The Lowdown
Alright, I’m Rusty, and I’ve got to tell you, the outlook for the Trincomalee area is a tough one. We’re looking at a full 16-day window, but the surf is basically a no-show for the first week and a half. The only spot that ever gets a sniff of swell, Trincomalee, is a point break that’s "rarely breaks" for a reason, and it’s proving it right now.
From the 29th of July all the way through to the 10th of August, it’s flat. The swell is a joke, bumping around 0.3 to 0.7 feet from the SE, and the combined wave energy is pathetic, stuck in the double digits (like 12 to 118). The wind is a steady cross-offshore from the WSW, blowing at 18 to 22 mph. Even though the reports say "clean," the waves are just too small to paddle for. It’s a total write-off.
Then, on the 11th of August, we get a glimmer. The swell picks up to 3 feet on Tuesday afternoon, with a long period of 12 seconds. That’s a real groundswell, and the combined energy jumps to 198, which is a moderate reading. The wind eases to a moderate cross-off (12 mph), so the surface should be glassy. For a point break, that long period SE swell could wrap in and offer a few decent, rideable waves. The 12th of August looks similar, with a 3-foot swell and 11-second periods, but the wind kicks up to 22 mph, making it a bit of a fight.
So, the only real window to get wet is the 11th and 12th of August. The swell is still small, but it’s the best of a bad run. The water temperature is about average for the time of year, so nothing crazy there. The 11th of August Tuesday afternoon is the pick of the whole forecast—biggest swell, longest period, and cleanest conditions. After that, it drops off again on the 13th. It’s a long wait for small rewards, but it’s the hand we’ve been dealt.
Keep your eyes peeled, but don’t get your hopes up too high.

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.
