The Lowdown

G’day, Rusty here, and I gotta be straight with ya – the next 16 days around Trincomalee are about as flat as a lake on a still morning. We’re looking at a long, quiet stretch with barely a ripple to get excited about.

The first real recommendation doesn’t even pop up until Thursday the 20th of August, and even then it’s a tough ask. The swell is tiny, just 0.7 ft from the south with a period of 16 seconds – that’s a long-period groundswell, but with barely any energy behind it (combined energy of all swells directed here is only 31). The water’s sitting at 84°, which is about average for this time of year, so no surprises there. But the wind is howling at 19 mph from the WSW, cross-off, making it messy and ugly. The spot itself is a point break called Trincomalee, and it’s marked as “rarely breaks” – and for good reason, because there’s nothing to ride. Crowds are “sometimes” a problem, but honestly, who’s gonna be out there?

Friday the 21st and Saturday the 22nd are more of the same – tiny swell, 1 ft at best, with short periods of 7-8 seconds. The wind stays up, 16 to 19 mph, and the energy is weak (34 on Saturday morning). Saturday afternoon does see a slight bump to 3 ft and 131 energy, but it’s still a no-go with poor conditions flagged. Sunday the 23rd through to the end of the month just drags on – 1.0 ft to 2 ft, periods mostly around 8 seconds, and wind that never lets up. There’s one moment on Monday the 24th of August where the wind drops to 3 mph from the NNW and it goes glassy, but the swell is a pathetic 1 ft. You’d be sitting on a board doing nothing.

Moving into the second week, it’s the same story. Tuesday the 25th to Thursday the 27th – all 1 ft to 2 ft, 8-second periods, and cross-off winds. Friday the 28th and Saturday the 29th offer a tiny glimmer: Saturday afternoon sees a lighter 6 mph from the WNW that’s offshore, but the swell is still only 2 ft from the SE. Sunday the 30th and Monday the 31st are no better, with energy struggling to hit 62. Tuesday the 1st of September through to Friday the 4th of September is a dead end – 1.0 ft to 3 ft on the last day, but still with a combined energy of 123 and a 7-second period, all flagged as poor. The wind is a constant 12 to 16 mph cross-off.

So, the honest truth? There’s no standout here. Nothing worth paddling out for. The whole 16-day window is a write-off. Trincomalee is a very sheltered, rarely-breaking point break, and this kind of flat run is just normal for the area. Forecasts can change, but right now, it’s a solid “leave the boards at home” situation.

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.
