Weligama Alert Guide

Southern Province, Sri Lanka · part of the Weligama spot guide

Weligama is forecast-only — no buoy within roughly 1,100 km — so this is a model-swell alert. The bay softens the swell substantially, so the height below reads larger than the gentle face you ride.

The forecaster's checklist

  1. 1.Check the season first — November to April is prime, dry and offshore, with January to March the sweet spot; the off-season still works but is smaller and more onshore.
  2. 2.Want swell from the south to southwest (about 180–225°); anywhere in the wider window enters the bay.
  3. 3.Favour 10-to-16-second long-period groundswell for the cleanest long rollers; short-period wind swell is weaker and messier.
  4. 4.Read the model height then mentally shrink it — the bay softens it to a learner face, and around 0.8-to-1.4 metres is ideal chest-high learner surf.
  5. 5.Want a north or northeast offshore, surf the morning before the sea breeze, and time your session before the surf-school rush.

Local winds & tide

Best wind: N–NE offshore (NE monsoon) — from 0° to 70° (N–ENE).

Surfable at all stages, which is part of what makes it beginner-friendly; lean mid-to-high for the softest, least closed-out rollers, and note the south coast is microtidal so tide is a secondary variable.
