The Lowdown
Alright, grab a seat. Let’s talk about what’s on offer for the next couple of weeks.
First off, I gotta be straight with you – we’re looking at a pretty grim picture for the next 16 days. There’s a real lack of swell energy and the conditions are just not playing ball. The finder is showing nothing but "poor surf conditions" across the entire period, so we’re in for a long, flat run.
The first days are a bust. From Saturday, 1st August right through to the end of the first week, we’re talking tiny, gutless swell. We’re looking at waves of 2 ft or less, mostly from the SE but with a period that’s all over the place – from a weak 8 seconds up to a single 14-second pulse on the 5th. The wind is a persistent problem, too. It’s a fresh breeze from the WSW or SW, blowing cross-offshore, which at least keeps the surface clean, but with combined swell energy readings mostly in the single digits or low double digits, there’s just no power to work with. The water temp is a warm 83° – about average for this time of year – but that’s no comfort when there’s nothing to ride.
Now, there’s a brief flicker of life around the second week. On Saturday, 8th August, the afternoon shows a combined energy of 120 (moderate) with a 1.6 ft swell from the S. That’s still tiny, but it’s a bit more movement. Then on Sunday, 9th August afternoon, we get a 1.3 ft swell from the S with a very long period of 19 seconds, pushing the energy up to 148. That’s the most interesting pulse of the whole period, but it’s still a very small wave. A long period swell like that will be super clean at Trincos, but it’s only a whisper. The wind is still a fresh cross-off, so it’ll be glassy, but the wave height is just too small for any real fun.
The rest of the second week is more of the same. There’s a bit of a bump on Thursday, 13th August morning with a 1.3 ft SSE swell and a 14-second period, giving an energy of 130, but it’s still a very marginal wave. The wind keeps blowing fresh from the WSW. By Friday, 14th August, the wind finally drops to a light breeze, and we get a 2 ft SE swell with an 11-second period, but the energy is only 88. It’s the best we’ve seen, but it’s not enough to get excited about.
Given the whole 16-day window is a write-off, I wouldn’t be making any plans. The break is a rare, sheltered point, and it just doesn’t have the swell to work. For a spot that’s rarely breaking, it’s not surprising we’re looking at a blank run. It’s a real shame. Keep an eye on the charts, though – it tends not to stay this poor for long.

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.
