When is the best time to visit Calgary?
July and August offer the most dependable warmth, with daytime highs near 23°C and long daylight hours. For snowbirds and March-break travellers, late April through May is a sweet spot: crowds are thin, hotel rates are lower, and the city’s famous chinook winds can bring sudden thaws. If you’re chasing winter sports, December to February delivers reliable snow and crisp, sunny days.
What should I pack for Calgary weather?
Layers are non-negotiable. Even in summer, evenings drop to 8–10°C, so a fleece or light jacket is essential. Winter visitors need a heavy parka, insulated boots, and a good toque—wind chills often push below –20°C. Spring and autumn demand a waterproof shell and a warm mid-layer; rain is possible in May and June, with monthly precipitation averaging 50–80 mm.
Where can I find a Calgary weather 60-day forecast?
