A Breezy Morning Turns Brighter by Noon – Humidex Rises to Start the Week
Sunday, June 15 – Cloudy Start, Sunshine to Follow
Toronto begins this Sunday with mostly cloudy skies and a very comfortable 16°C at 7:00 AM EDT, as observed at Pearson International Airport. Humidity sits at 59%, with a dew point of 8.1°C, and the air feels refreshingly dry compared to the muggy days of recent memory. A gentle northeast breeze at 10 km/h adds to the crisp early summer feel. The pressure is 102.0 kPa and gently falling, suggesting a subtle shift in conditions through the day.
By midday, expect the clouds to break, revealing a mix of sun and cloud for the afternoon. Temperatures will climb to a lovely high of 22°C, with the UV index hitting a very high 9 — so don’t be fooled by morning gloom; the sun will make its presence known.
Tonight – A Quiet Evening Before the Clouds Return
Tonight brings a few clouds lingering after sunset, but skies will cloud over again before morning. Expect a mild low of 14°C, ideal for patio time or an evening stroll — just don’t forget a light jacket.
Monday, June 16 – Humidity and Heat Sneak In
Monday starts off mainly cloudy, but clearing in the afternoon will allow temperatures to rise to 24°C. Thanks to building moisture in the air, it will feel more like 29°C with the humidex — summer is back, Toronto style. The UV index remains very high at 8, so you’ll need that SPF handy again.
Winds remain light, keeping the day calm, but potentially muggy. Skies will stay cloudy overnight, with a low of 16°C.
Tuesday, June 17 – Chance of Showers Returns
By Tuesday, it’s cloudy with a 30% chance of showers, and the temperature will climb to 26°C — a more humid and unsettled day is on deck. The evening holds onto cloudy skies, with a continued 30% chance of showers, and a warm low of 18°C.
What to Wear
Today calls for light layers — you might need a sweater early on, but switch to short sleeves or breezy fabrics by afternoon. Sunglasses and sunscreen are essential from midday onward. Tomorrow? Think summer wardrobe: breathable cottons, water bottle in hand, and maybe a fan if your Monday involves commuting.
