The Lowdown
Alright folks, Rusty here, and I gotta be straight with you – this outlook is a tough one. We’re looking at the next 16 days for the Trincomalee area, and honestly, there’s just nothing happening on the surf front. The whole period is a flat spell. We’re talking about waves that barely reach 2 ft at best, with a weak, short-period swell from the southeast that just doesn’t have any push. The combined swell energy never gets out of the double digits, sitting between 16 and 81 (weak energy), so there’s no real power in the water.
Starting from Thursday, September 3rd, right through to Friday, September 18th, it’s the same story day after day. The swell is too small and the period is too short to make anything worthwhile. The wind is mostly cross-off or glassy, which would be a dream if there was any swell, but with these tiny waves, it’s just a cruel tease. The water temperature is about average for this time of year, so no surprises there.
The only break we have to talk about is Trincomalee, a point break that rarely breaks. It’s very sheltered, and with the swell coming from the southeast instead of the optimum south, it’s just not firing. This is a spot that needs a proper south swell, not this weak, short-period junk. Even the glassy, offshore conditions on Thursday afternoon won’t save it.
Bottom line: if you’re looking to paddle surf, you’re out of luck. This is a blank run, and it’s pretty normal for this area when the swell direction is off. The wind is strong enough that it might be more interesting for the kite surfers out there, but for the rest of us, it’s a waiting game. Forecasts can change, so don’t lose hope, but for now, the board stays in the shed.
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.
