The Lowdown
Alright, I've looked at the charts for this stretch, and I'm not gonna sugarcoat it—it's a real bummer. The next couple of weeks look totally flat for surf.
The main break around here is Trincomalee, a point break that's good for beginners. It's a very sheltered spot, so it needs a real specific swell to get any juice. It's one of those spots that rarely breaks, and that's the story for the next 16 days. From Thursday afternoon, August 20th, all the way through to Friday, September 4th, the models are painting a picture of poor surf conditions. The swell is tiny, with heights barely hitting 2ft, and the combined energy of all swells is weak, never getting past a reading of 42, mostly just sitting in the teens and twenties. It's flat.
The wind is a constant cross-offshore from the WSW, which is a clean wind direction, but with no swell to work with, it's useless. The water temperature is around 84°, which is about average for this time of year, so at least you won't be cold while you wait.
The only tiny glimmer of hope is way out there on Monday, August 31st. The afternoon shows a shift to a light offshore breeze from the WNW and a slight bump in the swell to 3ft from the SSE. The combined energy jumps to 177, which is still weak, but it's the best we've got. That's more than a week and a half away, so don't get your hopes up. The rest of the forecast is just flat and disappointing.
There's a long stretch of nothing here. This area is known for spells like this, where the ocean just shuts down. For a few days around the end of August and start of September, the energy creeps up slightly, but the swell heights are still under 3ft, and the wave comments are all "poor surf conditions." You'd have a better time watching the kite surfers, because with these clean cross-off winds and tiny waves, that's the only thing that might get moving.

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.
