The Lowdown
G'day, Rusty here.
To be straight up with you, mate, the next 16 days look flat as a tack around here. There's just no energy to get excited about.
Starting from August 12th, we're looking at Trimcomalee, and honestly, it’s a struggle. It’s a point break that rarely breaks, so this is kind of expected. The swell is tiny, hovering around 0.7ft to 2ft, and the combined energy is weak, reading between 20 and 100 for the whole run. Winds are mostly cross-off or cross-shore, and while conditions look clean on the surface, there's just nothing pushing in. It’s a beginner-friendly spot when it goes, but with these numbers, even a learner would be wasting their time. The water temperature is about average for the time of year, so at least you won't freeze while you're sitting there.
We get a little flutter on August 20th with a long period swell (16 seconds) coming in from the south, but it's only 0.7ft. That Thursday afternoon goes glassy with almost no wind, which would be beautiful if there was any wave to ride. August 22nd Saturday afternoon has the biggest read of the whole period at 3ft, with a short 7-second period from the SSE and moderate wave energy (98), but it's still poor surf.
Honestly, there's no standout here. If you're desperate for a paddle, the clean windows on August 15th Saturday afternoon with a light breeze from the NW, or August 18th Tuesday morning with a gentle breeze, might be the least uncomfortable. But as for actual surfing? Save your energy. The forecast could change, but for now, this is a proper dry spell.
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.
