George Bush Intercontinental Airport (KIAH) Aviation Weather: METAR, TAF & ATIS

As of 5:53 PM CDT, Oct 28, KIAH is currently VFR with winds from 150° at 9 knots, visibility 10+ statute miles, and a 25,000 ft ceiling. The FAA lists no ground stop or delay program for KIAH right now.

Live aviation weather for George Bush Intercontinental Airport in Houston, TX, including METAR, TAF, ATIS, flight category, wind, visibility, ceiling, altimeter and runway crosswinds.

George Bush Intercontinental Airport (KIAH) is one of the primary air-carrier airports serving Houston, TX at a field elevation of 96 ft. KIAH reports its own METAR and publishes a TAF, and broadcasts digital ATIS (D-ATIS), decoded live on this page as flight category, wind, visibility, ceiling and altimeter. It has 5 physical runways (08L/26R, 08R/26L, 09/27, 15L/33R, 15R/33L), the longest 12,001 ft. The official FAA airport diagram is at the bottom of the page.

Current pilot readout for KIAH

KIAH is currently VFR with winds from 150° at 9 knots, visibility 10+ statute miles, and a 25,000 ft ceiling. The tower TFDM states arrivals on runway 08R, 09 and 08L and departures on runway 15R and 15L; crosswind on the active runways is approximately 0–8 kt; the wind favors southeast-facing runway ends (15L, 15R). Density altitude is approximately 1,150 ft (field elevation 96 ft). Review the latest TAF below for forecast changes before departure.

KIAH by the numbers

What the long-run records say about flying here, computed for this airport alone.

87
FAA ground stops and delay programs, last 12 months

The FAA issued 62 ground stops and 25 ground delay programs for IAH between October 2025 and October 2026, affecting 50 days. Thunderstorms were the most common reason (46 of 87). A typical ground stop lasted about 1 h 16 min.

Full IAH delay history →

81%
of daylight hours VFR, 2006 to 2025

KIAH reported VFR in 81% of daylight observations over 20 years, about 275 flyable days a year. August is the most reliable month and February the least, with IFR or worse 17% of the time. When conditions drop it is usually low ceilings rather than fog (ceilings under 1,000 ft 6% of hours, visibility under 3 miles 3%).

45%
of windy hours favor 15L, 15R

Over 20 years of hourly winds, the southeast-facing ends (15L, 15R) had the best headwind 45% of the time, the northwest-facing ends (33L, 33R) 24%, and winds were calm 18% of hours. Winds most often blow from the south. Crosswind on the best available runway topped 15 kt in under 1% of hours.

62
thunderstorm days a year

Thunderstorms were reported on about 62 days a year. 46% of storm hours fall in May, June and July, peaking in June when storms were in the air 2% of the time.

78%
of departures on time, June 2025 to May 2026

IAH departures left within 15 minutes of schedule 78% of the time across 119,193 flights, June 2025 to May 2026. Before 9 AM departures did best (90%) and 6 to 9 PM did worst (70%).

IAH delays by hour and weekday →

73%
east flow in the last 30 days

Over the last 30 days of recorded D-ATIS broadcasts, KIAH ran east flow 73% of the time and mixed configuration 14%. Runway 08L was named for arrivals most often (82% of recorded hours), and the configuration changed 207 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.
