The Lowdown
Alright crew, it's Rusty here, and I've got to be straight with you – the outlook for our region over the next couple of weeks is a tough one. We're looking at a long stretch with nothing really worth paddling out for, so don't be busting the board bags out just yet.
The first proper surf recommendation doesn't come up until now, and looking at the data, the whole stretch from now through to the end of the first week is a write-off. We're talking 16 days of poor surf conditions. That's a big gap with no recommendations at all – a proper lull.
Let's talk about the only named break we've got: Trincomalee. It's a point break, really sheltered, and the guidance tells us it "rarely breaks," which is a massive caveat. The water temp is sitting at 84°F with the anomaly just over a degree, so about what you'd expect for this time of year.
From the start of the forecast right through to early September, it's all tiny 1ft to 2ft swell, mostly out of the SE or SSE with a short period of only 8 seconds to 11 seconds. That's weak, short-period wind swell with barely any energy. The wave energy values are all two-digited (17 to 90), confirming how weak it all is. On top of that, the wind is a cross-off breeze from the WSW, mostly a fresh breeze at 15 to 18 mph. The data labels it as "poor surf conditions" every single day, with a score of zero. This setup would honestly be more interesting for kite surfing than for a paddle session.
Even towards the very end of the second week, around the 3rd of September, the swell nudges up to 2ft with a slightly longer period of 11 seconds. The energy gets to a top of 90, still just moderate. While the period is a bit better, the wind is still fresh and cross-off, and the spot "rarely breaks" anyway. It's not enough to get excited about, especially that far out.
So, here's the grim truth: there are no standouts. Nothing is firing, nothing is clean. For this area, a blank run like this is unfortunately normal. Forecasts can change, but for now, keep your wax dry and don't hold your breath.
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.
