Nevada City sits in the Sierra Nevada and has one of the wetter climates in the region — about 62.3 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 March, though frost is still possible until about Apr 14. Summer dries out — June through September typically see under an inch of rain — and fruiting goes quiet until the rains return in October, kicking off the year's main flush. The first frosts around Nov 20 eventually close the main season, though hardy cool-season species hang on.
