The Lowdown
Alright folks, Rusty here. Let’s break this down.
It’s a quiet stretch ahead, no two ways about it. The water’s a warm 84°, and the temperature anomaly is just 0.6°, so it’s pretty much what you’d expect for this time of year.
The only break we’re looking at is Trincomalee, a sheltered point that rarely breaks, and it’s a beginner-friendly wave. The first few days are a write-off. From Saturday the 8th of August through the 10th, we’ve got tiny surf, with heights around 1ft from the SSE, and the combined energy is weak, between 33 and 64. The wind is a steady cross-off from the WSW, keeping the surface clean, but there’s just no power in the water.
Tuesday the 11th brings a little change. Swell direction goes to the S, and the period stretches out to a very long 20 seconds, pushing the combined energy to 420 – that’s moderate energy. But the wave height is still only about 2ft. That long period at a point break like this is going to mean long waits and sleepy lines. The wind stays cross-off, so it’s clean, but it’s not enough to get the heart pumping.
Over the next week, we see a few pulses of that long-period S and SSE swell, with energy kicking up into the 100-200 range, but wave heights never get above 2ft. The wind stays mostly cross-off, keeping the surface tidy. The best chance for a paddle might be Wednesday the 19th of August, when we get a glassy morning with a light NW breeze of 3 mph, but the swell is only 1ft from the SE at 9 seconds. It’s clean, but tiny.
Bottom line? There’s really no standout session in the whole 16 days. This is a spot that rarely breaks, so a quiet run like this is pretty standard. The swell is small, and the wind never really lines up to make the most of it. I’d save your energy and keep an eye on the longer-range forecasts, but don’t hold your breath.
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.
