Current pilot readout for KSFO
KSFO is currently VFR with winds from 290° at 15 knots, visibility 10+ statute miles, and a 20,000 ft ceiling. The tower TFDM states arrivals on runway 28R and 28L and departures on runway 28R, 01R, 28L and 01L; crosswind on the active runways is approximately 2–15 kt; the wind favors northwest-facing runway ends (28L, 28R). Density altitude is approximately 200 ft (field elevation 13 ft). Review the latest TAF below for forecast changes before departure.
KSFO by the numbers
What the long-run records say about flying here, computed for this airport alone.
The FAA issued 76 ground stops and 259 ground delay programs for SFO between October 2025 and October 2026, affecting 217 days. Other or unspecified was the most common reason (136 of 335). A typical ground stop lasted about 1 h 16 min.
KSFO reported VFR in 81% of daylight observations over 20 years, about 288 flyable days a year. October is the most reliable month and August the least, with IFR or worse 9% of the time. When conditions drop it is usually low ceilings rather than fog (ceilings under 1,000 ft 5% of hours, visibility under 3 miles 1%).
Over 20 years of hourly winds, the northwest-facing ends (28L, 28R) had the best headwind 63% of the time, the southwest-facing ends (19L, 19R) 17%, and winds were calm 12% of hours. Winds most often blow from the west. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Fog was reported on about 17 days a year, and fog or mist on 73. January and December are the foggiest months, with fog in 9% of hours, against 1% in August.
SFO departures left within 15 minutes of schedule 78% of the time across 145,890 flights, June 2025 to May 2026. Before 9 AM departures did best (92%) and noon to 3 PM did worst (71%).
Over the last 30 days of recorded D-ATIS broadcasts, KSFO ran northwest flow 100% of the time. Runway 28R was named for arrivals most often (95% of recorded hours), and the configuration changed 104 times.

“Current use” is what the tower TFDM configurationstates; 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.
