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.
