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.
- • If you want to keep fatigue low (kids/family trips), avoiding peak midday heat helps.
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.
- • 🌡️ 15–20°C (mornings/nights in Nov–Feb): It can feel surprisingly cool. A light hoodie, cardigan, or windbreaker is strongly recommended.
- • 🌡️ 21–28°C (daytime in the cool dry season): Comfortable for sightseeing—T-shirts, light long sleeves, and casual pants/shorts work well.
- • 🌡️ 29–35°C (hot season in Mar–Apr): Midday heat rises quickly. Wear breathable summer clothes and bring strong sun protection.
The same numbers can still feel different depending on how you travel.
