What it feels like
Even in the same month, comfort often splits by “walking-heavy” versus “mostly indoors.”
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.
What people usually wear
Not a single “correct outfit”—just common choices that cover most situations.
- • 🛳️ Baseline: On the bay, deck wind can make it feel cooler than on land. The same day can feel hot inside and chilly on deck—layers help.
- • 🌞 Summer (May–Sep): Hot, humid, and showery. Quick-dry clothing, waterproof pouch, and spare tee/socks reduce the “staying damp” time.
- • 🌬️ Deck breeze: Even in hot months, deck time can feel breezy. A thin shirt/windbreaker helps adjust.
The same numbers can still feel different depending on how you travel.
