The Lowdown
Alright, grab a seat. Rusty here. Let's talk about what's on the table for the next couple of weeks. I'll be straight with you – it's a quiet stretch, so keep your expectations in check.
We're looking at a long run of small, weak surf. Right from the start through the entire 16-day window, the wave heights barely tickle the 2-foot mark. The energy is mostly low, with combined swell energy values often sitting below 100 (like 53 or 83), and even the slightly livelier spells only flicker into the low 100s (like 119 or 149). Periods are a mixed bag, with some pulses of long-period groundswell in the 11 to 20-second range, but with the swell coming from the southeast or south, those longer lines won't have much push behind them.
Let's talk about the only spot on the radar: Trincomalee (Trincomalee). It's a point break, a beginner-friendly setup, but it’s rated as "rarely breaks," so you really need the stars to align. The water temp is sitting at 84° with a positive anomaly of 1°, so it's pretty much what you'd expect for this time of year. The wind is mostly a cross-off from the WSW, which keeps things clean, and there's even a glassy moment on the morning of Wednesday, August 19th with a light offshore from the NW. That is about as good as it gets, but the wave is tiny—2 feet from the SE. The crowds are described as "sometimes," so you might have a few others hoping for the same bump.
There's a brief peek on Tuesday, August 11th, afternoon. Swell from the SSE at 1.0 feet but with a very long period of 20 seconds and combined energy hitting 149 (moderate). That's a proper groundswell, but at that height, it's just a push of water with no real face to surf. Still, the point break is where you want to be for those long-period lines so they don't just roll through.
On Wednesday, August 12th, afternoon, we see 2 feet from the SSE with an 11-second period, and energy at 118 (moderate). That might be the most rideable window, with clean conditions. Then again on Friday, August 14th, morning, another 2 feet SSE swell, same period, clean, with energy at 119. These are the real standouts, but calling 2 feet a standout tells you everything about the overall outlook.
Honestly, if you're looking for a proper session, this is a quiet period. The runs of poor conditions are near-continuous. The tiny size and sheltered nature of Trincomalee mean it might be more interesting for a float than a surf. Keep an eye on the glassy morning of the 19th, but 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.
