The Lowdown
G’day, Rusty here, your local surf reporter.
Alright, let’s be straight with it – the forecast period from now through the next 16 days is a tough one for waves around here. The only spot that ever gets a mention is Trincomalee, a sheltered point break that’s rated for beginners but rarely breaks. And it’s not looking good at all. There’s a real gap in any decent surf from the start right through to the end of the outlook. You’re looking at day after day of flat, tiny swell with poor surf conditions flagged all the way.
The water temperature at Trincomalee is sitting at 84°, which is 1° warmer than average for this time of year – nothing unusual there, just your typical warm tropical bath.
From Friday 7 August afternoon through to Saturday 22 August afternoon, the swell heights barely scrape 2ft, and mostly sit around 0.3ft to 1ft. The swell direction is a mix of S, SSE, SE – not ideal for this very sheltered setup that prefers S swell. The swell period is short, most of it under 12 seconds, with some real weak 8 and 9 second stuff. The combined wave energy is pathetic – the highest reading is 167 (moderate energy) on Tuesday 11 August afternoon, but even then the swell is only 2ft from the SSE. Most days the energy is below 100 (weak), meaning the ocean is basically flat soup.
Winds are cross-offshore from the WSW at 12–19 mph for most of the outlook, which is clean but not helping the tiny waves. A couple of afternoons on Saturday 15 and Sunday 16 August see light offshore WNW winds at 6 mph, which would be glassy – but again, there’s no swell to shape.
The standout? There really isn’t one. The best you could hope for is maybe a knee-high dribble on Tuesday 11 August afternoon with 2ft SSE swell and 12-second period, but even that’s a stretch. The wave comment says “poor surf conditions” for every single record. This is a blank run, and it’s not unusual for this area when the swell window is closed.
If you’re a kitesurfer, the strong cross-off winds and clean water might be more your thing – but for paddle surfing, it’s a total write-off. The forecast confidence is high for the near term, and the long-range doesn’t offer any hope either.
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.
