The Lowdown
Alright, Rusty here again, looking at Trincomalee in feet for you.
Let’s be real: the next two weeks are looking lifeless. We’ve got a big gap of flatness starting Friday the 31st of July. The swell is tiny, maybe 2ft to 3ft from the southeast, but the wind is cross-offshore. The combined energy is a weak 112, and there’s no wave to ride.
From Saturday the 1st all the way through to the 13th of August, it’s just not happening. The swell drops to 1ft to 0.3ft, with periods of 8 to 10 seconds – junk. The combined energy is mostly under 100, often in the teens or single digits. A couple of days show a very long period (20 seconds) on the 7th and 9th, but the swell is only 0.3ft to 0.7ft. No good.
On Tuesday the 11th of August, energy picks up to 115, with a very long 22-second period from the SSE, but the swell is still only 1ft. That long period will just make it wrap and close out on a beach setup. The 12th and 13th of August show similar energy in the 100-140 range, with 1ft swell, but the wind is fresh and cross-off. Still a "poor" call.
The only real bright spot is the mornings of the 13th and 14th of August. On the 13th, we have 1ft of SSE swell with an 11-second period and 25 mph offshore wind – clean. The energy is 93. For a rarely breaking point break that’s very sheltered, this is the best you’ll see. The water is 84°F, which is normal for the season.
The 14th morning is similar – 1ft swell, light offshore wind, and a combined energy of 34. It’s clean, but you’ll be paddling for ankle-biters.
This is a tough stretch. The lack of swell and the fact that this spot rarely breaks means this quiet period is expected. The one standout is the morning of the 13th for a clean, offshore window, but don’t hold your breath for size. Might be better for a kite than a paddle.
This is Rusty, out.

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.
