KRIW 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 RIW in the 12 months to October 2026. Delays here come from the airlines or from programs at other airports rather than from RIW's own airspace.
KRIW reported VFR in 93% of daylight observations over 20 years, about 323 flyable days a year. July is the most reliable month and February the least, with IFR or worse 5% of the time. When conditions drop it is usually fog and low visibility rather than low ceilings (visibility under 3 miles 2% of hours, ceilings under 1,000 ft 1%).
Over 20 years of hourly winds, runway 28 had the best headwind 39% of the time, runway 01 26%, and winds were calm 18% of hours. Winds most often blow from the northwest. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Snow fell on about 44 days a year and freezing rain or drizzle on 1. From December to February KRIW was IFR or worse 6% of the time, against under 1% from June to August.
Thunderstorms were reported on about 26 days a year. 68% of storm hours fall in June, July and August, peaking in August when storms were in the air 1% of the time.
Field elevation is 5,516 ft, but on a median summer afternoon the air performs like 8,215 ft, 2,699 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.

“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.
