The Lowdown
Alright, let’s break this down. First up, Trincomalee – a point break that’s a sheltered little number. The water’s warm, around 84°F, which is about average for this time of year. But here’s the rub: this spot rarely breaks, and looking at the whole 16-day run, it’s all "poor surf conditions" with no real standouts. The swell is tiny – think 0.7ft to 3ft from the southeast, with periods mostly between 8 and 10 seconds, so nothing with any grunt. The combined swell energy is weak, mostly under 100, with the biggest bump hitting 181 on the afternoon of September 9th, but that’s still weak to moderate.
Wind-wise, there are a few bright spots. On the morning of September 7th, Monday, it’s glassy with a light 3 mph breeze from the southwest. That’s as clean as it gets. Then on September 9th, Wednesday afternoon, you get a light offshore from the west at 6 mph, which would smooth things out. But even then, the wave height is barely 3ft and the period is a short 9 seconds – not exactly firing. For the rest of the run, it’s mostly cross-offshore winds, with some moderate to fresh breezes, especially from September 14th onward, with gusts up to 25 mph. That’s not helping.
With no real swell and a spot that rarely breaks, there’s nothing for a surfer here. On the windier days, this setup looks more interesting for kite surfing than paddle surfing. It’s a quiet stretch – forecasts can change, but right now, it’s a long blank run. Hang tight.

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.
