Darrington Mushroom Calendar

Darrington sits in the North Cascades and one of the wetter corners of the region, with roughly 83.1 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 (Apr 16) has usually passed. Rain barely lets up even at the height of summer, so something is usually fruiting, though the heaviest push still comes with the fall rains. The first frosts around Oct 23 eventually close the main season, though hardy cool-season species hang on.
