The Lowdown
G'day, Rusty here. Let's be straight with you—this outlook for Trincomalee is a tough one. We're looking at a long, dry spell with no real surf to speak of across the entire 16-day window. The finder's come up empty, and honestly, looking at the guidance, it's not surprising. This spot is a point break that's very sheltered and rarely breaks, so a blank run like this is more normal than unusual for the area. Don't hold your breath, but forecasts can change.
Right now, from Thursday the 30th of July, and well into the first week of August, it's all tiny, weak swell. We're talking a combined energy around 101 on Thursday morning, dropping into the double digits by the weekend. Swell heights are stuck between 1 ft and 2 ft, all coming from the SE with a period of 8 to 10 seconds. Not a lot of push there. Add in a solid 19 to 25 mph WSW wind—cross-off, sure, but it's a strong breeze—and you've got clean conditions but nothing to ride. The water temp is sitting around average for this time of year.
Come the weekend of the 1st and 2nd of August, the wind backs off a touch to a gentle breeze, even going offshore from the NW on Saturday afternoon. The swell drops further, though. 1 ft to 2 ft max, with energy sinking to 64 then 29. Still poor. By Monday the 3rd, we're down to 1 ft and 17 of energy. It's a dusty period.
There's a slight uptick mid-week, with 2 ft to 2 ft swell and energy climbing back to 95 by Wednesday the 12th of August. Swell period gets up to 11 seconds, which isn't bad, and the wind is a constant cross-off from the WSW at 19 to 22 mph. Clean, but the swell size just isn't there for a decent wave. The highest energy spike we see hits 143 on Friday the 14th of August from a 2 ft SSE swell, but with a strong breeze, it's all show and no go.
So what have we got? Trincomalee is an inconsistent, sheltered point that needs a very specific window. This 16-day stretch just isn't it. The setup is more interesting for a kite surfer than a paddle surfer given the persistent, clean cross-off wind, but for the rest of us, it's time to wait for a better forecast.
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.
