Long Beach Mushroom Calendar

Long Beach sits in the Coast Range and one of the wetter corners of the region — about 78.5 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 April, by which point the average last frost (Apr 6) 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 26 eventually close the main season, though hardy cool-season species hang on.
