Free Mushroom Map Soil, weather & burn data
Most “free” foraging tools give you just enough to be frustrating — a teaser map with no data, or a sign-up wall before you can see anything useful.
Forayz works differently. The free tier includes actual environmental layers: soil moisture, soil temperature, 14-day precipitation, snowcover, ecoregions, and rainfall normals. Open it and start checking conditions. These are the same layers I use to decide whether a trip is worth the drive.
What’s Free in Forayz
The free tier includes every environmental layer on the map. These are the conditions that drive mushroom fruiting, and having them in one place saves hours of checking weather stations, soil databases, and SNOTEL sites individually.
Soil Temperature
The single most important variable for timing morel hunts. Morels fruit when soil temps hit roughly 50°F (10°C). The map shows you exactly where that threshold is being reached across the Pacific Northwest and Western US — instead of guessing based on air temperature or elevation.
Soil Moisture
Moisture is the second half of the equation. A warm burn site that hasn’t seen rain in three weeks isn’t going to produce. This layer helps identify areas with enough water in the ground to support fruiting — especially important later in the season when exposed slopes dry out fast.
14-Day Cumulative Precipitation
How much rain has fallen in the last two weeks. Useful for spotting moisture pockets in otherwise dry areas, and for timing trips after spring or fall rain events. Chanterelle and bolete hunters find this layer especially valuable in the fall.
Snowcover
In spring, snowcover tells you which burns and high-elevation sites have melted out and which are still buried. No point driving three hours to a site under two feet of snow. Updates regularly so you can watch the melt progress in real time.
Ecoregions
Ecoregion boundaries help you understand the landscape at a glance — what kind of forest you’re looking at, what elevation band you’re in, and what species are likely to grow there. Useful when planning trips to unfamiliar areas.
Rainfall Normals
Long-term precipitation averages by area. Is this spot generally wet or dry? Combined with the 14-day precipitation layer, you can identify areas running wetter or drier than usual — which can mean better or worse conditions than the map suggests alone.
Check conditions before your next trip
Open the free map, turn on soil temperature and moisture, and see what’s happening at your target spots right now. No sign-up, no credit card.
What Forayz Pro Adds
The free layers are enough for general foraging — checking conditions, timing trips, understanding the landscape. If you’re specifically hunting burn morels or doing serious backcountry scouting, Pro unlocks the layers that matter most for that work.
Burn Maps
Wildfire burn perimeters from recent years across the entire Western US. First-year burns are where the big morel fruitings happen, and having every burn mapped on one screen saves an enormous amount of research time. 2026 burn maps are live.
Timber Harvest Maps
Recently logged and thinned forest areas. These are underrated morel spots that most foragers overlook — timber harvests create similar conditions to burns, but with less competition because fewer people are looking at harvest data.
Morel Fruiting Predictions
Town-by-town timing predictions for Oregon and Washington based on soil temperature trends, precipitation, and elevation. Unique to Forayz — no other foraging app generates predictions like this. Also includes weekly burn condition write-ups covering soil temp, snowcover, moisture, and weather forecast.
Offline Map Downloads
Download map areas to your phone for use without cell service. Essential for backcountry foraging where you’re miles from a tower. Download your target areas at home, then navigate in the field without worrying about signal.
How Foragers Use the Free Map
Fall chanterelle scouting: Check soil moisture and 14-day precipitation for your usual spots before making the drive. If the ground is dry, save the gas.
Spring morel timing: Watch soil temperature maps in March and April. When your target elevation band crosses 50°F and there’s been recent rain, it’s go time.
Planning a trip to a new area: Use ecoregions and rainfall normals to understand what kind of forest and moisture regime you’re headed into. Cross-reference snowcover if you’re heading to higher elevations.
General mushroom scouting: Soil moisture, temperature, and precipitation together tell you whether conditions are favorable for fruiting in any area, for any species. These are the fundamentals.

If you’re foraging casually or hunting species that don’t depend on burn data — chanterelles, boletes, hedgehogs, lobster mushrooms — the free tier is a complete tool. Start there.
If you’re chasing burn morels, want offline maps for backcountry use, or want the fruiting predictions, Pro pays for itself on your first trip that would’ve been a bust without the data.
