KMSY by the numbers
What the long-run records say about flying here, computed for this airport alone.
The FAA issued 5 ground stops and 0 ground delay programs for MSY between October 2025 and October 2026, affecting 5 days. Thunderstorms were the most common reason (4 of 5). A typical ground stop lasted about 51 min.
KMSY reported VFR in 85% of daylight observations over 20 years, about 283 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 4% of hours, visibility under 3 miles 2%).
Over 20 years of hourly winds, runway 11 had the best headwind 29% of the time, runway 02 28%, and winds were calm 15% of hours. Winds most often blow from the south. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Thunderstorms were reported on about 87 days a year. 54% of storm hours fall in June, July and August, peaking in July when storms were in the air 5% of the time.
MSY departures left within 15 minutes of schedule 77% of the time across 49,743 flights, June 2025 to May 2026. Before 9 AM departures did best (91%) and 6 to 9 PM did worst (63%).
Over the last 30 days of recorded D-ATIS broadcasts, KMSY ran east flow 81% of the time and mixed configuration 12%. Runway 11 was named for arrivals most often (92% of recorded hours), and the configuration changed 30 times.

Runway wind check
Estimated head/tailwind and crosswind for each runway end from the current reported wind.
Current wind is calm: calm wind is not a factor for runway selection, and with no wind there is no head/tail or crosswind component to compute. Live numbers return automatically once a report includes a wind direction.

“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.
