KBDU by the numbers

What the long-run records say about flying here, computed for this airport alone.

90%
of daylight hours VFR, 2006 to 2025

KBDU reported VFR in 90% of daylight observations over 20 years, about 319 flyable days a year. August is the most reliable month and February the least, with IFR or worse 10% of the time. When conditions drop it is usually low ceilings rather than fog (ceilings under 1,000 ft 4% of hours, visibility under 3 miles 2%).

50%
of windy hours favor runway 08

Over 20 years of hourly winds, runway 08 had the best headwind 50% of the time, runway 26 50%, and winds were calm 33% of hours. Winds most often blow from the west-southwest. Crosswind on the best available runway topped 15 kt in 3% of hours.

44
snow days a year

Snow fell on about 44 days a year. From December to February KBDU was IFR or worse 7% of the time, against 1% from June to August.

72
thunderstorm days a year

Thunderstorms were reported on about 72 days a year. 67% of storm hours fall in May, June and July, peaking in June when storms were in the air 3% of the time.

7,935 ft
typical summer-afternoon density altitude

Field elevation is 5,288 ft, but on a median summer afternoon the air performs like 7,935 ft, 2,647 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.

10%
of hours with gusts

Gusts showed up in 10% of hours, typically 8 kt above the steady wind, and the strongest credible gust on record was 76 kt. April is the windiest month (mean 5 kt) and September the calmest.
