The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you – the surf outlook for Trincomalee over the next couple of weeks is a bit of a write-off. There’s just no proper swell on the table, and that’s a tough one to swallow. The whole 16-day stretch is a blank run, with nothing that I’d call a recommendation.
So what’s going on? Trincomalee is a point break that rarely breaks and is very sheltered, so it takes a specific combination to fire. We’re looking at a long stretch starting from Saturday the 15th of August right through to Sunday the 30th of August, and it’s all poor surf conditions. The combined swell energy is weak, sitting under 100 (values range from a feeble 6 up to just 65), which tells you there’s no power in the water. Swell heights are tiny, mostly 0.7 ft to 2 ft, coming from the SE, which is the optimum direction, but the period is short – often 8 to 10 seconds – so there’s no grunt.
Now, I know this spot is inconsistent, so a quiet run isn’t out of the ordinary. The wind is mostly cross-off from the WSW, moderate to fresh breeze (9 to 22 mph), which keeps the surface clean, but without any size, clean doesn’t matter. There is one moment that catches the eye: on Sunday the 30th of August afternoon, we get some clouds and a glassy wind from the north at just 3 mph, with the swell nudging up to 2 ft from the SE at a 9-second period. The combined energy hits 65 (still weak), but glassy conditions on a rare-breaking point break in the afternoon is the closest thing to a standout on offer. For the advanced surfer who knows the spot and can make the most of a small, clean wave, that afternoon *might* be worth a look.
The water temperature is around 84°F, which is about normal for this time of year, with a slight positive anomaly of 1°F.
Bottom line: for the next two weeks, you’re better off doing something else. That Sunday the 30th afternoon glass-off is the only whisper of hope. Keep an eye on the charts – this area can change. Stay tuned.
Rusty.

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.
