Excerpt from Destination Temecula
Temecula Valley enjoys a wonderful microclimate created by a location sandwiched between the Salton Sea in the Anza-Borrego Desert to the east and the Pacific Ocean to the west. The Salton Sea is generally the lowest pressure area in California and it pulls air from the Pacific Ocean, a high-pressure area.
As warm air rises from the desert floor each day, it acts as a vacuum and our valley receives moisture-laden afternoon wind gusts peaking at 15-20 mph through an 18 mile gap in the western hills from the ocean, creating cool mornings and evenings which bookend intense mid-day sunshine.
