KMSO by the numbers
What the long-run records say about flying here, computed for this airport alone.
The FAA issued no ground stop or ground delay program for MSO in the 12 months to October 2026. Delays here come from the airlines or from programs at other airports rather than from MSO's own airspace.
KMSO reported VFR in 91% of daylight observations over 20 years, about 298 flyable days a year. July is the most reliable month and January the least, with IFR or worse 14% of the time. When conditions drop it is usually fog and low visibility rather than low ceilings (visibility under 3 miles 4% of hours, ceilings under 1,000 ft 2%).
Over 20 years of hourly winds, runway 30 had the best headwind 65% of the time, runway 12 35%, and winds were calm 42% of hours. Winds most often blow from the northwest. Crosswind on the best available runway topped 15 kt in 1% of hours.
Snow fell on about 62 days a year and freezing rain or drizzle on 3. From December to February KMSO was IFR or worse 12% of the time, against 1% from June to August.
MSO departures left within 15 minutes of schedule 84% of the time across 4,891 flights, June 2025 to May 2026. Before 9 AM departures did best (93%) and 3 to 6 PM did worst (78%).
Fog was reported on about 42 days a year, and fog or mist on 115. January and December are the foggiest months, with fog in 22% of hours, against under 1% in July.

Runway wind check
Estimated head/tailwind and crosswind for each runway end from the current reported wind.
Current wind is calm: calm wind is not a factor for runway selection, and with no wind there is no head/tail or crosswind component to compute. Live numbers return automatically once a report includes a wind direction.
| Runway | Length | Surface | Head / Tail | Crosswind |
|---|---|---|---|---|
| 12 | 9,501 ft | ASP | - | - |
| 30 | 9,501 ft | ASP | - | - |

“Current use” is what the facilitystates; wind components are arithmetic on the current METAR against TRUE headings; status reflects NOTAMs received through SWIM, the tower's TFDM record and the D-ATIS — a runway reads “Open” only with a complete NOTAM picture.
