The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for this stretch of coast.
To be straight with you, the next 16 days are a tough beat. We’ve got a long gap with nothing worth paddling out for. The first real chance you’ll want to even think about is on Sunday, the 26th of July. Before that, from Friday the 24th right through Saturday, it’s all poor surf with tiny, weak swell and mostly cross-off or onshore wind. Not worth a second look.
That Sunday afternoon, the 26th, things get a little interesting. The swell bumps up to 3 ft from the SE, with a period of 11 seconds – that’s a proper groundswell, and the energy reading is 224 (moderate). The real kicker is the wind: it goes glassy, barely a breath from the West. That’s the cleanest window we’ll see. The break is *Trincomalee*, a point break that’s rarely breaking, so the fact it’s showing anything is a bit of a heads-up. It’s a beginner-friendly spot, but with that little energy and such a rare event, you’ll be scratching for sets. The water temp is about average for the time of year. Still, it’s the only moment where the ocean looks like it might let you have a wave.
After that, we drop right back off. Monday the 27th through to the end of the forecast window on Saturday the 8th of August is a long, flat run. Swell sizes drop to 3 ft, then 2 ft, and eventually down to 1.0 ft or 1 ft. The wind stays stubbornly from the WSW, cross-off, and it’s a fresh breeze (19 mph) for most of it. The energy readings sink into the double digits – weak, tired, and uninspiring. There’s a couple of moments with offshore wind on the 3rd and 5th of August, but the swell is just too small (1.0 ft to 1 ft) and short period to do anything with. It’s a dead zone.
So, the standout? If you’re desperate, that Sunday afternoon on the 26th of July is it. Glassy, clean, and a little bump of groundswell. But don’t expect much. For the rest, the board stays in the car.
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.
