The Lowdown
Right then, let’s have a look at what’s on the table for Trincomalee. I’ll be honest with you, it’s a tough stretch ahead. Over the next sixteen days, there’s nothing that gets the heart racing. We’re looking at a long, flat gap right from the start, with barely a ripple worth paddling for.
The one name on the list is Trincomalee itself, a sheltered point break that rarely breaks. It’s rated for beginners, but honestly, it’s not going to be doing much. The water temp is sitting at 83°, which is about normal for this time of year, so at least the bathwater is warm.
From Tuesday the 11th of August through to Sunday the 24th of August, the swell heights are stuck between 0.3ft and 2ft. That’s not surf, that’s a lake. The combined energy is weak, mostly two-digit values in the teens, 20s, and 30s, with only a few blips around 100 and 135 – barely moderate. The wind is mostly a cross-off from the WSW, which would keep things tidy, but you need waves to clean up.
There are a couple of afternoons, like the 16th and the 21st of August, where the wind goes light offshore from the WNW or W, but with swell at 1.0ft and 0.3ft, it’s a non-event. The period on the 21st is a very long 19 seconds, but with next to no height, it’s just a long-period slosh.
The whole 16-day window is a washout. There are simply no good surf options here. For an area like this, a blank run like this isn’t too unusual. It tends not to stay poor forever, but this stretch is pretty dead.

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.
