The Lowdown
Alright, this is Rusty. Let’s get into it, but I’ve got to be honest – the next couple of weeks are looking pretty flat.
Across the whole 16-day window, there’s nothing that really fires up as a good option. The only spot in the picture is Trincomalee. It’s a point break, good shape, and it’s a beginner wave in theory, but it’s a spot that “rarely breaks,” so even when there’s a little energy, it’s a gamble. The water’s sitting at 84°, which is about normal for the season.
We’re looking at a long, quiet run right from the start. From Saturday, July 18th, all the way through to Sunday, August 2nd, every single session is marked as “poor surf conditions.” There are no standouts here. The swell is tiny, mostly under 3ft, coming from the SSE or SE, with a short period between 8 and 10 seconds. Wave energy is weak, only hitting a moderate level like 142 on the afternoon of Sunday the 26th, but it’s still tagged as “poor surf conditions.” The wind is mostly a cross-offshore from the WSW, so the surface looks clean, but there’s just no power in the water.
The swell direction is also off – this break likes it from the S, and we’re getting SE and SSE, so it’s not a great match.
There’s a little bump on Saturday the 25th and Sunday the 26th of July, with the swell hitting about 3ft and the period stretching to 10 seconds, and the energy getting into that moderate range. The wind is a clean cross-off on the 26th morning. But even then, it’s all still “poor surf conditions” because the swell is too small and inconsistent for this rarely-breaking spot.
The only silver lining is a bit of lighter wind late in the run, with a gentle offshore breeze on the afternoon of the 31st of July and the 1st of August, but by then the swell has dropped back to 1ft to 2ft.
Honestly, this is one of those stretches where you’re better off not even loading the boards. There’s just no surf worth chasing. For a spot that rarely breaks, a blank run like this is pretty normal when the swell and direction don’t line up.
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.
