Best Time of Year to Build a Pool in the San Francisco Bay Area
The best time to start a Bay Area pool project is late summer or early autumn, because permitting takes two to three months and November through March carries 82 percent of San Jose’s annual rainfall. Applying in August or September puts excavation ahead of the wet season and finishes the pool for the following spring. June through September average under a third of an inch of rain, which is ideal for building and too late for swimming.
