The Lowdown
Alright, let me tell you how it’s looking. Honestly, I wish I had better news, but right now there’s a whole lot of nothing on the menu around here. The whole 16-day window is a flat spell. First recommendation – or rather, the first chance to even talk about a break – comes from Trincomalee, but it’s a long, quiet stretch. From now until at least the 26th of August, there’s basically nothing worth paddling out for. Then from that first session, it just keeps going with barely a ripple for days.
So, here’s the deal. Trincomalee is a point break, sheltered as they come, and it rarely breaks. This stretch? It just doesn’t have the juice. The combined swell energy barely creeps into double digits, peaking at 93 for a brief moment on the 2nd of September – weak at best (93). We’re looking at tiny swell from the southeast, mostly around 1 ft to 2 ft, and a short, weak period of 8 to 9 seconds. That’s small, weak, and won’t wrap in properly. On the 30th of August, Sunday afternoon, you get a brief moment with offshore wind from the west at 9 mph, which would clean it up, but the swell is still just 1 ft, so it’s glassy and flat. On the 3rd of September, Thursday afternoon, same story – gentle offshore, clean, but only 2 ft.
Unfortunately, the water temperature here is 84°F which is normal for this time of year – not cold, not warm, just average. But there’s no power behind it. There is no standout. No day worth highlighting as good. The best you can hope for is a tiny, clean little wave on a longboard on the 30th of August or the 3rd of September. But it’s not going to be exciting, and the crowds could pop up since it sometimes gets busy. Still, with waves this small, there won’t be much competition.
In short, this is a grim outlook. It’s a flat run that’s pretty normal for this area when the swell just refuses to show. Forecasts can change, so keep an eye out, but as of now, leave the board at home.

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.
