Wind, thermals, convergence and soundings on one map, at 1.3 km resolution where AROME reaches. When the model shows nothing workable, the app says so instead of guessing.

AROME · ICON-D2 · Open-Meteo

Planning a flight shouldn't need five open tabs.

Most pilots stitch together several apps and a sounding tool before every flight. Each shows one slice of the day. None of them put wind, thermals and convergence on the same map at the same hour, for the exact spur you're eyeing.

Generic grid modelsCoarse 2.5 km cells miss the ridge you actually fly. Aerya runs at 1.3 km where AROME reaches.

Scattered signalsWind, thermals, convergence, soundings — one map, one timeline, one place to check before you drive to launch.

No "why is it empty?"When the model has no data, most apps just show a blank screen. You can't tell if it's broken or calm.

Three things, nothing else.

A thermal forecast, the models behind it, and a clear answer when there's no data. That's the whole app.

Thermal strength forecast

Hourly thermal strength across Europe at 1.3 km resolution, driven by AROME. Colour-coded so you can read at a glance whether the day is on or off.

Multi-source NWP

AROME (1.3 km) is primary. ICON-D2 covers the German Alps. Open-Meteo fills in everywhere else. When a source is down, you see which one you're getting.

No mystery blanks

Calm air and missing data look identical on most weather maps. Aerya labels both: a "no thermals expected" state and a source badge when you're seeing Open-Meteo instead of AROME.

Built by a paragliding pilot.

Aerya sits on public weather and terrain data — AROME, ICON-D2, Open-Meteo, SRTM, ESA WorldCover. It doesn't invent anything the models don't say; it puts what they do say on one map, with the source labelled.

Thermals, convergence zones, and real soundings — terrain factored in

Data source always visible, fallbacks labelled

Anonymous flight feedback improves the thermal model — opt-in, never sold
