Quick answer

Up to 80% of UV passes through clouds, so a grey rainy day in Dhaka still ages and darkens your skin. The monsoon problem is that sweat and rain wash sunscreen off — so you need a light, water/sweat-resistant SPF50 and you need to reapply.
What to look for
- SPF50+ PA++++, labelled water-resistant or sweat-resistant.
- A light gel / fluid / "watery" texture — heavy creamy sunscreens feel awful and clog pores in humidity.
- No white cast, quick-absorbing.
