KISP 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 ISP in the 12 months to October 2026. Delays here come from the airlines or from programs at other airports rather than from ISP's own airspace.
KISP reported VFR in 77% of daylight observations over 20 years, about 264 flyable days a year. November is the most reliable month and May the least, with IFR or worse 20% of the time. When conditions drop it is usually low ceilings rather than fog (ceilings under 1,000 ft 11% of hours, visibility under 3 miles 6%).
Over 20 years of hourly winds, the northwest-facing ends (33L, 33R) had the best headwind 34% of the time, runway 24 32%, and winds were calm 12% of hours. Winds most often blow from the southwest. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Snow fell on about 23 days a year and freezing rain or drizzle on 3. From December to February KISP was IFR or worse 14% of the time, against 11% from June to August.
ISP departures left within 15 minutes of schedule 75% of the time across 5,020 flights, June 2025 to May 2026. Before 9 AM departures did best (92%) and 6 to 9 PM did worst (53%).
Fog was reported on about 42 days a year, and fog or mist on 147. May and December are the foggiest months, with fog in 16% of hours, against 5% in August.
