Live aviation weather for Washington Dulles International Airport in Dulles, VA, including METAR, TAF, ATIS, flight category, wind, visibility, ceiling, altimeter and runway crosswinds.

Washington Dulles International Airport (KIAD) is one of the primary air-carrier airports serving Dulles, VA at a field elevation of 312 ft. KIAD 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 4 physical runways (01C/19C, 01L/19R, 01R/19L, 12/30), the longest 11,500 ft. The official FAA airport diagram is at the bottom of the page.

Current pilot readout for KIAD

KIAD is currently VFR with winds from 180° at 3 knots, visibility 10+ statute miles, and a 3,100 ft ceiling. The tower TFDM states arrivals on runway 19C, 19L and 19R and departures on runway 30; crosswind on the active runways is approximately 0–3 kt; the wind favors south-facing runway ends (19C, 19L, 19R). Density altitude is approximately -350 ft (field elevation 312 ft). Review the latest TAF below for forecast changes before departure.

84%
of daylight hours VFR, 2006 to 2025

KIAD reported VFR in 84% of daylight observations over 20 years, about 290 flyable days a year. July is the most reliable month and December the least, with IFR or worse 13% 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 4%).

35%
of windy hours favor 19C, 19L, 19R

Over 20 years of hourly winds, the south-facing ends (19C, 19L, 19R) had the best headwind 35% of the time, runway 30 29%, and winds were calm 23% of hours. Winds most often blow from the south. Crosswind on the best available runway topped 15 kt in under 1% of hours.

35
thunderstorm days a year

Thunderstorms were reported on about 35 days a year. 69% of storm hours fall in June, July and August, peaking in July when storms were in the air 2% of the time.

83%
of departures on time, June 2025 to May 2026

IAD departures left within 15 minutes of schedule 83% of the time across 58,239 flights, June 2025 to May 2026. Before 9 AM departures did best (91%) and 6 to 9 PM did worst (70%).

71%
north flow in the last 30 days

Over the last 30 days of recorded D-ATIS broadcasts, KIAD ran north flow 71% of the time and south flow 29%. Runway 01R was named for arrivals most often (68% of recorded hours), and the configuration changed 299 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.
