The Lowdown
Alright, Rusty here, and I’ve gotta be straight with you – this one’s a tough pill to swallow. For the next 16 days, starting right now on the 8th of September, through to the 23rd, there’s not a single session worth paddling out for at Trincomalee. The whole forecast window is one long, flat gap. Every single day comes back with a 0 out of 10 score. It’s a total bust, mate.
Look at the numbers: swell heights barely nudge above 2 ft or 2 ft, with a few afternoon spells dropping to 0.7 ft. That’s knee-high dribble at best. The combined swell energy is weak across the board, mostly in the 20s to 60s range (low energy), with only a few afternoons hitting three-digit figures – like Wednesday 9th afternoon with 164 (moderate energy) and Thursday 10th afternoon with 107 – but even then, the conditions are rated poor. The swell is coming from SE or SSE, which is not the optimum S direction this break needs, and the wind is mostly a cross-off from the WSW, which is actually okay, but it just can't make up for the lack of real swell.
This point break is famously inconsistent and only rarely breaks. So honestly, a blank run like this is pretty normal for the area. Given the small swell, cross-off wind, and beach/reef setup, honestly, if you're looking for a thrill this week you might be better off looking at kite surfing than trying to paddle out.
Water temp is sitting at a warm 84° F right now, which is about average for the time of year – no surprises there.
Look, there's no standout session, no hidden gem. Sometimes it just stays flat for a while. Forecasts can always change, but for now, keep the boards in the car and go for a swim instead.

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.
