The Lowdown

Alright, grab a coffee and listen up, this is Rusty.

First up, I gotta be straight with you: the next couple of weeks are looking pretty bleak for a proper paddle. The overall pattern is dominated by tiny swell and generally cross-off winds, which is a recipe for frustration. We’re starting with a real gap here, with no worthwhile surf on offer from the 4th of August right through the morning of the 11th. That’s a solid week of flat, blown-out conditions where the swell is barely a ripple. The combined energy sits around 5 to 11 (weak) for most of that first week, so don't even bother checking the cam.

Now, for the dedicated few, there’s a tiny glimmer on the horizon. The standout of the whole forecast is going to be on Tuesday afternoon, the 11th of August. Out at Trincomalee (a point break), the winds finally swing around to a light offshore from the WNW at 9 mph. The swell bumps up to 1 ft from the SSE, but the period is a massive 20 seconds. That’s a proper groundswell pulse. The combined energy rises to 122 (moderate). This little point is about as sheltered as it gets, so it's perfect for beginners. The long period means it could offer some surprisingly fun, peeling lines, but it’s a rare-breaks spot, so you need to be patient. The water is a warm 83°, which is about normal for this time of year.

After that, it’s a bit of a mixed bag. The morning of Wednesday the 12th of August looks messy again with cross-off winds, but keep an eye on Wednesday afternoon. The wind drops to a glassy 3 mph from the NW, and the swell holds at 1 ft from the SSE with a very long 16-second period. The energy is 156 (moderate). It’s glassy, clean, and could be a real sneaky session for the longboard.

The second week is a bit of a write-off, to be honest. From Thursday the 13th of August onward, we’re back to small, weak swell in the 1 ft to 2 ft range with cross-off winds and combined energy mostly under 100 (weak). The only other thing to note is the morning of the 15th of August, where the energy briefly hits 105 (moderate) with a 2 ft swell from the SSE, but the wind is still a cross-off 16 mph. It’s a “maybe” at best.

So, in short: don’t rush out this week. Your best bet by a mile is the afternoon of the 11th of August. If you miss that, the glassy period on the 12th afternoon is your backup. The rest is just a waiting game.

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.
