The Lowdown
Alright folks, Rusty here. Let's have a look at what Trincomalee has got cooking for us. I gotta be straight with you, this outlook is a tough one. We're looking at a pretty quiet run with no real standouts to get excited about, so temper those expectations.
The main issue is that this spot "rarely breaks" and it's very sheltered. For the entire 16-day window, the swell is tiny, barely a ripple most days. The combined wave energy is weak for the majority of the time, with readings mostly under 100, though we do see a few days where it bumps up into the moderate range, like 161 on the afternoon of Sunday the 9th. But even then, the swell heights are barely 1ft. That's not surf, that's a gentle bob. The wind is a constant cross-off from the WSW, which keeps the water clean, but there's nothing to ride.
The only faint glimmer of something slightly different comes on the weekend of the 15th and 16th of August. On Saturday afternoon the 15th, we finally see a little offshore wind from the WNW, and by Sunday afternoon the 16th, we get a light offshore from the west. The swell is still tiny at 2ft, but with that glassy wind, it'll be as clean as it gets. For a longboard or a foiler, you might catch a few knee-high lumps. But for anyone looking for a proper wave, it's a non-event.
Look, for the whole stretch, there's just no swell. This is pretty normal for an area this sheltered when it's not getting the right angle. Don't expect any waves worth paddling out for. If the wind is howling and you're desperate, maybe a kite would get you moving on that 2ft bump on the 15th, but for a paddle surfer, this is a blank run.
Rusty, signing off.

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.
