KOTM by the numbers
What the long-run records say about flying here, computed for this airport alone.
KOTM reported VFR in 79% of daylight observations over 20 years, about 261 flyable days a year. July is the most reliable month and December the least, with IFR or worse 17% of the time. When conditions drop it is usually a mix of low ceilings (under 1,000 ft 6% of hours) and low visibility (under 3 miles 4%).
Over 20 years of hourly winds, runway 31 had the best headwind 31% of the time, runway 13 28%, and winds were calm 7% of hours. Winds most often blow from the south. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Snow fell on about 35 days a year and freezing rain or drizzle on 5. From December to February KOTM was IFR or worse 15% of the time, against 4% from June to August.
Thunderstorms were reported on about 48 days a year. 54% of storm hours fall in June, July and August, peaking in June when storms were in the air 2% of the time.
Field elevation is 846 ft, but on a median summer afternoon the air performs like 2,470 ft, 1,624 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.
Gusts showed up in 14% of hours, typically 8 kt above the steady wind, and the strongest credible gust on record was 71 kt. April is the windiest month (mean 10 kt) and August the calmest.
Sources: hourly observations 2006 to 2025 and the per-runway wind climatology 2006 to 2025. Historical summaries, not a forecast: check the current METAR, TAF and a briefing before flight.

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 |

“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.
