The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer around Trincomalee. I’ve got to be straight with you – this is a tough one. The swell is tiny, the period is short, and the conditions are just not playing ball. We’re looking at a long stretch of poor surf with no real standouts, so let’s get into it.
We start off on Thursday, 3rd September, and honestly, there’s nothing to get excited about. The swell is a weak 3 ft from the SE with a paltry 4-second period, giving a combined energy of just 21 – that’s weak. The wind is onshore from the ESE at 9 mph, and the conditions are poor. The water temp is a warm 84°F, which is pretty normal for this time of year, so that’s one thing going for us.
The pattern doesn’t change much as we move through the next few days. Friday morning the 4th sees a tiny 2 ft swell from the SE, 8-second period, with a light cross-offshore breeze from the WSW at 6 mph. The water is clean, but the swell is just too small to do anything with. The energy is still weak at 34. This theme continues through Saturday and Sunday – tiny swell, weak energy, and a mix of clean morning conditions and afternoon onshore breezes. The combined energy readings stay well below 100, maxing out at around 80 on the 4th.
As we head into the second week, from Monday the 7th onwards, the winds pick up. We’re seeing consistent 12 to 19 mph cross-offshore breezes from the WSW, which keeps the water clean, but the swell remains pathetic – 1 ft to 2 ft from the SE with periods of 8 to 10 seconds. The combined energy is weak, barely cracking 50 on the 8th, and then drops into the 20s and 30s for the rest of the period. The last few days, from the 14th to the 18th, the wind is a fresh 19 mph breeze, and the energy is bottoming out at 17 on the 16th.
Now, Trincomalee itself is a point break that rarely breaks, and it’s very sheltered. It’s rated as a beginner wave, but with this tiny swell, even that’s a stretch. The optimum swell direction is from the south, and we’re getting SE, so it’s close but not quite right. The crowds are only sometimes a problem, but honestly, there won’t be anyone out because there’s just no surf.
There is absolutely no standout session in this 16-day window. The whole forecast is a solid gap of nothing. For a spot like this, a blank run is more normal when the swell is this weak. Best to leave the boards in the shed and maybe check back in a week or two. Forecasts can change, but right now, it’s a flat spell.
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.
