Hyppykeli

Hyppykeli.fi is a weather service for skydivers, providing current observations and forecasts for wind gusts, direction, cloud coverage, and cloud height. Data comes from FMI observation stations and Digitraffic road weather stations. Upper-wind forecasts come from Open-Meteo, and METAR messages from the Flyk.com API.

Forecasts are available anywhere in Finland, but useful observations require a nearby observation station.

The service was created by Esa-Matti Suuronen with help from other skydiving nerds and is free for everyone. The GPL-licensed source code is available on GitHub.
