Trout Lake sits in the Cascades and has a moderately damp climate — about 29.8 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, though frost is still possible until about May 18. Through summer, localized storms can set off scattered fruitings, but widespread flushes are rare until more consistent rain returns in October. Winter then shuts the season down hard and early.
