Flagstaff Mushroom Calendar
Flagstaff sits in the Arizona/New Mexico Mountains and has a drier, rain-shadowed climate, with roughly 20.5 inches of annual rainfall. The ground warms and reaches early fruiting potential around May, though frost is still possible until about Jun 4. The main flush around Flagstaff follows the summer monsoon: after a dry June, the thunderstorms that build in July soak the high country and set off the year's biggest fruiting. Winter then shuts the season down hard and early.
