Packing for Toronto in August means dressing for 25°C days and 18°C evenings. A light cotton tee with a casual overshirt works well at 25°C, the overshirt doubles as a layer for air-conditioned venues. Evening temperatures settle at 18°C, a modest 7°C drop that a light cardigan or denim jacket covers. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. A compact foldable umbrella weighs almost nothing and earns its keep across 9 potential rainy days.
Local tip: Layers are more practical than a single heavy garment in Toronto. The day-to-evening temperature shift rewards packing a versatile mid-layer you can add or remove as conditions change.
