The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer.
To be blunt, it’s flat. I’m looking at the next 16 days and there’s hardly a ripple worth getting excited about. The whole stretch is a bust, so if you’ve got a board bag full of kites, this might be your window. For paddle surfing, you’re looking at a long, empty run.
The only spot we’ve got to work with is Trincomalee. This is a point break, a real sheltered setup that rarely breaks, and when it does it’s a beginner-friendly wave. Through the entire forecast, the swell barely lifts a whisper, with heights sitting at 0.3 ft to 2 ft. The combined energy is weak, barely hitting three digits, topping out at a modest 117 on Monday, August 10th. That’s the highest spike, but with the sea surface temperature sitting at a warm 83°F, which is pretty normal for this time of year.
The wind is mostly cross-off or offshore, which would be a dream if there was any swell to clean up. We get a light offshore breeze on Sunday morning, August 2nd, from the WNW at 6 mph, but the swell is only 1 ft from the southeast with a period of 9 seconds. It’s clean, but there’s no power. Crowds are possible at Trincomalee when it works, but right now, you’ll have the ocean to yourself.
There’s a slight uptick in period around August 10th, with a 15 to 16-second groundswell hitting that 1 ft mark, but even with that longer period, the energy (105-117) just isn’t enough to make it worth a paddle. For a point break, a long period swell like that can sometimes line up, but we need way more size.
Honestly, for the entire 16 days, there’s not one standout session. It’s a total flat spell. The forecasts can always shift, but right now, this is about as quiet as it gets.
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.
