The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – the next 16 days for this area are a total write-off for any kind of decent surf. There’s not a single recommendation on the table from now through to the 9th of September. That’s a long, flat gap. Sometimes this region just goes quiet, and this is one of those times. Don’t lose hope though; these runs never last forever and forecasts can shift.
The only spot on the radar is Trincomalee, a sheltered point break in Sri Lanka that only rarely breaks. Water temps are sitting around 84°, which is about average for this time of year with a minimal anomaly of 1°.
For the whole three-week window, the swell stays tiny – just 0.7ft to 3ft from the south or south-southeast. The period is mostly short at 8 seconds, which means weak, shapeless energy. The combined energy is weak, ranging from just 16 up to 104 – that’s barely a ripple. Winds are mostly a moderate to fresh cross-off from the west-southwest, keeping the surface clean but doing nothing for the lack of waves. There’s one afternoon, Saturday the 29th of August, that flirts with a light offshore from the west, but with only 1ft of swell it’s still a flat, frustrating paddle. For what little swell there is the direction is south-east, when this point really needs a solid southerly groundswell to work. Even as we move into early September the swell nudges up to 2ft to 3ft with a period of 9 seconds and energy finally hitting triple digits (104 on the 9th), but it’s still too small and weak to get excited about.
Honestly, with these conditions – minimal swell, poor quality, and a beach-and-reef setup – this stretch is looking more interesting for kite surfing than paddle surfing. Keep the boards in the car and wait for the next proper pulse.
Stay salty,
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.
