Get the latest METAR for an airport. Returns raw METAR plus decoded ceiling, visibility, wind, and VFR/MVFR/IFR/LIFR flight category.

Get the Terminal Area Forecast (TAF) for an airport. Returns raw TAF plus decoded forecast periods with flight category, wind, visibility, and ceiling.

Get pilot reports (PIREPs) near an airport. Reports recent turbulence, icing, cloud tops, and other in-flight observations.

Get active SIGMETs and AIRMETs. Filter by region to reduce noise.

Get DWD ICON-D2 NWP forecast for any lat/lon. Provides hourly wind (10m + 80m), visibility, cloud base, precipitation, and CAPE. ICON-D2 covers Central Europe at 2km resolution up to 48h. Falls back to ICON-EU (7km, Europe) or ICON-seamless outside coverage.

Longer-range VFR confidence outlook (3–15 days) for an airfield or location. Pools an ensemble (ECMWF-ENS for low cloud; ECMWF-ENS + GEFS for CAPE) and reports, per day, the probability that the day is NO-GO — the share of ensemble members with poor VFR conditions (low cloud above threshold OR high CAPE/thunderstorm potential) during the daylight window. Also shows the deterministic ECMWF-IFS trend, plus the ICON-EU run (≤5 days) as an independent medium-range cross-check that sits between ICON-D2 (48h) and ECMWF (15d). This is the confidence measure for trip planning that short-range METAR/TAF/ICON-D2 cannot provide. Pass an ICAO code (resolved offline from a bundled airport database covering GA fields) or lat/lon directly.

VFR preflight weather brief for an airfield. Combines current METAR, TAF, and ICON-D2 NWP forecast into a single assessment. Only the ICAO code is required — coordinates are resolved authoritatively from the aviationweather.gov station database. Never supply coordinates yourself.

Route weather brief for a direct flight between two airports. Fetches METARs at departure and destination, ICON-D2 at 5 points along the great-circle route, and active SIGMETs. Coordinates are resolved from the station API — never guess them. Pass ICAO codes exactly as given by the user.
