The Lowdown
G’day, Rusty here. Well, I’ve got to be straight with you—this is a tough one. Looking at the whole 16-day window, there’s just nothing going on at Trincomalee. The swell is tiny, under 3ft basically the whole time, mostly from the SSE or SE around 8 to 11 seconds, which is short period and weak. The combined swell energy barely cracks 200 (202 is the highest on the 26th of July afternoon), and most of the time it’s sitting in the weak 30 to 100 range. That’s just not enough to get excited about.
The forecast says “poor surf conditions” for every single session right through to the 4th of August. You’re looking at a solid two-week stretch with no real surf on offer. The winds are mostly cross-off or cross from the WSW, which isn’t terrible, but with no swell to push, it’s a non-starter. On the 29th of July afternoon, there’s a brief window of light offshore from the W, but again, the swell’s only 2ft with a 9-second period—just not enough to make it worthwhile.
Trincomalee is a point break, it’s rarely breaks, and it’s very sheltered. This kind of blank run is actually pretty normal for the area when the swell direction isn’t cooperating. For beginners, even the tiny stuff might be manageable, but the quality is so poor it’s not worth paddling out. There’s nothing here that’s any good for anyone.
Keep an eye on the charts, because it tends not to stay this flat forever. But for now, leave the boards in the shed.

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.
