The Lowdown

Alright surfers, Rusty here. Let’s be straight with you – the outlook for the next couple of weeks is a tough one. We’re looking at a long stretch of small, weak surf with poor conditions. The first real chance of anything worth a mention doesn’t come around for a while, so patience is key.

The whole 16-day window is dominated by tiny, weak swells from the southeast. Wave heights are sitting between 1ft and 3ft, with periods mostly around 8 or 9 seconds – not much grunt behind them. The combined energy is weak, staying under 100 for nearly the entire period, with most values sitting between 16 and 93. That’s a lot of flat days ahead.

Even when the swell bumps up a little, the wind is usually not on our side, often blowing cross-off or onshore, especially in the afternoons. The water temp is sitting around 84°F, about average for this time of year.

Let’s run through the best of a quiet bunch.

Saturday morning, September 5th, we get the biggest swell of the whole window at 2ft from the SE with a period of 8 seconds. The combined energy is a low 50. The wind is glassy from the WSW at 3 mph, which is the cleanest it’s gonna get. It’s surfable for a beginner, but honestly, with that size and short period, it’s not going to offer much shape. Still, it’s the cleanest window.

Wednesday afternoon, September 9th, is another brief flicker. The swell is 2ft from the SE with a 9-second period, and the combined energy finally jumps to 143 – the only time it goes into the moderate range. The wind goes glassy from the NNE at 3 mph. This is the most interesting surf energy we’ll see, but the size is still tiny. For an absolute beginner on a longboard, it might be a laugh, but don’t expect any power.

Beyond that, it’s a desert. From Thursday September 10th right through to Sunday September 20th, the swell drops below 2ft, the combined energy is mostly in the teens and twenties, and the wind stays cross-off. There are a couple of *gentle offshore* moments on the Saturday afternoon of September 12th and Tuesday morning of September 15th, but with only 1ft of swell, it’s barely a ripple.

The only spot we’ve got is Trincomalee, a point break that rarely breaks. Given the tiny swell and very sheltered exposure, it’s simply not going to light up. Most of these days, the setup looks more interesting for a flat-water paddle than a surf.

To be honest, this is a blank run. It’s one of those periods where the surf just isn't on the menu. Forecasts can change, but right now, don’t plan your week around it.

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.
