The Lowdown
Alright, Rusty here. Let’s look at what’s on offer for Trincomalee.
To be straight with you, the next 16 days are a tough watch. The forecast keeps showing tiny, weak swell, and the setup is very sheltered. The reality is there are no good surf options in this entire window. The waves just aren’t there. The first few days barely register a bump, with swell hanging around 0.3 ft to 0.7 ft from the SSE, and the energy is way down – we’re talking single digits and very low double digits for combined energy, like 5 to 55. That’s not surf, that’s a ripple. The water temperature is sitting at 83°F, which is pretty normal for this time of year, so no surprises there.
The persistent cross-off wind from the WSW doesn't help either. It keeps the surface clean, but with no height to work with, clean doesn't mean a thing. There’s a long stretch of nothing, especially from the 4th through to the 10th, with the swell barely touching 1 ft. It’s a blank run, and for this area, that’s not unusual. The break itself, Trincomalee, is a point that rarely breaks, and this forecast spells that out perfectly.
Looking a bit further out, the 11th of August (Tuesday) afternoon brings a tiny tick up with a 1.0 ft swell from the SSE, but the period shoots up to 20 seconds, giving a combined energy of 122 (moderate energy). The wind finally turns offshore from the WNW, which is a good sign. Still, it’s a long-period groundswell that’s barely breaking. That’s a tease, not a session.
The 17th of August (Monday) afternoon offers a glimmer with glassy conditions and a 2 ft SSE swell, but again, the energy is modest at 78. It’s clean, but the size is just not enough to get excited about. For the rest of the run, we’re stuck with 1 ft to 2 ft swell and moderate to fresh breezes.
Bottom line: if you’re looking at this stretch, don’t bother. The setup is more interesting for a kite surfer than a paddle surfer, given the consistent wind and lack of wave power. Take a break, check back another time. Forecasts can change, but this run looks cooked.
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.
