The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook for the Trincomalee area is a tough one. We’ve got a 16-day window staring at us, and honestly, there’s nothing to get excited about. The first recommendation doesn’t come until Saturday the 22nd of August, and even then, it’s a flat, windy mess. We’re looking at a long, dry spell with no real surf on offer.
The main issue is the swell. We’re stuck with tiny waves, barely 1 ft to 2 ft, coming out of the southeast. The combined energy is weak, sitting at values like 27 or 34 (weak energy), which just isn’t enough to push any kind of rideable wave. The periods are short, around 8 to 10 seconds, so it’s all windswell. To make matters worse, the wind is a cross-off from the WSW, blowing at 15 to 22 mph nearly every day.
Now, the only break on the list is Trincomalee, a sheltered point break that’s rated for beginners. But it “rarely breaks” and is “very sheltered” from the swell. The water temperature is a warm 84°F, which is about average for this time of year, so at least it’s a nice swim. The optimum swell direction for this spot is from the south, and we’re getting southeast and south-southeast, so it’s not even arriving right.
The entire period is a write-off. From Saturday the 22nd right through to Sunday the 6th of September, every single time slot is marked as “poor surf conditions.” The wind is relentless, the swell is non-existent, and the energy is too weak to do anything. The only small change is on Saturday the 29th of August, when the afternoon wind switches to a gentle offshore from the west at 9 mph, giving a “gentle offshore and clean” look. But even then, the swell is only 2 ft with a combined energy of 59 (still weak energy). It’s a tease, not a session.
If you’ve got a kite, this constant cross-off breeze might be fun, but for a paddle surfer, there’s simply nothing here. The waves are too small, the wind is too strong, and the consistency is zero. Sometimes the forecast can change, but for now, save your energy and don’t bother paddling out.
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.
