A Dramatic Sky Over the 6ix Today
A Look at Thursday, May 1, 2025
Toronto is starting the day under a blanket of mostly cloudy skies with a current temperature of 6.5°C, observed at 6:00 AM from Toronto Pearson International Airport. A brisk northeast wind is sweeping through at 10 km/h and is expected to pick up to 20 km/h, gusting to 40 km/h by mid-morning. Atmospheric pressure is at 101.9 kPa but is on the decline—stormy signs, indeed! Humidity sits at 57%, giving the morning air a crisp, early-spring bite.
The city can expect increasing cloudiness as the morning progresses, with a 30 percent chance of showers by late morning and early afternoon. Showers will become more likely this afternoon, with a risk of a thunderstorm rolling through later in the day—so don’t forget your umbrella and maybe reconsider outdoor lunch plans unless you enjoy a bit of drama with your sandwich.
Temperatures will rise to a high of 13°C today, with a UV index of 7, which is considered high. Despite the grey skies, the sun’s rays still pack a punch—so if the sun peeks through, sunscreen won’t go amiss.
Tonight, showers will gradually taper off after midnight but not without a few potential thunderous interruptions. There’s still a 30 percent chance of lingering drizzle and fog patches will develop overnight, reducing visibility for any late-night excursions. Winds will shift to the east at 20 km/h before calming down by midnight. The low will be a relatively mild 11°C.
Outlook for Friday and the Weekend
Friday, May 2, starts under a veil of lingering fog patches that will lift as the morning moves along. Skies will remain cloudy with a 30 percent chance of showers throughout the day. The southwest wind will kick things up a notch, becoming 20 km/h and gusting to a blustery 60 km/h. Hold on to your hats—and your coffee cups! Temperatures will climb to a much more spring-appropriate 18°C, with a moderate UV index of 5.
Friday night continues cloudy with a lingering 30 percent chance of showers and a low of 9°C, leading into Saturday where the trend of clouds and slight chances of rain remains. Expect a high of 15°C on Saturday before skies finally clear up that night, with a dip to a low of 5°C.
Historic Weather Snapshot
On this date in Toronto’s history, the warmest May 1st ever recorded hit a toasty 29.1°C back in 2001. In stark contrast, the chilliest May 1 dipped down to a frosty -3.9°C in 1966. Today’s forecast finds us comfortably nestled somewhere in between—perfectly Toronto.
What to Wear?
With wind, rain, and possibly thunder on the menu, it’s a day for layers, waterproof jackets, and sturdy shoes. Don’t forget your umbrella, and maybe add a hat to keep the wind-tousled look at bay. Sunglasses might still make a cameo, especially if the sun muscles through the clouds.
