The Lowdown
Alright, let’s get real about Trincomalee. This is a very sheltered point break that’s listed as "rarely breaks," and looking at the entire 16-day window, it’s pretty much a flat spell. The swell is tiny across the whole run – we’re talking 0.7 ft to 3 ft, mostly from the southeast, with a period of just 8 to 10 seconds. That’s weak, short-period windswell, and the combined energy is mostly in the teens to sixties (27 to 68 range), which is weak energy. The only exception is on the afternoon of Monday, 14th September, when it bumps up to 3 ft and the energy hits 115 – still on the low end of moderate.
The water temperature on Sunday afternoon, 30th August, is 84°F with a slight anomaly of +0.9°F, which is about average for the time of year.
Now, for the good news – or lack of it. The entire forecast is marked "poor surf conditions" with a score of 0 out of 10. There’s no standout session. Even the morning windows are clean with cross-offshore winds from the west-southwest, but the swell is just too small and weak to be rideable. The optimum swell direction for Trincomalee is south, and the swell is coming from the southeast – close, but not quite right. The wind is often cross-off, which would be good for shape, but with no swell to work with, it’s a non-starter.
If you’re a beginner, this is a dead period. The swell is never above 3 ft, so it’s not too big, but it’s just not there. The afternoon of Saturday, 12th September, has a fresh breeze from the west at 19 mph and clean conditions, but still only 2 ft of swell. The afternoon of Sunday, 13th September, has a very long-period 17-second swell from the south, but it’s a tiny 0.7 ft. That long period means it would be clean and powerful for its size, but at 0.7 ft, you’re not surfing anything.
Honestly, this is a 16-day blank. The breaks are "rarely breaks" and the data shows no surf. For kite surfers, the afternoon of Sunday, 13th September, with a fresh 22 mph west wind and clean conditions, might be more interesting than paddling. But for a surf, there’s nothing to get excited about.

Information about the Trincomalee Surf forecast
The above surf forecast table for Trincomalee provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trincomalee can be found by selecting the local surf guide option on the grey menu. Our Trincomalee surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Trincomalee) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Trincomalee may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
