Weather and climate in Otepää
Otepää is the winter capital of Estonia, on the Otepää Upland. The higher position and hilly landscape make the winter here snowier and longer than in most of Estonia - ski competitions are held at Tehvandi, and the area around Lake Pühajärv is a centre of winter sports.
For a skier, the temperature around zero and the snow line are what matter - and that is exactly where the models often diverge. The range across the nine models shows whether the snow forecast for the weekend is certain.
Where this forecast comes from
Most weather sites show a single model and give the impression that the answer is certain. Ilmapiir compares nine national weather models at once: ECMWF, Germany's DWD ICON, the US GFS, the UK Met Office, Météo-France, Norway's MET, Canada's GEM, Japan's JMA and China's CMA. When the models agree, you can rely on the forecast; when they diverge, it is more honest to say that it is only a probability.
Ilmapiir also records the measured temperature every hour and compares it with what each model promised a day earlier. This gives a rolling 30-day average error for every model - an answer to the question of whom to believe.
Thunderstorms and warnings
The lightning map shows strikes in real time, and your phone can alert you when lightning strikes within a chosen distance of a chosen place. Official warnings from the Estonian Environment Agency are shown in the interactive view, and the rain radar shows where it is raining right now - the radar image updates every 10 minutes.
