Anchorage Mushroom Calendar
Anchorage has a notably dry climate, with roughly 14.2 inches of annual rainfall. The ground warms and reaches early fruiting potential around May, by which point the average last frost (May 1) has usually passed. Summer fruitings stay confined to pockets of moisture — irrigated urban ground can be one — and the real abundance arrives with the fall rains in July. Winter then shuts the season down hard and early.
