The Lowdown
Alright, grab a seat because honestly, there’s not a whole lot to get excited about. Over the next 16 days, Trincomalee is basically in a flat spell. The combined wave energy never really kicks off—the best it gets is a weak 48 (moderate energy) on Monday the 24th, and that’s just a pulse in a sea of tiny numbers. We’re seeing ankle-to-knee high waves from the SE or SSE most days, with periods all over the place, from short 8-second wind slop up to a slow 18-second groundswell on the 24th. But with sizes barely hitting 1.6 ft., that long period just means long waits for nothing.
The water is sitting around 83°F for the first break I’m talking about—that’s about normal for this time of year, so no worries there. But the problem is the wind. Most days we’ve got a moderate to fresh breeze hammering in from the WSW—cross-offshore at Trincomalee, which is actually clean, but the swell just isn't there to ride. A few afternoons see a light cross-on from the NE or ENE, but again, the surf is poor.
The only break on offer is Trincomalee—a rare-breaking point break suited for beginners. It is "rarely breaks," and this forecast is proof. The optimum swell direction here is from the south (S), but the swell we are seeing is mostly from the SE or SSE. It doesn't match up. Even the bigger pulse on the 24th at 0.7 ft. from the S with an 18-second period is basically flat.
There are gaps of days with no recommendations because, frankly, every single session is scored as poor surf conditions. The whole 16-day run is a blank. For this area, a run like this is pretty normal—it tends not to stay poor for long, and forecasts can change, but right now we're in the waiting room.
Stick to the sand for now. If you absolutely have to get wet, the cleanest-looking windows might be on Wednesday the 19th morning with a light cross-off breeze, or the 29th when glassy conditions pop up, but you’ll be paddling for nothing. This setup looks way more interesting for kite surfing than paddle surfing if the wind holds.
Stay patient.

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.
