The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on offer for the next couple of weeks at Trincomalee.
Straight up, it’s a quiet run. The whole 16-day window is filled with poor surf conditions and there isn’t a single standout day where I’d tell you to drop everything and go. The swell is tiny – we’re looking at 0.3ft to 2ft for the entire period, coming mostly from the SSE or S. That’s barely a ripple. The wind is almost constantly a cross-off from the WSW, which would usually be a good thing for a point break, but with no real energy behind it, it doesn’t matter. The first surf recommendation pops on August 6th, Thursday afternoon, with a tiny 0.3ft swell from the SE at a 9-second period and only 5 (weak energy) in the combined energy reading. It’s just not happening.
Things stay flat and weak all the way through. By Saturday the 10th, we get a bit of a bump to 1ft from the SSE with periods around 10-11 seconds, but the energy is still only moderate at best, topping out around 96 (moderate wave energy) on Tuesday the 11th. Even then, it’s still labelled poor surf. There’s a slight spike in energy on Wednesday afternoon, August 12th, hitting 187 (moderate wave energy) with a 1ft SSE swell at 16 seconds – that’s a longer period groundswell, but the height is just too small to do anything with. You might see a waist-high wave on a good set, but it’d be inconsistent and weak. The water temp is 83°F, which is about average for this time of year.
After that, we slide into another flat spell. From around August 17th into the 21st, the swell drops back to 0.3ft to 2ft, with combined energy values falling into the teens and twenties (weak energy). There’s a brief moment on August 20th where the wind swings around to a light north breeze, but it’s still a cross-off and the swell is a pathetic 0.3ft. The period on that one is 21 seconds, which is very long, but with no height, it’s a total non-event. For the last few days, the wind picks back up to a fresh breeze from the WSW, just keeping the surface clean but doing nothing for the surf.
Honestly, if you’re a kite surfer, you might find this more interesting than a paddle surfer would. There’s consistent cross-off wind, but for wave riding, it’s a blank run. Trincomalee is a point break that rarely breaks anyway, and this forecast confirms it. Don’t hold your breath – forecasts can change, but right now, there’s nothing to chase.
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.
