The Lowdown
Alright, let's talk about the surf ahead. I've looked over the whole 16-day window for this area, and I gotta be straight with you – it's a tough one. Right from the start, there's nothing. The first week is basically a write-off. The swell is tiny, just ankle-snappers at best, and the whole setup is just not doing us any favours. We're talking about a stretch that goes from September 1st all the way through to September 16th with nothing good to recommend. That's a long, flat spell.
Your only real option here is Trincomalee (Sri Lanka). It's a point break, which is a good thing when there's any energy, but this is a spot that rarely breaks. The forecast shows it doesn't get enough swell to turn on at all. The swell directions are all over the place, mostly from the SE, but the optimum direction for this break is from the S. The swell energy is weak across the board, with values like 46 (moderate energy) and 135 (moderate energy) but that's about as spicy as it gets, and even then, the swell height is tiny, never cracking 2 ft. The water temperature is sitting at 83°F, which is about what you'd expect for this time of year, so at least you won't freeze waiting for a wave that never comes.
Most of the time, the wind is cross-off or clean, which would be great if there was any swell to work with. We see a few pockets of glassy conditions on the morning of September 4th and the afternoon of September 3rd, but again – no swell to ride.
This is just one of those periods where the ocean has gone to sleep. There's nothing to get excited about. For kite surfers, this kind of extended flat spell with clean winds is a total bust too.
So, to sum it up: there is no good surf on offer in this 16-day window. It's a rare blank run for this part of the world, but it happens. Sometimes you just have to wait for the next chart to roll in.

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.
