What it feels like
Rain changes how you move, and wind makes the same temperature feel much harsher.
When it tends to fit
- • If you’ll walk a lot and you’re sensitive to wind or rain, cooler/drier conditions tend to fit better.
- • For photo-and-walk trips, sunny days usually matter more than the exact temperature.
When it may not fit
- • If you struggle with humid heat, some seasons can feel tiring even when the numbers look similar.
- • In rainier periods, “walking as planned” can be harder—tight itineraries may not fit well.
- • If you do many night outings, evening wind and chill can matter more than daytime highs.
What people usually wear
Not a single “correct outfit”—just common choices that cover most situations.
- • 🧭 Key idea: San Diego is mild overall, but coastal (cool/marine layer) vs inland (hotter) differences matter. Your itinerary location often decides what feels right.
- • 🌧️ Winter (Dec–Mar): rain can arrive in clusters. A light jacket + layers and a rain option are practical.
- • 🌫️ May–June: marine layer can bring cool, cloudy mornings—thin layers help even when afternoons are warm.
The same numbers can still feel different depending on how you travel.
