Klamath Falls Mushroom Calendar

Klamath Falls sits in the Eastern Cascades Slopes and Foothills and a notably dry climate — about 11.1 inches of rain a year, most of it falling in the cool months from fall into spring. The ground warms and reaches early fruiting potential around May, by which point the average last frost (Jun 9) has usually passed. Summer dries out — June through September typically see under an inch of rain — and fruiting goes quiet until the rains return in October, kicking off the year's main flush. Winter then shuts the season down hard and early.
