San Diego transitions into fall with an array of seasonal events, cooler weather, and outdoor activities as the region shifts away from summer temperatures. According to the San Diego Tourism Authority, the autumn months bring lower humidity and comfortable daytime highs that average in the mid-70s, making it a prime season for local festivals and coastal exploration.
Fall Weather Patterns and Temperature Shifts
Temperatures across San Diego County typically begin a noticeable downward trend in September and October. The National Weather Service notes that coastal areas experience average high temperatures around 75 degrees Fahrenheit, while inland valleys see slightly warmer conditions before cooling down significantly by November. This climate shift drives local residents and visitors toward outdoor recreation, including hiking in Torrey Pines State Natural Reserve and exploring Balboa Park.

Autumn in San Diego features several high-profile community events. The Gaslamp Quarter Association coordinates multiple historical tours and culinary events through the fall season. Meanwhile, regional harvest celebrations and pumpkin patches open across inland valleys such as Ramona and Julian, offering apple picking and seasonal agricultural tours.
Outdoor Adventures and Coastal Activities
Water temperatures along the coast remain mild enough for surfing and paddleboarding through October, according to local lifeguard reports. Fall also marks the beginning of the local whale-watching season, with migrating Pacific gray whales passing the San Diego coastline starting in mid-December. Hiking trails in Mission Trails Regional Park experience increased foot traffic as cooler morning temperatures replace the intense heat of mid-summer.
