The Lowdown
Right, let’s have a look at what’s on the table for Trincomalee over this 16-day stretch. I gotta be straight with you – it’s pretty grim. The guidance tells me this spot is a point break, sheltered as anything, and it rarely breaks. The finder backs that up entirely. We’re looking at a long, dry run with no real surf to speak of.
The first record kicks off on Thursday, the 27th of August. We’ve got a tiny 2 ft swell coming from the SE with a short period of 8 seconds. The combined energy is weak at just 40. Wind is a fresh cross-off from the WSW at 22 mph, so the surface is clean, but the waves are just too small and weak to do anything with. The comment says it all: “poor surf conditions.” This same flat, weak pattern drags on day after day. Every morning and afternoon through the end of August and into September shows the same story – 1.0 ft to 2 ft of SE swell, periods between 8 and 10 seconds, and wave energy values bouncing between 15 and 77. Winds are mostly cross-off, keeping the water clean, but there’s no power.
There is a brief moment on Monday afternoon, the 31st of August, where the wind goes glassy, going NNW at just 3 mph, and the water gets glassy. But the swell is still a pathetic 1 ft with only 19 of energy. It’s a pretty sight, not a surfable one.
The strongest energy we see all period is on Friday morning, the 4th of September, with a combined energy of 77 coming from a 2 ft SSE swell at 9 seconds. That’s still bottom-of-the-barrel. Even that small bump fades by the weekend.
We get a slight change around the 10th of September. On Thursday afternoon, the swell direction shifts to SSE with a 13-second period, which is a longer-period groundswell. It’s only 0.7 ft, though, and the energy is 48. That’s not going to break properly anywhere, especially at a sheltered point.
So, to put it plainly: there are zero recommended days in this 16-day window for Trincomalee. The spot is inconsistent at the best of times, and this forecast shows a prolonged flat spell. The water temp is sitting at 84°F, which is about normal for the time of year, but that’s about the only thing that’s normal. If you’re looking for something to do, this setup – small, weak swell with clean but persistent cross-off winds – is more interesting for a kite than a paddle. The fishing might be good, though. Forecasts can change, but right now, it’s a blank run.

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.
