The Lowdown
Alright folks, Rusty here. Let's have a look at what's in store for the Trincomalee area over the next couple of weeks.
Straight up, I gotta be honest with you – it's gonna be a tough stretch. The surf is going to be flat to tiny the entire 16-day window. We're looking at a long, dry spell with no real swell to speak of. The first record we have is for Sunday the 23rd of August, and from then right through to Monday the 7th of September, it's all the same story: small, weak waves.
The only break on the radar is Trincomalee itself, a point break that very rarely breaks. It's a sheltered spot, which is good for keeping it clean, but it's also part of the problem with these tiny swells. To get a wave here, we need a decent push, and that's just not happening.
Throughout the whole period, the swell is a measly 1ft to 2ft. The direction is mostly from the SSE or SE, which is actually the opposite of what this spot likes (it wants it from the south). The combined swell energy is pathetic, staying in the low double digits or barely cracking the 40s to 50s (we're talking 19 to 78). You'll see a few longer period swells on the 24th of August with an 18-second period, but even that only manages a combined energy of 53. It's a classic case of a long-period groundswell that just doesn't have any guts behind it.
The wind is a constant cross-off from the WSW, which will keep the surface clean, but there's nothing to push the wave face up. On the 29th of August (Saturday afternoon) and the 30th of August (Sunday afternoon), we get a brief window of proper offshore wind from the WNW and W, but it's still on a tiny, weak swell. It's like polishing a pebble.
There is no standout day here. This is a region where a blank run like this is not unusual. For a beginner, it's too small to even learn on, and for anyone else, there's just no wave. Honestly, with the wind howling at 19 mph most days and the surf being this small, the setup looks more interesting for kite surfing than paddle surfing. Don't hold your breath for any last-minute changes; it's just a run of bad luck.
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.
