KSTS 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 STS in the 12 months to October 2026. Delays here come from the airlines or from programs at other airports rather than from STS's own airspace.
KSTS reported VFR in 78% of daylight observations over 20 years, about 287 flyable days a year. June is the most reliable month and December the least, with IFR or worse 27% 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 10%).
Over 20 years of hourly winds, runway 14 had the best headwind 46% of the time, runway 20 25%, and winds were calm 39% of hours. Winds most often blow from the south. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Fog was reported on about 120 days a year, and fog or mist on 232. January and December are the foggiest months, with fog in 35% of hours, against 6% in June.
STS departures left within 15 minutes of schedule 81% of the time across 5,279 flights, June 2025 to May 2026. Before 9 AM departures did best (91%) and 6 to 9 PM did worst (77%).
Winds were calm 34% of the time and averaged 4.0 kt overall. May is the windiest month (mean 5 kt) and November the calmest.

Runway wind check
Estimated head/tailwind and crosswind for each runway end from the current reported wind.
Current wind is variable at 3 kt: light and variable wind like this is generally not a factor for runway selection, and with no steady direction there is no head/tail or crosswind component to compute. Live numbers return automatically once a report includes a wind direction.
| Runway | Length | Surface | Head / Tail | Crosswind |
|---|---|---|---|---|
| 02 | 5,202 ft | ASP | - | - |
| 14 | 6,000 ft | ASP | - | - |
| 20 | 5,202 ft | ASP | - | - |

“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.
