The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the Trincomalee area.
Honestly, I gotta be straight with you – this 16-day window is a tough one. We’re starting with a real dry spell. The first recommendation doesn’t even pop up until Sunday, the 9th of August, and even then, it’s a grim picture. For the next two weeks, the surf quality is rated as poor across the board, so we’re not dealing with any kind of classic run here. There are no standouts, no real highlights to get excited about.
The only spot on the radar is Trincomalee itself, a point break that’s a beginner-friendly wave but rarely breaks, so you’re already fighting the odds. The swell direction is coming from the SSE and SE, but the optimum swell for this spot is from the S, so the direction is a bit off. Swell heights are tiny, mostly hanging around 0.7 ft to 2 ft. The combined swell energy is weak, ranging from a measly 7 up to 135 (moderate energy) at best, but mostly sitting under 100. Those numbers tell the story – there’s just not enough push.
With such small, weak swell, the wind is the only thing that’s clean, with mostly cross-off breezes. You’ll get a few glassy moments, like Wednesday afternoon the 12th with a light offshore from the W at 6 mph, but the swell is only 1 ft – it’s a flat, clean pond. The water temp is a warm 83°, which is about normal for this time of year, so you won’t need a wetsuit, but you won’t need a surfboard either.
Because the swell is so small and inconsistent, and the break is a point, it’s not even worth talking about kite surfing. Just a long, quiet stretch ahead. The blank run is pretty normal for this area when the conditions aren’t lining up. Forecasts can change, but right now, it’s a waiting game.
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.
