Alright, Rusty here again. Let’s break down the same outlook for the imperial folks.
Honestly, it’s a tough one. For the first week, from Saturday the 11th through to Friday the 24th of July, you can hang the board up. The swell is tiny – we’re talking 0.7 ft to 1 ft. The energy is weak (every reading is under 100), and even with some long-period groundswell, there’s just no power. The wind is a moderate cross-off, but it’s a non-factor when the waves are that small. Trincomalee is a sheltered point that rarely breaks, and unfortunately, this forecast backs that up.
The only day that even hints at life is Saturday the 26th of July. The morning shows a 2 ft southeast swell, with a 10-second period. The combined energy finally hits 103, which is still weak, but it’s the best of the bunch. The wind will be a moderate cross-off from the west, so the surface will be clean. But even then, the forecast calls it poor surf conditions. For a spot this sheltered, you need a lot more push.
There’s no standout. The water is about 84°F, which is normal for this time of year, so it’s a nice swim. But for surfing? This is a kiteboarding window if you’re keen, but not for a paddle surfer. A blank run like this is typical for a super-sheltered break like Trincomalee, but forecasts can change, so don’t lose hope entirely.
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.
