KBTM 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 BTM in the 12 months to October 2026. Delays here come from the airlines or from programs at other airports rather than from BTM's own airspace.
KBTM reported VFR in 92% of daylight observations over 20 years, about 310 flyable days a year. July is the most reliable month and February the least, with IFR or worse 8% of the time. When conditions drop it is usually fog and low visibility rather than low ceilings (visibility under 3 miles 3% of hours, ceilings under 1,000 ft 1%).
Over 20 years of hourly winds, runway 30 had the best headwind 34% of the time, runway 15 26%, and winds were calm 33% of hours. Winds most often blow from the northwest. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Snow fell on about 83 days a year and freezing rain or drizzle on 0. From December to February KBTM was IFR or worse 6% of the time, against 1% from June to August.
Thunderstorms were reported on about 34 days a year. 81% of storm hours fall in June, July and August, peaking in July when storms were in the air 2% of the time.
Field elevation is 5,550 ft, but on a median summer afternoon the air performs like 7,770 ft, 2,220 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.

“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.
