Nile Mushroom Calendar

Nile sits in the Eastern Cascades Slopes and Foothills and a notably dry climate, with roughly 9 inches of annual rainfall, most of it falling in the cool months from fall into spring. The ground warms and reaches early fruiting potential around April, by which point the average last frost (May 8) has usually passed. Like much of the Pacific Northwest, summers around Nile run dry, and flushes show up only sporadically where localized rain falls; the season picks up again in October with the return of autumn rains. Winter then shuts the season down hard and early.
