The Lowdown
Alright, Rusty here. Let’s be straight with you about Trincomalee.
Honestly, looking at the entire 16-day window, it’s a tough stretch. We’re talking about a point break that’s described as "rarely breaks," and the data backs that up. The swell is tiny and the energy is flat. There’s no standout session, no day to circle on the calendar. The water temp is sitting at a warm 84°, which is about average for this time of year, so at least a dip won’t be a shock to the system.
The whole first week is a write-off. From Monday the 7th right through to Sunday the 13th, we see swell heights barely getting over 3 ft, with combined swell energy mostly in the double digits – a weak 42 to a moderate 185. The wind is mostly cross-off from the WSW, which is clean, but there’s just no push. The swell is coming from the SE with a short period of 8-9 seconds. It’s the kind of weak, short-period chop that won’t wrap into a point properly. The surf is labelled "poor surf conditions" across the board. You’d be better off with a stand-up paddleboard or just enjoying a cold drink on the beach.
Moving into the second week, starting Monday the 14th, it gets even smaller. We're looking at swell heights of 0.7 ft to 2 ft for the rest of the forecast. The combined energy drops to pathetic single-digit and low double-digit numbers, like 7, 9, and 10. The period shortens to 8 seconds or less. The wind stays cross-off from the WSW, but it’s often a fresh breeze of 30-35 km/h, which will just blow that tiny bump flat. There is absolutely nothing in this window that qualifies as rideable for a surfer.
So, what’s the best on offer? There isn’t one. This is a blank run. For an area that "rarely breaks," this extended period of no surf is more the norm than a surprise. The forecasts can always change, but as it stands, leave the board at home for the next 16 days.
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.
