The Lowdown
G’day, Rusty here. Look, I’ve had a good look at the charts for Trincomalee, and I’ve got to be straight with you – this isn't the week to get excited. The whole 16-day window is a tough one. We’re looking at a total flat spell with nothing rideable on offer.
From Tuesday the 1st through to Wednesday the 16th of September, it’s just one long, frustrating gap. The swell barely crawls above 2 ft, and even then, the period is a short, weak 8 to 10 seconds. The combined energy in the water stays stuck in the weak range, barely reaching 98 for a brief moment on the morning of the 9th, but that’s still tiny at 2 ft. The swell direction is from the SE, which isn’t what the bay likes to see – it’s very sheltered and needs a proper S to get any juice. For a spot that rarely breaks, this is about as bad as it gets.
The water temperature is sitting at a warm 84°, which is about average for this time of year, so at least a paddle would be comfortable, but there’s no wave to push you.
Honestly, the winds are mostly cross-offshore through the mornings, but with that tiny swell, it’s like polishing a pebble. There’s a brief moment on the afternoon of the 11th where it goes glassy, but with the swell dropping to 1 ft and energy at just 36, there’s nothing to ride. This is a stretch where the setup is more for a calm swim than any sort of surf. Usually, when it’s this quiet, it’s normal for the area, but it doesn’t look like changing soon. Keep the board in the bag and hope the forecasts shift.
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.
