Saturday morning update:
Showers in Banff are now expected to start as early as 9 am and could continue until 2 pm (https://weather.gc.ca/en/forecast/hourly/index.html?coords=51.179,-115.569).
Canmore remains a dry alternative, or you can stop first in Canmore and continue into Banff in the late afternoon.
Quick summary for anyone heading west this weekend:
Saturday: go early. Environment Canada forecasts showers in Banff from about 11 am to 5 pm, high of 10. Leaving Calgary by 9 gets you there before they start. Canmore is forecast sunny all day, so it’s a good dry alternative.
Sunday: go. Sunny all day in Banff, high of 10.
Roads: 511 Alberta shows Hwy 1 bare and dry, but it is down to one lane at slower speeds at the Jumping Pound Creek bridge (until Oct 31), with occasional lane closures near Bear Hill Road.
Closures and passes:
- Johnston Canyon trail, day-use area and P1 lot are closed until Dec 11 (Parks Canada)
- The Special K Trail to the Grassi Lakes is closed (Alberta Parks)
- Moraine Lake Road is always closed to private vehicles and closed for the season to all vehicles until next summer
- You need a Parks Canada pass if you stop anywhere in Banff National Park
- Remember that Canmore Nordic Centre parking needs a Kananaskis Conservation Pass
Smoke and events: no smoke advisories, no big events in town. Next weekend (Oct 22–24) is the Banff Craft Beer Festival, so expect it to be busier.
Forecasts can shift, so double-check Saturday morning before you leave.
I’m trying to make this a weekly Friday thing. Would this be useful?
Edited to include seasonal restrictions on Moraine Lake Road, K Trail closure, and Saturday morning update.
