The Lowdown
G’day, I’m Rusty, and I’ve got the local skinny on what’s coming up. Let’s be straight with each other – it’s a flat spell right now and it’s going to stay that way for a long stretch. There’s nothing worth paddling out for in the entire 16-day window. The only spot in the mix is Trincomalee, a point break that’s a beginner-friendly wave, but it rarely breaks. The swell direction is SE, but this spot is very sheltered and really wants swell from the S. The water’s sitting at 84°F with a normal temperature anomaly, so nothing unusual there.
Right now, from Thursday 27 August through to Friday 11 September, every session is rated as poor surf conditions. The swell is tiny – mostly 1.0 ft to 2 ft – with a short period around 8-10 seconds, so there’s no push or power. The combined energy is weak, sitting between 20 and 131 (131 is the highest, but still only moderate at best). The wind is mostly cross-off from the WSW, which keeps the surface clean, but that doesn’t matter when there’s nothing to ride. There are a couple of glassy moments on the morning of Saturday 5 September, but the swell is still just 2 ft. It’s just not happening.
This is a tough run for the area. With a break that’s inconsistent and a flat outlook, I’d say don’t hold your breath. The forecasts can change, but right now, there’s no surf to chase.
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.
