KGRB 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 GRB in the 12 months to October 2026. Delays here come from the airlines or from programs at other airports rather than from GRB's own airspace.
KGRB reported VFR in 77% of daylight observations over 20 years, about 249 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 6% of hours) and low visibility (under 3 miles 5%).
Over 20 years of hourly winds, runway 24 had the best headwind 33% of the time, runway 18 26%, and winds were calm 13% of hours. Winds most often blow from the west. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Snow fell on about 54 days a year and freezing rain or drizzle on 4. From December to February KGRB was IFR or worse 14% of the time, against 5% from June to August.
GRB departures left within 15 minutes of schedule 80% of the time across 4,830 flights, June 2025 to May 2026. Before 9 AM departures did best (91%) and 6 to 9 PM did worst (69%).
Thunderstorms were reported on about 30 days a year. 65% of storm hours fall in June, July and August, peaking in July when storms were in the air 1% of the time.
