The Lowdown
Alright, folks, Rusty here. Let’s get real about the next couple of weeks. Honestly, this is a tough one to call. The entire 16-day window is looking flat and disappointing, with no real surf to speak of. We’re looking at a long stretch of poor conditions, so if you’re dreaming of waves, you might want to plan a trip elsewhere.
The first sign of anything is from Saturday, the 15th of August, right through to the end of the month, and it’s all the same story: tiny, weak swell. The primary spot, Trincomalee, which is a sheltered point break, is seeing barely a ripple. The swell energy is weak, ranging from (85) down to as low as (8) – that’s barely enough to move a sea kayak. The swell direction is coming from the SE, which is not the ideal south swell direction for this spot. The height is a measly 0.7 ft to 2 ft, with periods that are all over the place, from a short 8 seconds to a long 19 seconds, but it doesn’t matter when the energy is that low.
The winds are mostly cross-off or cross, with a few moments of glassy or light offshore conditions, like on the afternoon of Thursday the 20th of August, or the afternoon of Saturday the 29th of August. But even with clean, glassy water, there’s just no swell to ride. It’s a cruel tease. The water temperature is about average for this time of year, so no surprises there.
Honestly, for the whole 16 days, the scores are all zero. This break is “rarely breaks” anyway, and this forecast is a perfect example of why. There’s a brief moment on the afternoon of Saturday the 22nd of August where the energy jumps to (115) with a 1 ft swell from the S at 18 seconds, but it’s still poor surf. That long period (18 sec) is a groundswell, but with such a tiny height, it’s just not going to produce anything rideable. Even for a beginner, there’s nothing to catch.
If you’re a kite surfer, the consistent cross-off winds might be interesting, but for a paddle surfer, this is a blank run. Don’t hold your breath; forecasts can change, but it’s a flat spell for the books.

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.
