The Lowdown

G’day, Rusty here. Let’s be straight with you: the next 16 days are a tough beat for surf around Trincomalee. We’re looking at a long, flat stretch with barely a ripple worth paddling for, so don’t get your hopes up.

Right from the start, Tuesday 25 August through the end of the week, it’s all tiny windswell – nothing above 2ft, and even that’s pushing it. Swell energy is weak, mostly in the teens and twenties (14 to 43 on the energy scale), which is barely enough to tickle a longboard. The wind’s blowing cross-off from the WSW at 15 to 22 mph, which keeps the surface clean, but with such small, short-period swell from the SSE at only 8 seconds, there’s just no push. The break is a very sheltered point that rarely breaks, and honestly, it’s not breaking now. The water sits at 84°F – about normal for the time of year, so nothin’ to write home about.

That flat spell hangs around through the first week of September. Thursday 4 September offers a flicker of hope with a light breeze down to 6-9 mph, but the swell’s still stuck at 2ft and 9 seconds, energy still low (42). Still poor conditions. By Monday 7 September afternoon, the wind goes glassy from the ENE at just 3 mph – that’s a rare clean window – but the swell’s only 2ft at 10 seconds. It’s glassy, but there’s no real wave to ride.

The best of a bad bunch? You’d have to point to Monday 7 September afternoon – and even then, it’s a stretch. The point break stays clean with that glassy wind, and the period stretches to 10 seconds, giving the tiny 2ft SSE swell a bit of shape. Energy nudges up to 73, which is still weak but better than the rest. It’s a rare break, and crowds are sometimes a factor here, but with conditions this poor, you might have the place to yourself. Still, this is only for the committed beginner or someone who just wants to sit on a board and feel the ocean.

For the rest of the outlook, it’s more of the same: small, weak, and poor. The energy never cracks 106, and that’s only one session (Tuesday 1 September afternoon) with a 3ft SSE swell at 7 seconds – that’s short-period junk, not worth the drive. The last few days, 7 to 9 September, stay around 2ft to 2ft, with a mix of cross-off winds and one more glassy moment, but it’s all still poor.

Bottom line: there are no good surf options in this 16-day window. Trincomalee is a sheltered spot that needs a proper southerly groundswell, and we just don’t have it. The guidance shows the break as rarely breaking and very sheltered, so a blank run like this is more normal for the area. Forecasts can change, but for now, leave the board at home.

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.
