Best time to visit Banff: month by month
Short answer
Mid-June to September is the best time for hiking and turquoise lakes: July highs average about 24°C with nights around 9°C. Late September brings the gold larches with fewer people. July and August are the busiest and most expensive months, while December to April suits skiing, with highs below freezing.

Season by season
Spring (Mar–May)
Cool and changeable, from about 2°C in March to 13°C in May; lakes stay frozen until late May or June and high trails are snowbound.
Summer (Jun–Aug)
Highs of 20–24°C and long days; the lakes turn turquoise from late June, but June is also the rainiest month (about 15 rainy days) and crowds peak in July–August.
Autumn (Sep–Nov)
September is crisp at about 18°C with larches turning gold late in the month; by November highs drop below freezing and the ski season approaches.
Winter (Dec–Feb)
Cold, with highs around -4 to -7°C and lows near -15°C; skiing at Sunshine Village, Lake Louise and Norquay, and skating on frozen lakes.

When to avoid
April to early June is a shoulder season of slush, frozen lakes and closed trails. July and August are wonderful but crowded and costly; if you must go then, book rooms and shuttles months ahead.
