North Bend Mushroom Calendar

North Bend sits in the Cascades and one of the wetter corners of the region, with roughly 63.3 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 March, by which point the average last frost (Mar 30) 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 Nov 7 eventually close the main season, though hardy cool-season species hang on.
