How it tends to feel for travel
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.
- • 🧩 Key idea: at high altitude, **day–night swings** are the main comfort factor. Warm sun and cold evenings can happen on the same day.
- • 🧥 Layering is the default: thin layers (long sleeve + hoodie + wind layer) work best.
- • 🌧️ Wet season (roughly Nov–Mar): frequent short heavy rain—rain protection and grippy shoes help.
Once you lock in a couple of constraints, the decision gets much easier.
