Seaside Mushroom Calendar

Seaside sits in the Coast Range and one of the wetter corners of the region, with roughly 76.7 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 January, by which point the average last frost (Apr 2) has usually passed. Like much of the Pacific Northwest, summers around Seaside run dry, and flushes show up only sporadically where localized rain falls; the season picks up again in August with the return of autumn rains. The first frosts around Nov 12 eventually close the main season, though hardy cool-season species hang on.
