KBUU by the numbers
What the long-run records say about flying here, computed for this airport alone.
KBUU reported VFR in 78% of daylight observations over 20 years, about 257 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 8% of hours) and low visibility (under 3 miles 6%).
Over 20 years of hourly winds, runway 19 had the best headwind 32% of the time, runway 29 32%, and winds were calm 25% of hours. Winds most often blow from the south-southwest. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Snow fell on about 44 days a year. From December to February KBUU was IFR or worse 15% of the time, against 7% from June to August.
Fog was reported on about 34 days a year, and fog or mist on 119. August and September are the foggiest months, with fog in 9% of hours, against 4% in April.
Gusts showed up in 19% of hours, typically 6 kt above the steady wind, and the strongest credible gust on record was 46 kt. April is the windiest month (mean 7 kt) and August the calmest.

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.

“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.
