People pack for a Banff summer like it's summer anywhere else. July averages 23°C (73°F) in the afternoon but only 8°C (46°F) at dawn, and mountain weather turns fast once you're up at a lake or on a ridge. Bring a warm layer and a rain shell every single day, whatever the month.

What shoes should you pack for Banff?
Waterproof hiking shoes or boots with real tread for Johnston Canyon, Tunnel Mountain and the climb to Lake Agnes. Bring sneakers for town. In winter you need insulated boots with grip, and slip-on traction cleats help on icy paths.
What do people wear in Banff?
Outdoorsy and casual. Fleece, puffer jackets, hiking pants and beanies are normal everywhere, including the nicer restaurants on Banff Avenue. No one dresses up, so pack for warmth and comfort.
What plugs does Banff use?
Canada uses type A and B sockets at 120V, the same as the US. Visitors from the UK, Europe and Australia need an adapter, and a universal one covers it. Cold drains phone batteries quickly, so keep a power bank in an inside pocket.

Packing for Banff: questions people ask
What should I wear in Banff in summer?
Layers. Afternoons reach 17–23°C (63–73°F) but mornings start at 3–8°C (37–46°F), so bring a fleece, a rain shell and waterproof hiking shoes.
How cold is Banff in winter?
Highs of -1°C (30°F) to -3°C (27°F) and lows down to -16°C (3°F) in February. You need an insulated coat, thermals, a hat, gloves and warm boots.
Do I need bear spray in Banff?
Parks Canada recommends carrying it on trails and knowing how to use it. You can't fly with it, so buy it in town when you arrive.
When is the best time to visit Banff?
July to September for hiking and December to March for skiing. September is our pick, with 19°C (66°F) highs, only 7 rain days and the larches turning.
Do I need a plug adapter for Banff?
Only if your home country doesn't use A and B plugs. Canada uses type A and B sockets at 120V, so visitors from the UK, Europe and Australia need one.
