Weligama Surf Season
Southern Province, Sri Lanka · part of the Weligama spot guide
Sri Lanka has two monsoon-driven surf seasons that are opposite by coast, and the south-southwest coast — Weligama — is best roughly November to April, the dry, offshore season, driven by Southern and Indian Ocean south-to-southwest groundswell while the northeast monsoon keeps south-coast winds offshore. January to March is the most consistent, cleanest, driest stretch. It works year-round — even in the May-to-October off-season it produces smaller, mellower learner waves — but that off-season is the east coast’s (Arugam Bay) season instead.
Where the swell comes from
Deep South Indian Ocean and Southern Ocean groundswell from the roaring-forties latitudes for the primary long-period south-to-southwest swell, plus smaller local wind swell during the southwest monsoon off-season.

Dry-season south-coast regime
The documented pattern is the recurring November-to-April season, cleanest January to March, when the northeast monsoon grooms consistent south-to-southwest groundswell — a small, gentle wave with little big-swell lore rather than a single headline day.
