A Grey Start to May’s First Sunday in Toronto

Rain Arrives Early This Afternoon with a Chance for Thunder Tonight

TORONTO – WEATHER – Toronto is waking up to a mostly cloudy and cool morning this Sunday, with the thermometer currently hovering around 5.7°C at Toronto Pearson International Airport. Winds are sweeping in from the north at 17 km/h, but by mid-morning, expect those winds to pivot from the east, increasing to 20 km/h and gusting up to 40 km/h — perfect weather for inside plans or coffee with a view.

As the barometer sits at 101.5 kPa and falling, the sky is prepping for change. Periods of rain will begin early this afternoon, soaking the city with a high of 15°C expected. The air feels a little sticky this morning with humidity sitting at 78%, and visibility remains clear at 24 kilometres — for now. With a UV index of 7, it’s deceptively high for a cloudy day, so don’t skip the sunscreen if you’re out before the rain hits.

Tonight’s Forecast: Thunder Rolls into the Picture

This evening, the rain will taper off late, but the skies won’t be entirely done with their drama. There’s a 40 percent chance of lingering showers, and the added thrill of a possible thunderstorm rolling in overnight. The wind will maintain its gusty personality, holding steady from the east at 20 km/h and gusting up to 40. Temperatures will dip slightly, settling at a low of 10°C.

Monday: More Showers and Thunder on Tap

The new workweek continues the soggy saga. Monday will remain cloudy with showers developing early in the afternoon. There’s a risk of another thunderstorm in the mix, so keep an umbrella close and your wellies at the ready. The wind ramps up further, coming from the east at 30 km/h and gusting up to 50. The high will hover around 14°C, with the UV index dipping slightly to 6 — still “high” on the scale.

Monday night? Still cloudy with a 40 percent chance of showers and a low of 10°C. If you’re keeping score, that’s three straight days of umbrella weather.

Tuesday: Yet Another Cloudy and Showery Chapter

The grey continues into Tuesday, with a 60 percent chance of showers through the day and a slightly warmer high of 16°C. The night brings a bit of hope, with just a 30 percent chance of showers and the low staying consistent at 10°C.

What to Wear

Raincoats are in, and umbrellas are your best friend over the next few days. Waterproof shoes or boots will be a wise move — nobody likes soggy socks. Layer with a warm hoodie or light jacket for the cool breeze, and don’t be fooled by the clouds — SPF is still your friend!

Historic Weather Tidbit

On this date, May 4th, Toronto has seen a dramatic temperature swing over the years. The record high was a toasty 28.3°C back in 2001, while the record low dipped to a frosty -1.7°C in 1974. Today’s high of 15°C lands right in the middle of this rollercoaster history — proving again that spring in Toronto doesn’t do consistency.
