The Lowdown
Alright folks, Rusty here. Let’s be straight with you: the outlook for Trincomalee over the next 16 days is a tough one. We’re looking at a real flat spell, with no good surf on offer from the start. The first recommendation doesn’t kick in, because there simply isn’t any worthwhile ride. The whole period is a near-blank run, with nothing but tiny, weak swells and mostly poor surf conditions flagged every day.
From Friday, August 14 right through to Saturday, August 29, the swell is tiny – mostly between 0.7ft and 3ft – and the combined energy is weak, sitting between 18 and 97 (97 is the highest, still weak). The wind is cross-off or cross-on most of the time, but it doesn’t matter because the surf is just too small. The water temperature is about 84°, which is pretty normal for the time of year, so no surprises there.
Trincomalee is a point break that’s rarely breaks and is very sheltered. It’s a beginner-friendly spot, but even with the optimum swell direction coming from the south, the swell is from the SSE and SE, and the heights are pitiful. There’s nothing here to get excited about. The only slight blip is on Saturday, August 22, afternoon, when the swell bumps up to 3ft from the SSE, but the period is a short 7 seconds and the energy is still weak at 97. It’s still poor surf conditions.
Honestly, for a spot that’s rarely consistent, this kind of blank run is more normal for the area. Forecasts can change, but right now, there’s no reason to paddle out. Save your energy.
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.
