The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Trincomalee.
To be straight with you, the next 16 days are a tough watch. The swell is tiny, pretty much nothing over 2ft, and it’s coming from the southeast, which isn’t ideal for this spot. The water is a warm 84°—about normal for this time of year. But the energy is weak, with combined energy readings barely cracking 40 (32) most of the time, and only a couple of days where it nudges into the low three-digit range. Honestly, for a point break that rarely breaks, this is a long stretch of flat or near-flat conditions.
The best of a very quiet bunch falls on Wednesday the 9th and Thursday the 10th. On Wednesday the 9th, a modest pulse of energy (132) bumps the swell to 2ft from the southeast at 9 seconds. The wind is a steady cross-off from the WSW at 18 mph, keeping the surface clean. It’s still small, but it’s the most energy we’ll see. Thursday the 10th holds similar size in the morning, with a bit less energy (68) but still clean. On Thursday afternoon, the wind shifts to a light offshore from the WNW at 6 mph, which is a nice touch for such a sheltered spot.
Other than that, there are long gaps of nothing to write home about. The conditions are either clean but tiny, or blown out by onshore breezes. The swell is just too weak and short-period to make anything of this point break. For a spot like Trincomalee that’s rarely breaking, we’re in a real dry spell. It’s not a total shock for the area, but it’s certainly not what we’re after.
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.
