The Lowdown
Alright, Rusty here, looking at the surf situation in Trincomalee.
To be honest, mate, it’s a tough run ahead. We’ve got a real flat spell stretching out through the whole 16-day forecast. The swell energy is weak, barely hitting double digits on the scale – you’re looking at values between 9 and 72, which is basically nothing. We’re talking about waves barely getting to 2 ft at best, and the period is short, mostly hanging around 6 to 8 seconds. That’s windswell, not groundswell, so don’t expect any real power or shape.
Trincomalee is a point break that’s very sheltered and rarely breaks, which makes this kind of run less of a surprise and more of a normal thing for the area. The water temp is sitting around 84°F with an anomaly of 0.9°F, so pretty average for this time of year. Nothing to write home about there.
The wind is mostly cross-offshore, which is a positive, but with no real swell to work with, clean conditions don’t mean much. There is a glimmer on Tuesday the 29th with glassy conditions in the morning, but the swell is still just 1 ft with a period of 8 seconds and the combined energy is only 19. You’d be struggling to get a ride.
Honestly, there are no standout sessions here. If you’re absolutely desperate, the afternoon of Friday the 18th sees the swell height nudging 2 ft from the SE with a period of 8 seconds and energy of 48. It’s still poor surf, but it’s the most energy we’ll see. The wind is light cross-off, so it might be the least ugly wave of the fortnight.
For the rest of the run, it’s just tiny, weak, and poor. You’d be better off doing something else. The forecasts can change, but right now, it’s a solid blank. Don’t hold your breath.
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.
