The Lowdown
Alright, Rusty here. Let's be straight with you – the next 16 days are looking flat for Trincomalee. The wave energy is just pathetic, readings between 17 and 88 for the whole run, which is about as weak as it gets. We're looking at tiny, weak swell from the SSE and SE, mostly around 1.0ft to 2ft and short periods under 11 seconds. There's no real punch, no power, and honestly, nothing to get excited about.
This is a rarely breaks point break, and it's living up to that name right now. The winds are mostly cross-off from the WSW, so the surface will look clean, but with no waves to ride, clean conditions don't matter. The combined swell energy for the whole period is weak and under 100. On the 21st of August morning, we do see a 14-second period from the S, but with a tiny 1.0ft and fresh 19 mph winds, it's still just poor surf.
For the first week, from August 13th through the 19th, the swell stays below 2ft. Even the afternoon of the 15th offers a brief moment of offshore wind from the WNW at 6 mph, but the swell is still only 2ft from the SE. It's not enough to surf.
There's a gap of nothing from the 20th morning right through to the 28th evening. The swell barely scratches 2ft again by the 26th morning, producing a combined energy of 85 – still weak and not worth paddling out.
If you're looking for a silver lining, the thermal anomaly isn't mentioned in the data, so the water is about average for this time of year, but that doesn't help when there's nothing to ride. For beginners, the swell never gets above 5ft, so it's not dangerous, but it's also not rideable for anyone.
This is just how it goes here sometimes. A blank run is normal for this area when the conditions don't line up. Forecasts can change, but for now, leave the boards at home.
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.
