The Lowdown
Alright folks, Rusty here. Let’s be straight with you about Trincomalee. This is a tough one. The whole 16-day window is a flat spell for the region. There’s simply nothing to get excited about, and I’ll be honest with you – it’s probably going to stay that way for a while.
The first record we’ve got is for Tuesday, the 8th of September, but it’s just a tease. The swell is a tiny 2ft from the SE, with a period of 8 seconds, and the combined energy is a weak 83. The wind is a cross-off from the SW, but the conditions are just poor. The wave energy is too weak to really do anything with. The water temp is a balmy 84°, which is about average for this time of year, so at least the water is nice for a swim.
The only break on the books is Trincomalee itself. It’s a point break, but it's a rare one – it rarely breaks, and this forecast confirms why. It’s very sheltered and the swell just isn’t pushing in. The optimum swell direction is from the south, but the tiny, short-period SE and SSE swells we see are just not enough to wrap in properly. On Wednesday the 9th, the swell height bumps to 3ft, and the energy climbs to 169, but with a period of 9 seconds, it’s still just a weak, crumbly wave. The Wednesday afternoon wind does turn offshore from the WNW, which is always a positive sign, but there just isn’t enough swell to make it worth paddling out.
The rest of the forecast is a long, drawn-out gap. Day after day, we see the same story: swell heights between 0.7ft and 2ft, periods from 8 to 10 seconds, and combined energy that drops from a moderate 110 to a pathetic 9. The wind is mostly a cross-off from the WSW, which is not ideal for this spot. Even on the 23rd of September, when the swell climbs back to 2ft, the energy is only 59 and the period is a short 8 seconds. There’s no punch, no power.
This is a tough reality for this area. When the swell is this absent, the inconsistency of Trincomalee really shows. It’s a beautiful spot, but for the next couple of weeks, the only thing you’ll be riding is a flat spell. The forecasts can change, but for now, give the board a rest.
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.
