How it tends to feel for travel

In hotter periods, day-versus-night fatigue accumulates differently, changing how the climate feels.

When it tends to fit

  • Once you see the year-round pattern, it’s easier to judge whether a month fits your style.
  • If you revisit the city, separating “seasonal itineraries” can save a lot of planning time.
  • In humidity- or rain-driven cities, adjusting the indoor/outdoor ratio can change comfort a lot.

When it may not fit

  • If you rely only on averages, you may be surprised by variability (squalls, wind, indoor AC).
  • In monsoon-like periods, the more your itinerary depends on outdoor walking, the higher the risk.
  • If you’re fine with cold but hate damp chill, it can feel colder than you expect.

Outfit notes

This connects climate patterns to packing—without over-interpreting.

  • 🌡️ 5-10℃: A long padded coat or thick wool coat + knit/hoodie is ideal. Winter winds can be strong, so scarf and gloves help you enjoy night views without freezing.
  • 🌡️ 10-18℃: Light knit or sweatshirt + trench coat or short padded jacket works well. Days are mild but evenings can be chilly, so easy on/off layers are key.
  • 🌡️ 18-25℃: Short- or long-sleeve T-shirt + light outer (shirt, thin jacket) is usually enough. Air-conditioning on trains and in malls can be strong, so a cardigan is useful if you get cold.

In the end, it often depends on one or two conditions you care about most.
