The Lowdown
Hey, Rusty again. We’re looking at a major dry spell for Trincomalee (Sri Lanka).
The whole 16-day window is basically flat. The swell never tops 2 feet, and combined energy stays weak. Water temps are about average for this time of year. The wind is a steady cross-off from the WSW, so it’s clean every morning, but there’s just no surf to speak of.
The only glimmer is on Saturday, September 5th in the morning. The swell inches up to a measly 2ft from the SSE, with a slightly longer period at 11 seconds. Combined energy hits 86 – still weak, but the best on offer. You get a light breeze and clean conditions. It’s a tiny, inconsistent bump, and it’s two weeks out, so don’t hold your breath. For a spot that rarely breaks, this kind of stretch is par for the course. Forecasts can change, but right now there’s nothing worth paddling for.
Rusty out.

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.
