June - August

Summer in Banff often brings warm, sunny weather, although cool temperatures are not uncommon. The alpine comes to life this time of year, with the lakes taking on their vivid turquoise hues, the wildflowers in bloom, and hiking trails at higher elevations mostly snow free. July is the warmest month, with average highs of 22°C (72°F). Being at an elevation of above 1,400 metres (4,600 feet), the evenings can cool off significantly. If you’re planning a summer visit, be sure to still pack a few warmer layers!
