Table - best surf conditions forecast for Trincomalee over the next 16 days.
G'day, Rusty here. Look, I’ve gotta be straight with you—this outlook for the next two and a half weeks is a tough one. We’re looking at a real flat spell for Trincomalee. The whole 16-day window is a write-off for any decent surf. There just isn't a single period where the conditions come together to offer anything worth paddling out for.
The issue is the swell. We’re stuck with tiny, weak energy running in from the SSE and SE. The combined energy of all swells directed here barely cracks 50 (peak of 57 on the 15th of July), which is weak. Wave heights are sitting at a measly 0.7ft to 2ft for the entire run. That’s barely a ripple. The period is short, mostly 8 to 9 seconds, so there’s no power behind it.
On top of that, the winds are mostly a moderate to fresh cross-off from the WSW at 12 to 22 mph. While it’s clean, it’s just not blowing in the right direction to groom what little swell we have. There’s a tiny window on the afternoon of the 13th of July where we get a gentle offshore from the NW, but with only 1.0ft of swell, it’s still no good.
Trincomalee is a point break that's rarely breaks, and it's very sheltered. This setup confirms it. Honestly, for a spot that needs a decent S swell to light up, this is a blank run. It’s a pretty normal pattern for this area when the swell direction is wrong and the energy is this low. There’s nothing on the horizon here that’s going to change that. Best to save the wax for another week.
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.
