What to Wear in Toronto in June
Packing for Toronto in June means dressing for 24°C days and 12°C evenings. A light cotton tee with a casual overshirt works well at 24°C, the overshirt doubles as a layer for air-conditioned venues. Evenings drop 12°C to around 12°C, a notable shift that catches underprepared visitors off guard. Pack a dedicated evening layer. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues.
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.
