A seven-day foraging forecast built from weather, woodland and terrain, covering 495 regions. Mushrooms lead — but berries and wild plants have their own seasons, and we track those too. Not a map of other people's finds: a number that changes every day.

Where to begin

What we forecast — and, since you have probably not heard of us, how we test it and what it stands on.

Where the flush is running

The field is interpolated from a network of sample points — the same way meteorologists draw a rainfall map from a network of stations.

Countries and regions

Every region and county has its own page with a week's forecast and the towns inside it. Hover to stop the ribbon.

My spots

Your own patch, one tap away

The forecast is computed on a grid of sample points. You do not walk a grid point — you walk your own wood, and finding it again is harder than it sounds: five kilometres off is a different forecast.

  1. 1Tap the spot on the forecast map and save it — it stays yours and goes nowhere.
  2. 2Next time come back to it in one tap, instead of hunting for the same wood by eye.

This list lives in this browser and never reaches our servers. It will not follow you to another device, and clearing your history erases it.

Why you can trust the number

The same data national weather services use

Not intuition, and not a digest of other people's reports. Everything that feeds the index is named, licensed and checkable.

  • 2.5 km

    map resolution

    Two woods in the same county are not the same wood, and the map shows it. Not an average over a region — a particular place.

  • Weeks

    not «it rained yesterday»

    Fruiting does not follow the rain by a day; it follows by one to two weeks, and the lag differs by species. The model carries a month of weather and knows each lag.

  • Per species

    each one modelled separately

    A penny bun, a chanterelle and a saffron milkcap want different weather and different trees. A single «mushroom index» for all of them is an answer for nobody.

  • Backtested

    against finds we did not collect

    We test the forecast against independent field records and publish the result — including where it falls short of our own threshold. Nobody else in this field does that.

Behind the index are the same numerical weather models national forecasters run, 10-metre satellite land cover, and a separate model for each species. Every source, licence and collection date is listed in full on the data page.

How it works

Three layers of data instead of one look at the sky

The index is not folklore. Three sources are computed together and refreshed every six hours.

01

Weather with a memory

The model does not read yesterday's shower; it reads the last month, and it knows how many days after rain each species appears. Soil moisture at 7–28 cm matters more than rainfall — mycelium responds to what reached it a fortnight ago.

02

A place, not a region

Woodland, conifer share, elevation, slope and protected areas are computed per map cell. The same rain in a hollow and on a south slope gives a different result — an average over a region cannot know that.

03

The phase of the flush, not just a number

Quiet → Starting → Building → Peak → Fading. You see not only how much today, but where the week is going: go now or wait three days are different answers, and the number alone gives neither.

Plainly

What the index promises, and what it does not

A forecast model gets things wrong. We would rather say so here than lose your trust once.

We promise

  • A number recomputed every six hours from weather and season — never a static page.
  • An honest confidence beside the index, rather than one confident-looking percentage.
  • A visible «demo data» badge wherever a region is not yet on live weather.
  • Readable factors («rain over the past week — too little») instead of a bare «+18».

We do not promise

  • A pin on the map where mushrooms certainly grow — this is not a map of finds.
  • That a high index means mushrooms at the particular spot you drive to.
  • Any advice on edibility. Nothing here tells you that anything is safe to eat.
  • A substitute for care around poisonous lookalikes and legally protected species.

Questions

Frequently asked

Am I allowed to pick here?

We cannot answer that yet, and we would rather say so than guess. Foraging rights in Europe differ not just by country but by landowner and by protected status: Italy issues permits region by region, England depends on whether the land is access land and on the owner's permission, and nature reserves have their own rules almost everywhere. A legality layer is the next thing we are building. Until it exists, check the rules for the specific place you are going.

Is this a map of mushroom spots?

No, and the difference matters. A map of finds answers «where», from other people's pins. We answer «when»: the forecast is built from weather, season and the history of the flush, and it changes every day. We have no crowd-sourced map of spots, and we do not pretend otherwise.

What does the «demo data» badge mean?

For some regions we do not yet have live weather, and the forecast runs on climate normals instead. Where that is the case the page shows a «demo data» badge beside the number. It reflects the real state of the service, not decoration, and it disappears by itself once the region moves to live weather.

How often does the forecast update?

The scheduler recomputes every six hours from the past week's weather, and pages refresh with it — at least hourly.

The index is high but I found nothing — why?

The index reads weather and season — things that are the same for tens of kilometres around. It does not know your particular wood, and that is where the mushroom grows. The usual reasons: wrong trees — every species has its own, and no weather makes up for the wrong stand; the wood was felled recently or is young — the mycelium takes years to recover; the spot is picked out — everything near a road or a car park goes over a weekend; the flush has been taken — you came a day after those who came on time; or the flush passed and slugs and larvae got there first, which the model cannot see. The reverse holds too: a low index does not mean an empty wood. It means the conditions are against you, not that there is nothing there.

How accurate is it?

We publish the answer rather than claim one. Tested against independent field records, the model ranks the day of a real find above a random day in the same place about 61% of the time, where 50% would be a coin toss. That is better than chance and short of the threshold we set ourselves beforehand. The full figures, including the ones that flatter us least, are on the «how we check» page.

Does it tell me whether something is safe to eat?

No. Nothing on this site tells you that anything is edible. We show where and when species are likely to be fruiting, and we name dangerous lookalikes — but identification in the field is yours, and where you are unsure the answer is to leave it.
