Traveller notes on Trincomalee in March
Trincomalee's forum calls March dry season on land, but flags the sea as the catch — one visitor was told by hotel staff not to go in past their knees until late April or May, when the rougher swell finally settles. Another had a genuinely sunny, trouble-free stay in mid-March, sea aside.
