The Lowdown
Alright, I’ve been staring at the charts for your neck of the woods, and I gotta be straight with you – it’s looking pretty flat out there, my friend.
The whole 16-day window is a bust. There's not a single day where you’d want to paddle out. From September 9th all the way through to the 24th, we’re stuck with tiny, weak surf that’s barely a ripple. The combined wave energy is pathetic, constantly in the double digits or low triple digits, like a measly 118 (moderate energy) at best, but mostly it's below 100 (weak energy). The swell direction is from the SE, which is all wrong for a spot like Trincomalee that needs something from the south.
For a place like this that “rarely breaks” anyway, this kind of dry spell is a bit more normal. But it’s frustrating when the wind is often clean or cross-offshore – the conditions *look* good, but there’s just no power to work with. The water temp is sitting around a very warm 84°F, which is about average for this time of year, so at least you’d be warm while you’re floating around doing nothing.
Don't get your hopes up. The only real standout here is the lack of any standout. Honestly, your safest bet is to wax up the kiteboard if you have one, because this setup is more interesting for kite surfing than paddle surfing. The fish are probably having a laugh at us.
Keep checking back, mate. The ocean can be a fickle beast, but it tends not to stay this quiet forever. Forecasts can change.

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.
