KSJC 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 SJC in the 12 months to October 2026. Delays here come from the airlines or from programs at other airports rather than from SJC's own airspace.
KSJC reported VFR in 89% of daylight observations over 20 years, about 325 flyable days a year. June is the most reliable month and August the least, with IFR or worse 3% of the time. When conditions drop it is usually low ceilings rather than fog (ceilings under 1,000 ft 2% of hours, visibility under 3 miles 1%).
Over 20 years of hourly winds, the northwest-facing ends (30L, 30R) had the best headwind 68% of the time, the southeast-facing ends (12L, 12R) 32%, and winds were calm 26% of hours. Winds most often blow from the northwest. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Seasonal hazards are rare at KSJC: thunderstorms on about 2 days a year, fog on 7 and snow on 0. Wind is the main variable, with gusts in 4% of hours.
SJC departures left within 15 minutes of schedule 82% of the time across 43,699 flights, June 2025 to May 2026. Before 9 AM departures did best (94%) and 6 to 9 PM did worst (73%).
Over the last 30 days of recorded D-ATIS broadcasts, KSJC ran northwest flow 98% of the time and southeast flow 2%. Runway 30L was named for arrivals most often (83% of recorded hours), and the configuration changed 9 times.
