Live aviation weather for Chicago O'Hare International Airport in Chicago, IL, including METAR, TAF, ATIS, flight category, wind, visibility, ceiling, altimeter and runway crosswinds.

Chicago O'Hare International Airport (KORD) is one of the primary air-carrier airports serving Chicago, IL at a field elevation of 680 ft. KORD 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 8 physical runways (04L/22R, 04R/22L, 09C/27C, 09L/27R, 09R/27L, …), the longest 13,000 ft. The official FAA airport diagram is at the bottom of the page.

Current pilot readout for KORD

KORD is currently VFR with winds from 170° at 9 knots, visibility 10+ statute miles, and no ceiling reported. The tower TFDM states arrivals on runway 09L, 10C and 10R and departures on runway 09C and 10L; crosswind on the active runways is approximately 9 kt; the wind favors southwest-facing runway ends (22L, 22R). Density altitude is approximately 1,300 ft (field elevation 680 ft). Review the latest TAF below for forecast changes before departure.

KORD by the numbers

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

228
FAA ground stops and delay programs, last 12 months

The FAA issued 154 ground stops and 74 ground delay programs for ORD between October 2025 and October 2026, affecting 91 days. Thunderstorms were the most common reason (131 of 228). A typical ground stop lasted about 1 h 22 min.

Full ORD delay history →

78%
of daylight hours VFR, 2006 to 2025

KORD reported VFR in 78% of daylight observations over 20 years, about 259 flyable days a year. July is the most reliable month and December the least, with IFR or worse 15% 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%).

32%
of windy hours favor 22L, 22R

Over 20 years of hourly winds, the southwest-facing ends (22L, 22R) had the best headwind 32% of the time, the west-facing ends (27C, 27L, 27R, 28C, 28L, 28R) 29%, and winds were calm 8% of hours. Winds most often blow from the west. Crosswind on the best available runway topped 15 kt in under 1% of hours.

52
snow days a year

Snow fell on about 52 days a year and freezing rain or drizzle on 5. From December to February KORD was IFR or worse 14% of the time, against 3% from June to August.

73%
of departures on time, June 2025 to May 2026

ORD departures left within 15 minutes of schedule 73% of the time across 355,671 flights, June 2025 to May 2026. Before 9 AM departures did best (86%) and 6 to 9 PM did worst (61%).

ORD delays by hour and weekday →

59%
east flow in the last 30 days

Over the last 30 days of recorded D-ATIS broadcasts, KORD ran east flow 59% of the time and mixed configuration 21%. Runway 28C was named for arrivals most often (52% of recorded hours), and the configuration changed 392 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.
