The Lowdown
Ay, what’s happenin’? Rusty here. Lookin’ at the charts for this part of the world, and I’ve got to be straight with you—it’s a grim stretch. We’re staring down a 16-day window with practically no surf to speak of. The first record kicks off on Friday the 11th of September, but don’t get your hopes up.
The only spot on the radar is Trincomalee, a sheltered point break that rarely breaks. That alone tells you we’re in a tough spot. The water temp is a balmy 84°F, which is about normal for the time of year, nothin’ special.
From Friday the 11th right through to Saturday the 26th of September, every single session is rated as poor. The swell is tiny—mostly 2ft and dropping down to 0.7ft and 0.3ft later on. The combined swell energy is weak throughout, starting at a paltry 80 (weak energy) and falling to single digits like 8 or 10 by the middle of the period. The swell direction is mainly from the SE, but the optimum for Trincomalee is from the S, so it’s not even lining up right.
There are a couple of moments of glassy or very light offshore wind—like Saturday morning the 12th (SSE 0 mph, glass) and Tuesday morning the 15th (WNW 3 mph, glass)—but even then, the swell is so weak and the break rarely works, it’s not worth paddling out. For a point break, the longer period stuff (like 18 seconds on Wednesday the 16th afternoon) might sound fancy, but with only 0.3ft, that’s just a ripple.
Honestly, this is a blank run for the area. Trincomalee is inconsistent at the best of times, so a long stretch of no surf isn’t unusual here. I wouldn’t bother waxin’ the board for the next two weeks. Keep an eye on it—forecasts can change—but for now, it’s a write-off.
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.
