The Lowdown
G’day, Rusty here, and I gotta be straight with you – this is a pretty bleak run for the region. The finder’s got nothing for us, so let’s have a look at what the guidance is saying. The only spot we’ve got to work with is Trincomalee, a point break that’s a beginner-friendly wave but it rarely breaks. That’s the first red flag right there.
Over the next 16 days, from Friday the 28th of August right through to Saturday the 12th of September, every single observation is flagged as "poor surf conditions." That’s a solid two-week gap with no real surf on offer. The swell is tiny, hanging around 1 ft to 2 ft, all from the SE, with a short period of just 8 to 10 seconds. The combined energy of all swells directed here is weak, sitting between 15 and 119 (119 is the only one that hits the moderate range, but it’s still not enough to get excited about). The wind is mostly cross-off from the WSW, which is clean, but it’s a bit strong at times, hitting 19 mph. The water temp is about 84° with a 1° anomaly – pretty average for this time of year.
For a break like Trincomalee that’s very sheltered and rarely breaks, you need a decent swell from the south to get it going, and we just don’t have that. The setup might look more interesting for kite surfing than paddle surfing, given the consistent cross-off breeze and tiny waves, but for a surfer, it’s a no-go. There’s not a single standout day here. The best you could hope for is a clean, glassy morning with the lightest wind, but even then, the swell is too weak to push through. It’s a blank run, and for this area, that’s pretty normal.
Hang in there, forecasts can change, but for now, I’d say leave the board at home.

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.
