KJST 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 JST in the 12 months to October 2026. Delays here come from the airlines or from programs at other airports rather than from JST's own airspace.
KJST reported VFR in 66% of daylight observations over 20 years, about 197 flyable days a year. July is the most reliable month and January the least, with IFR or worse 32% of the time. When conditions drop it is usually a mix of low ceilings (under 1,000 ft 12% of hours) and low visibility (under 3 miles 9%).
Over 20 years of hourly winds, runway 23 had the best headwind 45% of the time, runway 33 28%, and winds were calm 9% of hours. Winds most often blow from the west. Crosswind on the best available runway topped 15 kt in 1% of hours.
Snow fell on about 73 days a year and freezing rain or drizzle on 13. From December to February KJST was IFR or worse 29% of the time, against 10% from June to August.
Fog was reported on about 88 days a year, and fog or mist on 209. January and February are the foggiest months, with fog in 23% of hours, against 11% in June.
Gusts showed up in 21% of hours, typically 8 kt above the steady wind, and the strongest credible gust on record was 57 kt. January is the windiest month (mean 10 kt) and August the calmest.

“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.
