The Lowdown

Right, listen up. It’s Rusty here, and I’ve got to be straight with you: the surf outlook for our little slice of the coast isn't exactly firing. We’re looking at a solid run of small, weak surf, and for the next week or more, there’s nothing that’s going to have you scrambling for your board.

The main issue is that we're starved for size, and the energy in the water is just gutless. For the first few days, we’re looking at waves around 2ft, maybe dropping to 1.3ft, with periods mostly in that 8 to 10 second range. The energy readings are weak, too, mostly in the two-digit numbers like 95 or 101 for Thursday, but falling off a cliff to 40 and below by the weekend. It’s just a lot of push and pull with no real power behind it. The wind is mostly cross-off or cross, which keeps things clean, but you can’t surf clean mush.

There are no standout days here. It's a blank run of poor surf conditions, to be honest. The one spot we have is Trincomalee, a point break. It’s a rare-breaker, so to see it with any waves is a treat, but the swell is just too small. Even with the swell coming from the SSE and SE, which is the right direction, the wave heights are barely ankle-snappers. There was a glimmer on the Friday afternoon when the wind went glassy and the period bumped to 9 seconds, but with a weak energy reading of 74, it just wasn't enough. It’s one of those days where you'd paddle out for the peace of it, not for the rides.

The water temperature is about average for this time of year, so you won't need the thickest suit, just a decent one. The local winds are mostly WSW and SW for the next two weeks, which is generally cross-off, but on the 15th, we see the wind shift to the W and get up to 19 mph, giving us a fresh offshore breeze. That'll clean things up, but there’s still zero swell behind it.

The long-range calls, for the second week, are still looking pretty poor. We’ve got the same small, weak waves with energies in the teens and twenties. On the 24th and 25th, the wind picks up to 22 mph from the SW, which is a cross-off, but that’s just going to blow over a flat ocean. So, what does this all mean? There’s simply no good surf on offer in this 16-day window. But don't get too down. Breaks like this that are rarely breaking don't stay that way forever. The forecast can and often does change. We just need a good swell pulse to line up with the right wind. Until then, I’d be finding something else to do. Keep the faith.

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.
