The Lowdown
Alright folks, Rusty here with a look at what’s on the cards for Trincomalee. Gotta be straight with ya – this is one of those stretches where the surf gods are on a tea break. There isn't a single decent wave forecast for the entire 16-day window. Not a one.
The ocean’s just not playing ball. We're looking at tiny little swells, mostly from the South-East, that barely tickle the coastline. Sure, the water temp’s sitting around a nice 84° and about average for the time of year, but the wave energy is pitiful, barely reaching double digits for most of the period. The highest energy reading I can see is a weak 94 (on September 25th), and that's a long way off and still attached to poor surf conditions.
Right from Saturday the 12th, it’s a no-go. Onshore winds (ESE at 9 mph) and a weak 2 ft swell from the SE. The wind sticks around, switching from ESE to ENE, keeping everything choppy and bumpy or just plain glassed-off but with zero power. The only time we get a bit of calm is early on Wednesday the 16th, with a glassy morning – but the swell has dropped to a pathetic 1 ft from the SE. You could paddle around on a bodyboard, but you won't be surfing.
From the 17th onwards, the wind swings cross-offshore from the WSW, which is perfect for cleaning things up, but there’s still no swell to work with. The energy is critically low – a lot of it sitting between 12 and 50. The "clean" look is a nice bonus, but it’s clean over a bathtub. Even the "longer period" of 10 seconds on the morning of the 23rd means nothing when the swell height is only 1 ft. The bottom line: Trincomalee is just too sheltered to pick up these tiny, poorly directed southerly pulses.
This kind of blank run is more normal for this sheltered spot, I'm afraid. It's a rare-breaks kind of place, and this is one of those times it's living up to that name. Keep an eye on the charts, though – it tends not to stay this flat forever.

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.
