The Lowdown

G’day, Rusty here. I’ve crunched the numbers for Trincomalee over the next sixteen days, and I’ll be straight with you—it’s a flat, quiet stretch. The swell energy is barely tickling the dial, and nearly every report comes back as poor surf conditions. There are no standouts worth a mention. Water temp is a warm 84°F with a 0.9°F anomaly, so about average for the season, nothing noteworthy.

The first sniff of a wave lands on Thursday, September 17th. Trincomalee is a very sheltered point break that rarely breaks, so it takes a miracle to fire. That morning we’ve got a tiny 2ft swell from the SSE with an 8-second period, and the combined energy is a weak 50. Winds are cross-off from the WSW at 15 mph, keeping the surface clean, but the size and juice are really marginal. This spot is beginner-friendly, but with the swell this small and the break so fickle, don’t expect more than knee-high dribble. Crowds are possible here sometimes, but on a day like this you’ll be the only one out.

After that, it’s more of the same. From Friday, September 18th right through to Monday, September 28th, it’s flat and clean with swell heights stuck between 0.7ft and 2ft, mostly from the SE with a short, weak 7- to 9-second period. The combined energy barely breaks 50 and often sits in the teens or twenties. Winds are consistently cross-off from the WSW, mostly at 18 mph, keeping the surface clean but with zero power. There’s a brief moment on Tuesday, September 29th where the wind goes glassy calm from the NW, but the swell is still just 1ft at 8 seconds from the SE, with a pathetic 18 energy. That’s the best of a bad run—a dead flat, glassy morning with nothing to ride.

Bottom line: nothing worth paddling for. The entire 16-day window is a blank run. For this area, that’s pretty normal given how sheltered the spot is. Grab a bodyboard if you must, but for real waves, you’ll have to wait.

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.
