How it tends to feel for travel
Rainier seasons can feel heavier even at similar temperatures, simply because you spend more time damp or under clouds.
For travel, what you remember is often variability (rain patterns, humidity, daily swings), not the average.
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.
- • 🌡️ 15-20℃: Feels like early summer or mild spring. Light long sleeves or shirts with a thin outer layer are usually enough.
- • 🌡️ 20-25℃: Short sleeves + light shirt or cardigan are perfect. Sea breeze can feel cool after sunset.
- • 🌡️ 25-30℃+: Classic resort weather. Pack full summer outfits—T-shirts, tanks, shorts, dresses.
It looks simple on paper, but the day-to-day texture can vary.
