Aviation Weather REST API



METAR

Current surface conditions at an airport or other reporting location that updates every hour or earlier

TAF

In-flight 24-hour forecast for an area within 5nm of an airport or other reporting station that updates every six hours


Reliable Sources

Most reports are pulled from aviationweather.gov, the offical source for aviation weather for pilots in the US, but support exists for additional sources on a regional basis. Coordinate-to-station is pulled from geonames.org, one of the most widely used sources of geography data

Data Analysis

Not only is the report organized but every element is error-corrected and analyzed to provide additional information like flight rules

Cross-Platform

Parsed reports are returned in JSON, XML, or YAML format, which can be imported into any language on any platform. Great for battery-conscientious mobile applications

Documentation

API docs are available on Apiary



Open-Source

The AVWX API and core library are open-source on GitHub


About

The AVWX REST API is a publically-available REST API for aviation weather. The service organizes METAR and TAF reports into their individual elements and returns them in JSON, XML, or YAML format. It does a considderable amount of error correction so that your report is as clean and thorough as possible. It has additional services like providing station information, translating the report into English, and creating summary strings meant to be read or spoken. For more details, check out the documentation.

Is AVWX Free?

AVWX's METAR and TAF parsing services are free. However, while the underlying library is freely available, hosting this API costs money (about $200/month at its current usage). Your support is always welcome. If AVWX is powering your paid or commercial application, please support AVWX on a recurring basis. Thank you!

Who uses AVWX?

The parser itself has been field-tested and in use since September 2014. It was originally made for a Raspberry Pi IoT project, but was eventually made available as a public API. I've been contacted by flight schools, research institutions, and many mobile and desktop application developers. Here are a few of my favorite projects using AVWX.
