The Lowdown
Alright, grab your board shorts and listen up, it's Rusty here.
Right off the bat, I gotta be straight with you. Looking at the charts for this neck of the woods, there's not a single surfable wave on offer for the entire 16-day outlook. Zero. Zilch. It’s a total flat spell from Monday the 24th of August all the way through to Tuesday the 8th of September. Every single day is tagged with "poor surf conditions" and a score of zero. There’s nothing to get excited about.
The spot here is Trincomalee, a sheltered point break that normally needs a decent push from the south to work. It’s rated as rarely breaking anyway, and that holds true here. The only energy coming in is weak, with combined swell energy values barely cracking 50 (the highest is 54 on the 29th of August afternoon). That’s next to nothing. The swell is tiny, mostly 1 ft to 2 ft from the SSE or SE, with a short, weak period of 8 seconds. That’s not surf, that’s a lake ripple.
For the first week, there’s a persistent WSW wind blowing at 15 to 22 mph, keeping it mostly cross-off shore but way too windy for these pathetic ankle-snappers. The wind does ease a touch on the 29th of August afternoon when it swings lighter and offshore from the WNW, but there’s nothing to ride. Even the rare offshore breezes later on, like on the 31st of August and again on the 8th of September, can’t create a thing worth paddling for.
The water temperature sits at a warm 84°F, which is pretty average for this time of year with a negligible anomaly of only 1°F. That’s the only nice thing I can say. If you want to get wet, do it for a swim, because there is not a single wave for a surfer. A blank run like this is pretty standard for Trincomalee when it’s not in season; it’s a spot that needs the right swell window to open up.
Hang tight, check back with me later. Forecasts can change.

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.
