San Diego boasts a Mediterranean climate, which basically means it's mild and sunny most of the year. We're talking warm, dry summers and mild, wet winters.

This is super important to understand! For example, downtown San Diego might be a balmy 75°F (24°C), while Julian, up in the mountains, could be a cool 60°F (16°C). And guess what? The desert areas can be scorching hot, reaching well over 100°F (38°C) during the summer months. — The Inheritance Of Loss: A Deep Dive
