The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for our stretch of coast.
Honestly, I’ve got to be straight with you – this is a tough one. The whole 16-day window is looking flat and pretty hopeless for a proper paddle. We’re looking at a long, dry spell with barely a ripple. The first real surf recommendation doesn't show up for a while, and even then it's tiny. There’s a long gap of nothing from the start of the period until the second week, with nothing to get excited about.
The only break that’s even in the picture is Trincomalee, a point break that’s rated for beginners but it rarely breaks, so don’t get your hopes up. The water temperature is sitting around 83°, which is about normal for this time of year, so at least a dip won’t be a shock.
For the first week, from Monday the 3rd of August right through to Sunday the 9th, it’s a write-off. We’re talking swell heights of 0.3ft to 1.0ft, with combined wave energy barely reaching double digits (like 4 to 82). The wind is a persistent cross-off from the WSW, which is fine for keeping the surface clean, but there’s just no swell to work with. It’s all poor surf conditions.
Things don’t really improve until we get into the second week. Around Monday the 10th of August, we finally see a slight bump. The swell bumps up to 1ft from the SSE, and the combined energy is starting to creep up – 60 on Monday afternoon. The wind goes light offshore from the west at 9 mph, making for some gentle offshore and clean conditions. It’s still tiny, but for a longboard or a learner, you might find a knee-high wave.
The best of a bad bunch looks like it’ll be on Saturday the 15th of August. We’ve got a 2ft swell from the SSE, with a period of 11 seconds, and the combined energy hits 110 (moderate energy). The wind is still a cross-off, so the surface will be clean. It’s not going to be a classic, but for a point break that barely works, this is your best shot. The swell direction from the SSE is a bit off from the optimum S direction for the break, but it’s the biggest we get.
After that, we drift back into tiny, weak surf for the rest of the window with energy dropping back under 100. The very last day, Tuesday the 18th of August, shows a brief moment of glassy conditions in the afternoon with a light NE wind at 3 mph, but the swell is only 1ft.
It’s a grim outlook, to be honest. But these things happen. It tends not to stay this flat forever, and forecasts can change, so keep an eye on it. For now, leave the board in the shed.
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.
