SAN DIEGO, Calif. – Clear skies and mild temperatures will make this second weekend of October ideal for outdoor plans across San Diego County, with just a hint of cooler Fall air returning by Columbus Day. Families headed to pumpkin patches or the coast can expect classic Southern California sunshine before light clouds and a cooling trend begin early next week.
According to the National Weather Service in San Diego, high temperatures will reach the low 70s through Monday, with daytime breezes from the west keeping air quality and visibility excellent along I-5, I-15, and coastal parks. Monday brings a few more clouds as Pacific moisture nudges inland, signaling a subtle shift toward cooler, cloudier Fall conditions later next week.
Beachgoers and travelers planning holiday drives should stay hydrated and wear sunscreen, as UV levels remain moderate. Inland valleys, from Escondido to El Cajon, will stay comfortably warm, while the coastal strip enjoys calm seas and light surf under mostly sunny skies.
By Tuesday, light showers may brush the northern county foothills, but no major storm systems are expected. Residents can safely enjoy outdoor markets, hiking trails, and early Halloween decorating without concern for wind or rain disruptions.
Though mild, this weekend’s pleasant stretch marks the seasonal pivot toward crisper mornings and lengthening evenings — a sure sign that Fall in Southern California has arrived.
