Rain season
Jaffna in northern Sri Lanka is dominated by the northeast monsoon (October–January), which delivers the bulk of its modest 1,000mm annual rainfall. The southwest monsoon largely bypasses the north, leaving summers hot and dry — some of the driest conditions in the country. Pre-monsoon heat in April–May is intense, frequently exceeding 36°C, before the northeast rains bring relief.
