The Lowdown
Hey, it’s Rusty again. Same story, different numbers. This whole 16-day stretch for Trincomalee is looking weak. Wave heights are tiny—barely up to 2 ft, with the biggest days hitting maybe 2 ft at most, but still unrideable. The swell energy is nothing to write home about, reading as low as single-digit values up to just over 100 in combined energy. The currents won't be a problem because they won't exist.
From the start of the run, right through the first week of September, the swell is tiny (around 1 ft), with a short period, so it's just slop. Winds are mostly cross-off from the WSW, keeping the surface clean, but with no size or power, it’s just a flat, pretty lake.
Around the 6th of September, the period lengthens a touch, and we get a minor bump in energy (peak of 103), but heights are still just 1–2 ft, and the forecast still calls it “poor surf conditions.” That’s the highlight—which says a lot.
Trincomalee is a rarely-breaking point break, so a long flat spell like this is actually pretty normal for the area. There’s no surf to recommend for the next couple of weeks. The water's warm enough, but there's nothing to ride. If it stays like this, you're better off just enjoying the beach. Things can change, but right now? Nada.
Rusty out.

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.
