The Lowdown
Alright folks, Rusty here. Let’s be straight with you—this 16-day window for Trincomalee is a tough one. The first few days are basically a write-off with tiny, weak swell, so we’re looking at a gap of about a week before any real energy shows up. Don’t get your hopes up too early.
The first sign of anything worth paddling out for doesn’t really arrive until Wednesday the 22nd of July. Through the afternoon, we get a glassy moment at Trincomalee (point break). The swell is small, only 1 ft from the SE with a short period of 8 seconds, and the combined energy is weak (25). But with the wind going glassy (NE at 3 mph), the surface will be clean. It’s a tiny window and the spot is rarely breaking, so it’s a gamble, but if you’re desperate for a glide, that’s the moment.
The real standout, if you can call it that, comes on Saturday the 25th of July. During the afternoon, the swell pushes up to 2 ft from the SSE with a period of 10 seconds, and the combined energy hits 95—still weak, but the best we’ll see. The wind is light from the north at 9 mph, cross-off, so the waves will be clean. For a point break that’s rarely breaking, this is the pick of the entire outlook. It’s tiny, but it’s the best on offer.
After that, we roll into the last few days of the month. The swell stays around 2 ft from the SE, periods between 8 and 10 seconds, and energy climbing into the low triple digits (115 on the 28th). The wind is a cross-off from the WSW at 15 mph, so it’s clean but not glassy. For a beginner-friendly point, it’s rideable but nothing to write home about. The water temperature is about 83°, which is normal for the time of year, so no surprises there.
Overall, it’s a flat run with a couple of tiny, clean windows. If you’re a beginner or just want to get wet, the 25th afternoon is your best shot. Otherwise, keep your board in the car and stay ready—forecasts change.

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.
