Trincomalee & the east is in its dry stretch right now, February to September. This is the easy window: plan around sun and heat rather than around rain.
Going in May
Dry and settled while the southwest coast is under its monsoon. This is the whole point of knowing the two coasts apart: one island, opposite answers in the same month.
What this means for your bag
Real sun protection
High-factor sunscreen, a hat with a brim and sunglasses. Reef-safe sunscreen is worth buying before you go — it is expensive and hard to find at the beach.

Heat like this needs far more water than you think. A filter bottle also spares you buying a plastic bottle every two hours.

Cotton takes two days to dry in this air and starts to smell before it does. Synthetics and merino wash in a sink and are wearable by morning.

The hottest stretch, with afternoons around 34°C and very little cloud.
What this means for your bag
Loose, covering clothes
Long and loose beats short and tight in serious heat: it keeps the sun off skin and moves air. Linen and light cotton in pale colours.
