Before any flight the pilot in command is required to obtain the current aeronautical information from the AIP and recent changes in the form of NOTAMs. Obtaining and interpreting actual and forecast weather is also part of the preflight procedure.
The Aviation Weather Center of NOAA (National Oceanic and Atmospheric Administration) supplies pilots with the latest information, advisories, forecasts and observations. We have selected their METAR/TAF product for easy access on our site.
The latest FAA Advisory Circular AC-00-45H Change-1 is also available here. It explains the US weather products and services in detail.
Below you can enter the airport ICAO code, keep in mind that not all airports have meteorological services to produce metars or tafs or when they do, some do not even report these to the Aviation Digital Data Service (ADDS) at all.
The list below explains the features of the request form. Just enter any valid airport ICAO or IATA ID, make your choice in options and then press the button 'Get METAR/TAF' to obtain the report, it will open in a new window.
If you have a need to convert the temperature, pressure or relative humidity in the reports, we have some calculators below that might be of help to you. Enter the values in the yellow boxes and press the calculate button.
Below we have dew point and relative humidity calculators (cloud level is a rough estimate):
Aviation weather reports can be obtained from different sources and most countries have different formats. To assist with that EuroControl created a guidance note helping pilots obtaining weather reports before their flight.
During your flight it can be useful to update your weather picture, read the next document on how to get an inflight weather update.
