Alright, let’s break it down, mate. I’ve had a look at the charts for the next 16 days, and I’ll be honest – it’s a tough one. The only break on the menu is Trincos, and it’s looking like a real snoozer.
We’re in for a long, quiet stretch. From Saturday, 4 July, right through the first week and a half, the swell is just pathetic. The forecast is calling it poor surf every single day. There’s no standout session, no day to get your hopes up. It’s a solid run of flat to gutless conditions.
Trincomalee is a point break that rarely breaks, and this forecast proves it. The wind is mostly a cross-off from the WSW, which is fine, but the swell is simply not there. For the first week and a half, we’re stuck with a weak 1ft to 2ft swell from the SE, with periods around 8 to 11 seconds. The combined energy is weak, sitting between 19 and 35 (34 on the 4th, 25 on the 5th, and so on). That’s barely a bump. The water is a warm 85°F with the anomaly about 2°F above normal, so it’s nice for a dip, but not for a surf.
There is a tiny flicker of life around Wednesday, 15 July. The afternoon shows a bump to 3ft from the SE, period 8 seconds, and the energy jumps to 103 (moderate) – the first real number we’ve seen. But it’s still being called poor surf conditions with a fresh breeze. The swell direction is from the SE, and the optimum is S, so it’s not even lining up right.
The last few days, from 17 to 19 July, the swell does creep up to 2ft and 2ft, and the energy reaches 79 and 67, but the period stays short (8-10 seconds) and the wind remains cross-off. It’s still a no-go.
Honestly, for a spot that’s as sheltered and inconsistent as Trincos, this kind of blank run is normal. It’s not the time to get excited. Unless you’re desperate for a float in warm water, give this one a miss. The forecasts can change, but right now, there’s nothing to chase.

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.
