The Lowdown
G’day, Rusty here, and I’ve gotta be straight with you – the next 16 days up at Trincomalee are looking pretty flat. This is a real quiet spell for this spot, and it’s gonna be a long wait for anything that even gets you out of bed.
The first week is a total write-off. From Thursday, 16 July, right through to the end of the month, we’re looking at tiny swell. The waves are barely breaking at 1 ft to 2 ft, coming mostly from the SE or SSE, with a short, weak period around 8–11 seconds. The combined swell energy is low, sitting between 13 and 137 (weak energy), and the wave comment is “poor surf conditions” for every single session. The wind is mostly a cross-off from the WSW, which is okay for keeping the surface clean, but there’s just no power in the water. The water temperature is about average for the time of year.
Now, the break itself is a point, and it’s rarely breaks, so this kind of blank run is more normal for the area. It’s also very sheltered from the swell, so it needs a solid push from the south to really work. The optimum swell direction is from the south, but the swell is coming from the SE and SSE, so it’s not even lining up right.
The best of a bad bunch happens around Sunday, 26 July, and Monday, 27 July. The swell nudges up to 3 ft to 3 ft from the SE, with a period of 10 seconds, and the combined energy climbs into the moderate range (126–137). The wind stays cross-off from the WSW, keeping the surface clean. It’s still not great, but it’s the biggest we’ll see. For a beginner-friendly point that rarely breaks, this is the only window where you might catch a few small, clean lines. Expect crowds to be possible, especially if word gets out that there’s any ripple at all.
The outlook for the first week of August doesn’t look much better, with the swell dropping back to 2 ft–2 ft and weak energy. The wind is still cross-off, but the lack of swell means it’s still a no-go. Honestly, mate, unless you’re desperate for a paddle and a longboard cruise, I’d give this one a miss. The forecasts might change, but for now, it’s a quiet one.
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.
