which is very high—hat and SPF are a must if you’re outdoors.
Clouds roll in Tuesday night, leading to a cooler, wetter shift midweek. Wednesday is expected to bring showers and a high of just 14°C, followed by periods of rain into the evening with lows around 11°C.
Thursday keeps things grey with a 30 percent chance of showers during the day and 40 percent at night, with daytime highs around 17°C.
It’s a tale of two halves this week—sunny and serene to start, then soggy and subdued by midweek.
Wardrobe Suggestion
Layers are your best friend today—start with a jacket or sweater for the morning chill, but swap it for a tee or light long sleeve by noon. If you’re lake-bound, bring something warmer—those breezes aren’t kidding.
Weather Trivia: Fog and the 401
Did you know? Toronto’s early morning fog events, like today’s, are most common in spring when cool overnight temperatures meet the residual daytime warmth trapped in the city’s surface materials. It’s part of the reason fog can form in the suburbs and disappear before it even reaches downtown!
