Aviation Weather REST API

METAR

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

TAF

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

PIREP

Inflight observations meant to aid controllers and pilots routing around adverse conditions and others of note

AIR / SIGMET

Global source of inflight weather advisories for turbulence, thunderstorms, icing, and more

NOTAM

Notices detailing special events or human-made conditions affecting airport and flight operations

NBM

Atmospheric forecasts up to eight days in advance from NOAA's National Blend of Models

Station Info

Station data includes name, idents, coordinates, runways, and other useful fields

Search

Reports and stations can be returned from a text search, nearest a coordinate pair, or along a flight path

Reliable Sources

Most reports are pulled from NOAA ADDS, the official source for aviation weather for pilots in the US with world-wide, but support exists for additional sources on a regional basis. Station information is compiled from OurAirports

Data Analysis

Reports are sanitized eliminating common errors with manual entry. Flight rules are calculated for each time period in the report. Additional features like value interpretation, translation, and text-to-speech are available per element and for the report as a whole

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 and IoT applications

Documentation

API docs are available on Apiary. Additional help can be found on the support site

Open-Source

All AVWX code and documentation is available on GitHub for security audits. Pull requests are welcome

About

AVWX is a publicly-available REST API for aviation weather. The service organizes METAR, TAF, and other report types into their individual elements and returns them in JSON, XML, or YAML format. It does a considerable 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.

Pricing

AVWX offers three pricing tiers: hobby, pro, and enterprise. The basic METAR and TAF parsing services are free, but other features require monthly or yearly paid plans. Check out the pricing guide for more information.

Additionally, the developers will gladly accept donations if a monthly plan is not an option. Thank you in advance!

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.

VATSIM

Virtual Air Traffic Simulation network

FleetCaptain

Flight school fleet management

AeroLink

Flight bag app for South America

AvBot

Discord bot for flight sims
