The Lowdown
Alright, let’s get into it. I’m just gonna be straight with you – we’re looking at a pretty grim run here for the next couple of weeks. The finder is telling me there’s nothing good on offer at all, which is a real bummer, but it happens. The only spot in the game is Trincos, a point break that’s marked as “rarely breaks,” so we’re already fighting an uphill battle. The water temp is sitting at 83°, which is bang on average for this time of year, so no surprises there.
The whole 16-day window is a blank. We’re talking about a solid two weeks with no real surf to get excited about. The wave energy is tiny – you’re looking at swell heights hanging around 1 ft to 1 ft with a short, weak period of 8 to 10 seconds. The combined energy readings are all under 100, mostly in the 20s to 80s, which is just pathetic. It’s like a lake out there. The wind is mostly a cross-off from the WSW at 12 to 19 mph, which would normally be fine, but with no swell to work with, it’s just blowing over flat water.
There’s a tiny bump around the 26th of July, where the swell ticks up to 3 ft and the period hits 11 seconds, giving us a combined energy of 186. That’s the best it gets, but it’s still “poor surf conditions” across the board. That’s a 3 ft SE swell, but with the wind staying cross-off from the WSW at 12 mph, it’s clean but gutless. Not worth paddling out for.
The 28th of July afternoon shows a bit more energy, with 4 ft from the SE and a 10-second period, pushing the combined energy to 452. That’s the most oomph we see, but the wind picks up to 16 mph cross-off, and the report still says “poor surf conditions.” It’s just not lining up.
For a break that rarely breaks, this is a pretty normal dead period. The setup is a point, so it needs a decent swell direction and size to fire, and we’re not getting it. If you’re desperate, you could sit on the beach and watch the ripples, but honestly, the wind and tiny swell make this look more interesting for kite surfing than trying to paddle a surfboard.
Keep your hopes up – forecasts can change, and it can’t stay this flat forever.

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.
