What to Wear in Toronto in August
What to wear in Toronto in August? With average highs of 77°F and lows of 62°F, August remains hot and humid in Toronto — humidex readings near 100°F are still possible, though the month gradually transitions toward slightly less intense heat. Lightweight breathable clothing and sun protection remain the priority.
August in Toronto carries forward July's heat and humidity with a subtle shift toward autumn by month's end. The humidex still climbs toward 100°F during heat waves, and the Toronto Islands, Harbourfront, and the CNE grounds (where the Canadian National Exhibition runs from mid-August through Labour Day) are popular outdoor destinations that require heat-appropriate clothing. The real Toronto August signature is the CNE — Canada's largest annual fair runs on the Exhibition Place grounds for two weeks, combining outdoor midway rides, food halls, and entertainment in full late-summer heat. Comfortable, breathable clothing and flat shoes for hours of walking across the 190-acre grounds are the practical requirements. By late August, the first hints of autumn begin — a cool morning, a lower humidity day — that Torontonians greet as a welcome relief after two months of humid heat.

Frequently Asked Questions
What should I wear in Toronto in August?+
Continue wearing lightweight breathable clothing from July — moisture-wicking fabrics, shorts, light tops, and breathable footwear. The CNE at Exhibition Place is the major August event and requires comfortable walking clothes for hours in the heat. By late August, evenings can drop to 62°F or occasionally lower — a light layer for outdoor dining becomes useful toward month-end.
Is August a good time to visit Toronto?+
August is excellent for Toronto — the Canadian National Exhibition (CNE) at Exhibition Place runs from mid-August through Labour Day, the waterfront is fully active, TIFF (Toronto International Film Festival) begins in the last days of August, and the city is at peak summer energy. Heat and humidity remain significant, but the outdoor scene and events justify the climate challenge for well-prepared visitors.
What shoes should I wear in Toronto in August?+
The CNE's 190-acre Exhibition Place grounds demand comfortable, broken-in walking shoes or sneakers that can handle hours of pavement. Sandals work well for the waterfront and casual exploring but can fatigue on a full CNE day. Breathable mesh sneakers or athletic shoes handle the heat better than leather or canvas styles. A compact rain option handles August's continuing afternoon storm pattern.
How hot is Toronto in August?+
August averages 77°F (25°C) highs and 62°F (17°C) lows — slightly cooler than July but still firmly in summer territory with significant humidity. Humidex readings near 95–100°F (35–38°C) remain possible during August heat waves. By late August, a noticeable shift toward cooler mornings begins, with some days dropping to the high 50s°F overnight.
What should I pack for Toronto in August?+
Pack similarly to July: moisture-wicking lightweight tops, shorts and a light pair of trousers for evenings, breathable walking shoes, a packable rain jacket for thunderstorms, and sunscreen SPF 50+. Add a light cardigan or thin pullover for the increasingly cool late-August evenings and for the famously aggressive air conditioning in the CNE's indoor buildings and Toronto's restaurants.
