What to pack for Banff in summer, in the Canadian Rockies

In July and August, Banff and Jasper reach about 22 to 23 °C (72 to 73 °F) by day and drop to 6 to 7 °C (43 to 45 °F) at night. Afternoon thunderstorms are common. Pack layers, a waterproof rain jacket, broken-in hiking boots, and bear spray, bought or rented when you arrive.

The story

You leave Banff at six in the morning to beat the crowds, and it’s 6 °C. By the time the shuttle drops you at Moraine Lake, the sun is on the peaks and the water is an unreal turquoise, colored by the fine rock dust the glaciers grind into it. You’re wearing a fleece and a hat, and you keep them on for the first hour of the hike.

At the trailhead, a sign lists recent bear sightings. The couple next to you asks where to buy bear spray: you can’t bring it on a plane, so you picked up a canister in Banff the day before, and it rides on your hip belt where you can reach it. You hike as a group, talking loudly around blind corners, and the only animal you meet is a marmot whistling from a rock.

By noon it’s 24 °C and you’re in a T-shirt, eating lunch by a lake so clear you can see every stone on the bottom. You dip a hand in: the water is barely above freezing. At two, dark clouds build over the ridge, thunder rolls down the valley and a cold rain starts. Your rain jacket comes out of the backpack, and the fleece goes back on.

Later that week you drive the Icefields Parkway to Jasper and stop at the Athabasca Glacier. It’s windy and cold at the edge of the ice, even in August, and the signs warn you not to walk onto the glacier without a guide: hidden crevasses have killed people here.

The Canadian Rockies in summer can give you three seasons in one day. Pack layers, a real rain jacket and good boots, and treat the mountains, and the bears, with respect.
