Mushroom forecast
Mushroom forecast for Switzerland, today and the next 7 days
Every day, MycoRadar calculates for the forests of all Switzerland how well the weather, soil, forest and terrain suit each mushroom species. You see the result for today and the following seven days, free of charge and in every canton.

Each value takes the best forest sector. Every sector, species and day is on the map in the app.
What the forecast calculates
A mushroom forecast describes conditions: it compares what a forest offers today with what a species needs. To do this, MycoRadar combines the rain and temperatures of recent days with the weather forecast and the stable features of the place: altitude, aspect, soil, forest type and tree species. A forest can therefore stay low after rain if it is too cold or if the species does not find its trees there.
The result is an index from 0 to 100 for each forest sector and each species. A high value means that the calculated conditions suit the species well. The data comes from sources including MeteoSwiss, swisstopo, FOEN, WSL and SwissFungi.
How to read the map
In the app, MycoRadar colours forest areas as hexagons, from red for unfavourable conditions to teal for the best ones. Choose a day and the map shows the conditions forecast for that day. On a Wednesday, you can see the conditions forecast for Sunday. The forecast goes no further than seven days.
Open a hexagon to read the zone sheet: altitude, rain, soil, tree species and the mushroom species whose habitat matches the place. Compare the same place over several days, which tells you more than a single value.
Every morning, weather, soil, forest and terrain are recalculated for each sector. The app also has a history: around the place you choose and over the period you want, you find 35 years of observations, 36,700 in all, placed on the same grid.
The app shows known restrictions on the map.
Mushroom picking rules in SwitzerlandWhich species, in which season
The species catalogue in the app places common morels from March to June, golden chanterelles from June to November, penny buns and wood hedgehogs from July to November, and horns of plenty from August to November. Depending on the year, the altitude and the region, the season starts and ends earlier or later. The MycoWiki sheets describe the features, habitat and look-alikes of each species.
After the outing: the official inspection
Inspection specialists examine your mushrooms. VAPKO, the Swiss association of official mushroom inspection bodies, lists the inspection points, and MycoRadar shows them with address and contact details.

More than a forecast
MycoRadar stays with you all season. Uni teaches you in short lessons to tell species and their look-alikes apart. MycoWiki explains species, habitats, host trees and rules, and the audio guide comes with you into the forest.
Rules by canton
The MycoWiki page on Switzerland sets out the quantity limits, protected periods and other rules of each of the 26 cantons, as compiled by VAPKO.
