The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ in our little corner of the world.
Alright, I gotta be straight with you. We are looking at a real tough stretch here. The swell window is pretty much shut for the next two weeks. The first hint of anything worth paddling for doesn’t show up until Saturday the 26th of September, and even then it’s a long shot.
Before that, it’s a flat spell. From now all the way through to the morning of the 26th, we’re looking at tiny waves – mostly around 0.3 ft to 2 ft – and the combined swell energy is weak, never cracking triple digits. There are a few mornings with clean conditions, like this Friday the 11th morning with a light cross-off breeze, but the waves are just not there. You’d be doing more floating than surfing. For the most part, the wind is a mix of onshore and cross-off, with some moderate breezes, so it’s not even good for a paddle. We’re talking about a solid 15-day gap of nothing to recommend.
Now, for the only blip on the radar, which is a long way out. On Saturday the 26th of September morning, we finally see a jump. The wave height comes up to 3 ft from the SSE, with a period of 10 seconds. The combined swell energy hits 209, which is a moderate energy reading, so there’s finally some push in the water. The wind is a stiff 22 mph from the WSW, which is a cross-off breeze, so the surface should be clean. This is at Trincomalee, a point break that’s sheltered and rarely breaks, so the fact it’s showing anything is notable. But the swell direction is from the SSE, which isn’t the optimum S direction the spot likes best. It’s a beginner-friendly wave when it’s on, but 3 ft is perfectly fine for all levels. The water temp is 84°F, which is about average for this time of year, nothing weird.
Honestly, this Saturday the 26th morning window is the only standout, and it’s a weak one. The swell is small, the period is average, and it’s over a week away, so don’t get your hopes up too much. The afternoon drops off again. The rest of the outlook is just more of the same flatness. If you’re desperate for a splash, keep an eye on that morning, but otherwise, this is a true dry spell.
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.
