The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this stretch is a tough one. We’re looking at *Trincomalee*, a point break that’s “rarely breaks” and is super sheltered. The water’s sitting at a warm 84°, which is about average for this time of year, so no surprises there.
The problem is the swell. The whole 16-day window is a write-off for any decent surf. From now through to the end of the first week, we’ve got tiny, weak waves from the southeast – mostly 1 ft to 2 ft, with periods under 9 seconds. The combined energy barely gets into double digits, mostly in the 20s and 30s. It’s just not doing anything at this break. The wind is cross-off or onshore, and the call is “poor surf conditions” every single day. There’s nothing to get excited about.
Around July 26, we see a little bump – swell height finally touches 3 ft from the southeast, with a period of 11 seconds. The combined energy climbs to 224 and 240 on those two days, which is a moderate poke of energy. But the wind is still cross-off and the break is so sheltered that it’s still being called poor. The swell direction is southeast, and the optimum for this spot is south, so it’s not even coming from the right angle.
The rest of the month and into August is more of the same: tiny, weak, and poor. The only standout in the whole period is a very long-period swell on August 3, with a 16-second period from the SSE. The combined energy is only 44 and 48, though, and the swell height is just 0.7 ft. That’s a groundswell, but it’s so small it won’t get past the shelter. The offshore wind on the afternoon of that day is a nice touch, but there’s nothing to ride.
So, the honest truth: there are no good surf options in this 16-day window for Trincomalee. This is a blank run, and for a break that rarely breaks, that’s pretty normal. Forecasts can change, but right now, you’re better off leaving the boards at home or finding something else to do.
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.
