If you're deciding on Missoula for 2026-08-29 – 2026-08-30, start with the numbers, then the plan.

Should you plan around Missoula's forecast this weekend?

Missoula, Montana

Weekend air in Missoula sits near 66°F / 46°F, plus a dry outlook with little to no rain — enough to decide whether the trip is on.

Treat Missoula as the whole trip: build the day around trail-friendly highs, then fill gaps with the local picks below.

If the numbers still look good by Friday, lock the plan around 66°F — not a vague “nice weather somewhere.”

Things to do

What to pack

What to pack1
  • Evening temperatures can drop from about 66°F to 46°F after sunset — pack a layer.
Packing checklist8
  • Closed-toe walking shoes — Better for cool temps and city miles
  • Jeans or warmer pants — Comfortable coverage in cool weather
  • Light jacket or cardigan — Evenings and air-conditioned spaces
  • Sweater / fleece — Cool daytime highs and cooler evenings
  • Hiking boots / trail shoes — Support and traction on trails
  • Bug spray — Mosquitoes and ticks outdoors
  • Daypack — Water, layers, and snacks on trails
  • Lip balm — Dry air and cold wind crack lips quickly

Bottom line

Go if the outlook still matches what you want. Missoula is the trip — not a shortlist to compare.

Keep planning
