The foraging index above answers that: 0–3 means poor conditions, 4–6 average, 7–10 excellent. It is computed from soil moisture and temperature, the past week of rain, and each species’ season window.

Fruiting bodies emerge roughly 7–14 days after substantial rain, while the soil stays warm and moist — exactly the window the index tracks as its "trigger". The "Best day" marker in the 7-day forecast above gives the concrete recommendation.

From five measured Open-Meteo inputs (soil moisture and temperature, rain, air temperature and humidity), weighted by species phenology — porcini, chanterelles, boletes and honey fungus. A 0–10 scale, updated daily.
