KTWF 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 TWF in the 12 months to October 2026. Delays here come from the airlines or from programs at other airports rather than from TWF's own airspace.
KTWF reported VFR in 93% of daylight observations over 20 years, about 312 flyable days a year. July is the most reliable month and January the least, with IFR or worse 12% of the time. When conditions drop it is usually a mix of low ceilings (under 1,000 ft 1% of hours) and low visibility (under 3 miles 2%).
Over 20 years of hourly winds, runway 26 had the best headwind 42% of the time, runway 12 31%, and winds were calm 7% of hours. Winds most often blow from the south. Crosswind on the best available runway topped 15 kt in 1% of hours.
Snow fell on about 43 days a year and freezing rain or drizzle on 2. From December to February KTWF was IFR or worse 9% of the time, against under 1% from June to August.
Thunderstorms were reported on about 22 days a year. 63% of storm hours fall in May, July and August, peaking in August when storms were in the air 1% of the time.
Field elevation is 4,153 ft, but on a median summer afternoon the air performs like 6,723 ft, 2,570 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.
