Galle is southeast from HIKKADUWA and is the most interesting colonial town in the area. You would find good left breaks near the jetty just outside of town,but doesn't work very often.
A bit further east is Kogalla, where reefs here don't pick up much swell, but when it's on, the left is excellent.
Midigama is a small village further east, which is less consistent than HIKKADUWA and more exposed to south winds. There are two spots: a long fat left and a short power full right breaking over a shallow reef. Conditions here are far more primitive than HIKKADUWA but far less crowded, inviting many surfing fanatics.
The beach brake in Weligama can be surfed even when small and the rest of the south coast is blown-out.
The same swells that turn Indonesia on, deliver the goods to SriLanka, although the higher latitude causes some swell decay. The main problem is that the most consistent SW swell season (April-October) will be accompanied by frequent SW rain. It is still possible to surf in the morning but expect rain, dirty water and strong winds with the 1-2.6m swells. This is the ideal time to travel to the south-easterly coast around ARUGAMBAY.
The best time for surfing in the south coast is at start and end of the dry season (November-April), when NE winds are most likely to coincide with the bigger SW ground swell.
During the dry season, waves are typically 0.6-2m and clean, so it's rare to see it totally flat in HIKKADUWA at any time of the year. Even during the NE monsoon, the afternoons tend to have some rain. The south wind affects the spots east of Galle far more than the HIKKADUWA breaks.
