Current pilot readout for KSTL
KSTL is currently VFR with winds from 190° at 7 knots, visibility 10+ statute miles, and a 20,000 ft ceiling. The D-ATIS states arrivals on runway 12R and 11 and departures on runway 12R; crosswind on the active runways is approximately 6 kt; the wind favors southeast-facing runway ends (11, 12L, 12R, 24). Density altitude is approximately 950 ft (field elevation 617 ft). Review the latest TAF below for forecast changes before departure.
KSTL by the numbers
What the long-run records say about flying here, computed for this airport alone.
The FAA issued 3 ground stops and 0 ground delay programs for STL between October 2025 and October 2026, affecting 2 days. Thunderstorms were the most common reason (2 of 3). A typical ground stop lasted about 1 h 22 min.
KSTL reported VFR in 83% of daylight observations over 20 years, about 280 flyable days a year. June is the most reliable month and December the least, with IFR or worse 11% 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 2%).
Over 20 years of hourly winds, the southeast-facing ends (11, 12L, 12R) had the best headwind 31% of the time, the northwest-facing ends (29, 30L, 30R) 29%, and winds were calm 12% of hours. Winds most often blow from the south. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Snow fell on about 31 days a year and freezing rain or drizzle on 6. From December to February KSTL was IFR or worse 11% of the time, against 2% from June to August.
STL departures left within 15 minutes of schedule 76% of the time across 63,718 flights, June 2025 to May 2026. Before 9 AM departures did best (90%) and after 9 PM did worst (54%).
Over the last 30 days of recorded D-ATIS broadcasts, KSTL ran southeast flow 59% of the time and northwest flow 41%. Runway 12L was named for arrivals most often (54% of recorded hours), and the configuration changed 85 times.

“Current use” is what the D-ATISstates; 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.
