The Lowdown
Alright folks, Rusty here with the imperial take. This 16-day outlook is a dud. No real waves to speak of.
The only spot in the mix is Trincomalee, a point break that "rarely breaks" – and the data backs that up. The combined swell energy is a weak 32 on Saturday morning, August 29th. Water temp is a balmy 84°F, just about average for the season.
From Saturday, August 29th, all the way to Sunday, September 13th, it’s all "poor surf conditions." Swell heights are tiny, topping out at just 2ft, and it’s coming from the SE, not the preferred S direction. The period is short, 8-9 seconds, so no oomph. Winds are cross-off from the WSW, keeping it clean, but with waves this small, there’s nothing to ride.
No standouts, no swell, no hope. A long, flat spell like this is pretty normal for Trincomalee. It’s a quiet spot, and it’s in a quiet mood.
Keep the wax on the shelf.

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.
