The Lowdown
Alright, let’s get real. Rusty here. Looking at the next couple of weeks for the Trincomalee area, and I'm not gonna lie to you, it’s gonna be a tough watch. We have a solid stretch of flat, weak surf with no real standouts. The board's gonna be gathering dust.
The only spot on the map is Trincomalee (Trincomalee). This is a wave that rarely breaks, and that's certainly the story for this entire forecast period. It's a very sheltered point, which is exactly why we’re in this pickle. The water temp is a comfortable 84°F, which is about normal for this time of year, but that's where the good news ends.
Right now, on the 31st, we’ve got a tiny 0.4m (1ft) southeast swell with a short 8-second period. The energy is a weak 21, and the wind is light and cross-onshore. It’s not doing a thing. We then have a gap of a few days with nothing on offer. There are some clean mornings, like on the 1st and the 5th, with light offshore breezes, but they’re still just 0.4m to 0.5m (1-2ft) of swell. Far too small to get excited about.
The mornings here do stay clean with that WSW cross-offshore wind, which is a big positive for the wave face if there was any size. We see clear skies and gentle to moderate breezes all the way through. Around the 8th and 9th, the swell bumps up to a massive 0.6m (2ft), and the combined energy finally climbs into the moderate range for the first time, reading between 60 and 106. But it's still a 9-second period swell, and there's just not enough push to make this point break come alive.
Into the second week and things fade out fast. We're looking at 0.2m (0.7ft) waves and energy values in the low teens. The 30 km/h (19 mph) WSW cross-offshore winds will keep things looking clean, but there's no ocean movement behind it. It's a long, flat stretch, right through the 14th and 15th. The 15th does try to muster a little more energy with a reading of 62, but with a short 8-second period, it's going to be weak and won't save the week.
I know this looks bleak, but this spot is so sheltered that a dry spell like this is pretty normal. If you're still keen, you'd need a longboard and a whole lot of patience, but honestly, paddle surfing is not the move. With that much wind and that little wave, it's looking like a better setup for kiting than surfing. For now? There’s nothing here.
Hang in there. Forecasts can change, and while the consistency isn't great, it doesn't usually stay this poor for long. I'll be watching.
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.
