The Lowdown
Alright, folks, Rusty here. Let me tell you straight up, it’s a bit of a flat spell for the Trincomalee area. We’ve got a 16-day window ahead, but the first recommendation doesn't kick in until the 5th of August, and even then, it’s a tough sell.
The overall pattern is one of very small, weak swell and a lot of cross-offshore wind. The water temp is sitting at a warm 83°F, which is just about average for this time of year, so no surprises there.
The only spot we’re looking at is Trincomalee. This is a point break that rarely breaks, and it’s very sheltered. On the 5th of August, we’re looking at a tiny 0.3ft swell from the south with a period of 14 seconds. The combined energy is a weak 8. It’s just not enough to get excited about, and the forecast is calling for poor surf conditions. The wind is light and cross-off, which would be clean, but there’s nothing to ride.
As we move through the first week, the swell struggles to get above 1ft. The wind stays mostly cross-off from the WSW, with a few moments of true offshore wind on the 9th and 10th of August. Even then, with the swell barely hitting 1ft and a period of 11 seconds, the energy is moderate at best, with values like 54 and 64. It’s clean, but it’s just not surfable.
The second week sees a tiny bump. On the 11th of August, we get a 1.0ft swell with a very long period of 20 seconds, and the energy climbs to 138. That’s a proper groundswell, but it’s tiny. That long period will make it break super straight at a beach break, but this is a point break, so it might wrap in a little. Still, 1.0ft is a tough ask. The wind is cross-off, not ideal.
From the 12th of August onwards, the swell stays in the 1ft to 2ft range, with the best energy hitting around 160 on the 14th of August. The wind is consistently cross-off from the WSW, which is clean but not glassy. The crowd profile says "sometimes," so you might have company, but there won’t be much to fight over.
Honestly, there’s no standout session here. The surf is just too small. If you’re a beginner, the 1ft to 2ft days might be manageable, but it’s not going to be a fun paddle. The 2ft day on the 15th of August is the biggest, but with a period of just 10 seconds, it’s weak and short-period. The wind is a fresh cross-off, so it’ll be bumpy.
For a more experienced surfer, there’s nothing to get the heart pumping. The setup is more interesting for a kite surfer than a paddle surfer on those afternoons with a bit of wind and tiny swell.
So, to sum it up: we’ve got a long stretch of poor surf. Hold on to your boards, the forecast can change, but for now, it’s a lot of waiting.
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.
