Flight categories at JFK

Pilots sort every weather report into four flight categories using the lowest cloud ceiling and the visibility. The chart shows how many hours each month fall short of VFR, split by how far short.

May has the highest share of IFR-or-worse hours. For LIFR alone, the highest share is in May; for MVFR it is in October.

VFR
Ceiling above 3,000 feet and visibility above 5 miles.
MVFR
Marginal VFR. Ceiling of 1,000 to 3,000 feet, or visibility of 3 to 5 miles.
IFR
Ceiling of 500 to under 1,000 feet, or visibility of 1 to under 3 miles.
LIFR
Ceiling under 500 feet, or visibility under 1 mile.

A ceiling counts only broken or overcast layers, or vertical visibility into fog or heavy precipitation. A few scattered clouds do not count.

Fog

0.90% of hours report fog, about 79 hours per year.

Fog has its highest monthly share in December and its lowest in August. Across all months, it is most frequent 7 am to 8 am.

The longest sequence of hourly fog reports lasts 23 hours. This counts routine reports, so short events between reports can be missed.

Wind and runway crosswinds

Runway axes and true headings come from OurAirports.

The most frequent wind sector is S, among reports with sustained wind of at least 3 kt.

Using the better aligned runway axis, the crosswind component stays at or below 13 kt in 96.6% of hours with a wind-speed report.

The share with wind or gusts of at least 25 kt is highest in March and lowest in August. Crosswind above 15 kt on every available axis is most frequent in March.

The largest sustained wind or reported gust in these hourly observations is 69 kt.

Temperature, humidity and daylight

Daily temperature comes from GHCN-Daily.

July has the highest average daily high; January has the lowest.

Dew points of at least 70°F are most frequent in July.

Mid-month daylight is longest in June and shortest in December. Sunrise and sunset use the configured US daylight saving rule.

Average high and low by month

Lines are the average. Shaded bands cover the middle 80% of days.

Best and worst months by hazard

Each row is a different weather problem. A stronger colour means a higher rate that month, and the three worst months for each hazard have the strongest colour.

Hazard calendar

The strongest-coloured cells are the three worst months for that row. A pale cell with a 0 means none at all.

Planning with JFK climate records

For travelers

  • August has the lowest historical IFR-or-worse rate. A monthly average does not predict weather on a particular trip.

For pilots

  • Use the charts to compare historical conditions. Get current METARs, TAFs and an official briefing before flying.

This page is for general information and trip planning. It is not an aviation weather briefing and must not be used for flight planning. Always get current weather from an official source such as aviationweather.gov or 1-800-WX-BRIEF before flying.

Sources and method

Sources

Hourly weather
Iowa Environmental Mesonet archive of US National Weather Service routine hourly observations, report type 3, requested in UTC and filtered to local years 2000 to 2025.
Daily climate
NOAA NCEI GHCN-Daily station USW00094789. Menne et al. (2012), Global Historical Climatology Network Daily, doi:10.7289/V5D21VHZ.
Runways
OurAirports public domain runway data: source repository. Headings are degrees true. The first listed runway represents each numbered axis in crosswind calculations.
Time and daylight
Standard UTC offset -5 hours; US daylight saving rule, including the earlier rule before its statutory change. Solar times use the airport coordinates and NOAA equations.

Definitions

Sampling
One routine report per local clock hour. The first report is retained when hours repeat, including the autumn clock change.
Weather codes
Fog and thunderstorms exclude vicinity codes.
Wind
The stronger of sustained wind and gust is used for crosswind. Calm and variable direction count as zero crosswind.
Daily averages
Monthly totals and day counts are divided by the number of years in the analysis period.

Limits

  • Routine hourly sampling misses events between observations.
  • Wind above 100 kt, temperature outside -30 to 115 F and dew point outside -40 to 90 F are discarded as sensor glitches.
  • Wind-only runway preferences do not describe ATC assignments.

Weather data comes from the US National Weather Service and NOAA via IEM. PilotPassion is not affiliated with or endorsed by these agencies.
