14-day history · 7-day trend

This estimate currently covers Europe between 44–60° N and -9–27° E.

How is this estimate made?

Experimental scoring, not yet calibrated against field observations. Moisture history: 40 points; temperature: 30; rain distribution: 15; frost, heat and wind: 15. Today uses the previous 14 complete days, with temperature evaluated over 7 days. Future days use a rolling window that includes forecast weather.

The water balance is rain minus reference evapotranspiration, not a soil moisture measurement. Past data also comes from weather models. Location grouping of roughly 3–6 km and weather-grid resolution cannot describe a forest microclimate. The general index may be misleading for winter and specialist species.

The species list and index do not replace expert inspection of mushrooms collected for consumption.
