The Lowdown
Alright, this is Rusty, and I'm looking at the charts for the Trincomalee area. To be honest, mate, it’s a tough stretch ahead. The whole 16-day window looks flat as a pancake. We’re looking at tiny, weak swell from the southeast, mostly under 2 feet. The wave energy is pathetic, barely a whisper. It's just not going to do anything.
The one spot on the cards is Trincomalee itself. It's a point break, which is a positive, but it's sheltered and rarely breaks. For this kind of setup to fire, you need a solid swell from the south, and we’re just not getting it. The wind isn't the problem for most of the period, often cross-off or even glassy on the afternoon of the 28th, but with no real swell, that doesn’t matter. The water temp is sitting around 83° on that first morning, which is about average for this time of year.
Honestly, there isn't a standout day. There's no surf to recommend. It’s a blank run that will last the entire 16 days. When a spot is this inconsistent and the swell is this weak, you're better off leaving the boards at home. Forecasts can change, but as it stands, this is a dead period.
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.
