The Lowdown

Alright, Rusty here. Let’s talk about what’s cookin’ for the next couple of weeks.

Honestly, it’s a tough stretch. The forecast is a long, flat spell of poor surf. The only break really on the cards is Trincomalee, a sheltered point that rarely breaks. And for this entire 16-day window, it’s just not doing its thing. The swell is tiny, mostly around 1.0 ft to 2 ft from the southeast, with a short period of 8 seconds – that’s all windswell, no push. The combined energy is weak, barely cracking 34 (34) at the start, and only briefly touching 130 (130) on Wednesday afternoon, but even then the wave comment says “poor surf conditions.” The water’s warm at 84°, which is about average for this time of year, but that’s about the only nice thing I can say.

There’s a bit of a bump in the southeast swell on Thursday the 10th, with a period of 10 seconds and combined energy up to 106 (106), but it’s still only 2 ft. The cross-offshore wind on that afternoon from the NNW at 6 mph makes it glassy and clean, but with that tiny size and the break being inconsistent, it’s a gamble. The best looking session is Friday afternoon the 11th, with a light offshore breeze from the WNW at 9 mph – that’s clean, but the swell is only 1 ft. You’d be on a longboard hoping for a knee-high set.

From the 12th onward, it’s a real struggle. The wind picks up, hitting 25 mph from the WSW through the middle of the second week, and the swell drops to 0.7 ft to 2 ft. The combined energy stays in the teens and twenties – basically flat. The period on the 16th and 17th drops to 4-6 seconds, which is just choppy junk. The whole 16-day window is a write-off for surf. There’s no standout; nothing is even close to rideable. The setup is too small for any paddle surfing, and with the strong cross-offshore winds, it might look more interesting for kite surfing than anything else.

So, that’s the long and short of it. A blank run. It’s a tough one for the area.

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.
