How we measure accuracy
Every forecast published on Zefita is stored and compared the next day with real observations from official weather stations. We calculate the mean temperature error, the share of days forecast correctly within ±2 °C and how often rain was correctly predicted. The method follows World Meteorological Organization guidance.
