The Lowdown

G’day, Rusty here. Let’s be straight with you – for the next 16 days, the surf scene around Trincomalee is pretty flat. There’s no real swell to get excited about, so don’t be in any rush to grab your board. The overall pattern is small, weak, and honestly, pretty frustrating for a surfer. It’s a long stretch of days with hardly any wave energy, so if you’re a paddler, patience is the name of the game.

Looking at the first spot, Trincomalee itself – it’s a point break and rarely breaks, so we’re already up against it. The swell is tiny, mostly around 0.7 ft to 2 ft, coming from the southeast or south-southeast, with periods between 7 and 9 seconds – that’s short-period, weak stuff. The combined energy is mostly in the low double digits, like 8 to 46, which is weak. There’s no power behind it. The water temperature is about average for this time of year, nothing unusual. The winds are mostly cross-off from the west-southwest, blowing at 15 to 22 mph, which keeps things clean but doesn’t help the tiny waves. Crowds are only sometimes an issue, but let’s be real – there’s nothing to fight over.

Wednesday the 16th and Thursday the 17th are both a write-off: 0.7 ft to 1 ft, weak energy, poor surf. Friday the 18th shows a tiny bump to 2 ft, period 9 seconds, energy up to 46, but it’s still poor. Saturday the 19th has a bit more energy (42) in the afternoon, but still only 1 ft and short period. The whole first week is a wash – day after day of “poor surf conditions” in the data.

The second week isn’t much better. Monday the 21st has a 0.7 ft swell with a 16-second period early morning – that’s a very long period, but the height is so small it won’t break properly here. Energy hits 41, but it’s more of a tease than anything. The standout moment, if you can call it that, is Saturday the 26th afternoon: combined energy jumps to 115 from a 1 ft, 20-second period swell from the south. That’s moderate energy, and the period is seriously long, but at a point break like Trincomalee, that might actually line up okay. Still, it’s only 1 ft – you’d be fighting for a knee-high wave. Tuesday the 29th afternoon shows 3 ft swell from the southeast, period just 4 seconds (very short, choppy), energy 44, but it’s glassy – that’s the only size worth mentioning, but the period is terrible. Wednesday the 30th and Thursday the 1st of October stay tiny and glassy, no real action.

There’s a massive gap in any quality surf here. The whole 16-day window is a bust. For a spot that rarely breaks, this is more normal than you’d hope. Keep an eye on the 26th afternoon as the most promising, but don’t hold your breath. If the wind picks up, the bigger days might be more interesting for kite surfers than paddle surfers.

Stay patient, mate.

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.
