🌡️ Airport Weather Forecast
Live METAR observations, TAF forecasts & 7-day temperature predictions from multiple sources
About This Tool
Search any airport worldwide by its ICAO code to get real-time weather observations (METAR), terminal forecasts (TAF), and 7-day max/min temperature predictions. Data is sourced from multiple providers and each reading shows its source for full transparency.
Data Sources
- AviationWeather.gov (METAR): Real-time hourly weather observations from airport weather stations worldwide. Operated by NOAA/FAA. Includes temperature, dewpoint, wind, visibility, pressure, and cloud cover.
- AviationWeather.gov (TAF): Official terminal aerodrome forecasts covering 24-30 hours. Updated every 6 hours with amendments as conditions change.
- Open-Meteo: Free weather forecast API aggregating the best global models — NOAA GFS, ECMWF, DWD ICON, and more. Provides 7-day daily max/min temperature and precipitation probability.
Understanding METAR Reports
METAR is a standardized format for weather observations at airports. Key elements include: temperature and dewpoint (in °C), wind direction and speed (in knots), visibility, cloud cover (FEW/SCT/BKN/OVC at altitude), and atmospheric pressure (altimeter setting).
Flight Categories
- VFR (Visual Flight Rules): Ceiling > 3,000ft and visibility > 5sm
- MVFR (Marginal VFR): Ceiling 1,000-3,000ft or visibility 3-5sm
- IFR (Instrument Flight Rules): Ceiling 500-999ft or visibility 1-3sm
- LIFR (Low IFR): Ceiling < 500ft or visibility < 1sm
How to Read a METAR — Worked Example
Consider the report KJFK 121651Z 18012KT 10SM FEW050 24/14 A2992. Decoded, this means: station KJFK (New York JFK), observed on the 12th at 16:51 UTC, wind from 180° at 12 knots, visibility 10 statute miles, few clouds at 5,000 ft, temperature 24°C with a dewpoint of 14°C, and an altimeter setting of 29.92 inHg. Once you recognise the fixed order of these groups, even a dense METAR becomes quick to read.
Why Airport Weather Data Is Reliable
Airport observations are among the most accurate weather data available because aviation safety depends on them. METAR readings come from calibrated instruments at the airfield and are updated hourly (or more often when conditions change rapidly), while TAF forecasts are issued by professional meteorologists. By combining these official aviation sources with multi-model forecast data from Open-Meteo, this tool gives you both verified current conditions and a forward-looking 7-day outlook, with each value labelled by its source so you can judge its reliability.
Limitations of Weather Prediction
No forecast is certain. Accuracy is very high for the next 24–48 hours but degrades noticeably beyond about 5 days, because the atmosphere is a chaotic system where tiny differences compound over time. Treat the 7-day temperature outlook as a trend rather than a guarantee, and always check the most recent observation for current conditions. Localised events such as thunderstorms can develop faster than any forecast model updates.
Frequently Asked Questions
METAR (Meteorological Aerodrome Report) is an hourly weather observation from an airport weather station. It includes temperature, dewpoint, wind speed/direction, visibility, cloud cover, and atmospheric pressure.
TAF (Terminal Aerodrome Forecast) is a weather forecast specific to an airport, typically covering a 24-30 hour period. It predicts wind, visibility, clouds, and significant weather phenomena.
ICAO codes are 4-letter identifiers for airports worldwide (e.g., KJFK for New York JFK, EGLL for London Heathrow, VIDP for Delhi). US airports start with K, European with E or L, and Indian with V.
Current conditions (METAR) and forecasts (TAF) come from AviationWeather.gov (FAA/NOAA). The 7-day temperature forecast comes from Open-Meteo, which aggregates multiple weather models including NOAA GFS, ECMWF, and DWD ICON.
METAR observations are issued every hour (sometimes more frequently during severe weather). TAF forecasts are updated every 6 hours. Open-Meteo forecasts update hourly.
Yes! Enter any valid ICAO code worldwide. Examples: EGLL (London Heathrow), LFPG (Paris CDG), RJTT (Tokyo Haneda), VIDP (Delhi), YSSY (Sydney).
METAR shows the actual observed temperature right now. TAF shows aviation-focused forecasts. Open-Meteo provides model-based predictions. Differences of 1-3°F between forecast sources are normal due to different models and resolutions.
