Morel Mushroom Predictor

Quick “should I go today?” check — based on recent weather

đź§­ We use your input only to fetch coordinates + weather.

Plan your next walk with morel logic, not guesswork.

Type a city, ZIP, or full address. We look at the last ~7 days of weather (temps + rain + soil when available), then estimate how “morel-friendly” it’s been.

🌧️ Rain + warm days = prime
🌡️ Soil ~45–55°F sweet spot
🌳 Old hardwood edges hit different

FAQ + Field Notes

When do morels usually pop?

Typically spring, when soils warm up (often mid-40s to mid-50s °F) and there’s been moisture.

Do certain trees really matter?

Many hunters have luck around mature hardwoods and “indicator” trees like elm, ash, apple, and poplar. This tool lets you add that info as a small bonus.

Safety note (real talk)

Always positively identify mushrooms before eating. If you’re not 100% sure, ask a trusted local mycology group.

Where do the numbers come from?

The app uses Open-Meteo for geocoding and weather.

  • Geocoding: Open-Meteo Geocoding API
  • Weather: Open-Meteo Archive API and/or Forecast API

How does the Python program work?
  • You type a location.
  • Python turns it into GPS coordinates.
  • Python fetches the last ~7 days of weather for that GPS point.
  • Python adds points for soil temp, rain, day temps, night temps, and trees.
  • Python returns a percent score and shows it on the page.
Tiny version: location -> (lat, lon) (lat, lon) -> weather last 7 days weather -> points -> percent
How does the score work?
  • Soil 45–55°F → +30
  • Rain 0.5–2 inches → +25
  • Day 60–75°F → +20
  • Night above 40°F → +15
  • Trees = yes → +10
