Cloudy Skies Today, More Sun by Sunday — Classic Mid-June Mood Swings
Friday: Cool, Cloudy, and Calm
Toronto kicks off Friday, June 13, under mostly cloudy skies and a mild morning temperature of 13.9°C at 6:00 AM EDT, according to observations from Toronto Pearson International Airport. Humidity sits at 68%, and a steady east wind at 19 km/h adds a touch of breeze to the otherwise calm start. Visibility is excellent at 24 km, and the barometric pressure is rising at 102.2 kPa, signaling a stable — if a little overcast — day ahead.
Today’s forecast brings mainly cloudy skies and a high of 19°C. It’s a bit cooler than the seasonal norm but still pleasant for daytime plans. The UV index is 8, considered very high, so even with the cloud cover, you’ll want to lather on some sunscreen if you’re heading outside.
Tonight: Cloudy but Comfortable
Skies will remain mostly cloudy tonight, but it will stay dry and mild. The overnight low will be 14°C, ideal for an evening walk or just letting the fresh air roll through the windows as you wind down the week.
Saturday: Cloud and Sun Jockey for Position
Saturday brings a mix of sun and cloud, with the temperature holding steady near 15°C throughout the day. While it won’t be the warmest, it will be comfortable enough for outdoor plans like farmer’s markets, garden work, or a walk along the waterfront. The UV index jumps to 9, so even with cloud breaks, sun protection is a must.
Saturday night stays dry with cloudy periods and another mild low of 14°C.
Sunday: A Toastier Turn
Sunday is shaping up to be the weekend’s best weather day, with a mix of sun and cloud and a warmer high of 23°C — finally giving us a taste of true June heat. Winds will stay light, and with no rain expected, it’s a perfect day for picnics, parks, or hitting the patios. Sunday night will be cloudy at times, with a low of 15°C, staying comfortably warm through the evening.
What to Wear
Friday and Saturday mornings may feel a little cool, so bring a light jacket. By afternoon, you’ll be fine with long sleeves or a hoodie. With high UV levels, sunscreen and sunglasses are smart additions — especially on Saturday and Sunday when the sun makes more frequent appearances. And while it stays cloudy, it’s wise to keep an umbrella nearby just in case a stubborn drizzle appears (though none is expected yet).
Historic Weather Trivia
Toronto has seen its share of weather drama on June 13. The record high for this date is 31.3°C, set in 2005 — a far cry from today’s mid-teens. The record low was 7.2°C, recorded in 1966. So, while today’s high of 19°C may seem modest, it’s right on brand for a Toronto June that can’t quite decide if it’s spring or summer.
