The Lowdown
Alright, let me be straight with you. I’ve looked over the charts for Trincomalee, and to be honest, the next 16 days are looking pretty flat. There’s no real swell coming our way that’s going to get the heart pumping. The forecast is a long, quiet stretch.
Right through from Wednesday, 22 July, all the way to Thursday, 6 August, the waves are just tiny. We’re looking at a swell height of 1 ft to 3 ft at best, and that’s coming from the southeast. The period is short, mostly 8 to 10 seconds, so there’s no grunt in it. The energy is weak, with combined energy values rarely climbing above 100 (24 to 241 is the range, and even the highest number is just a pulse of weak energy). The wind is often cross-off or cross-on, and there’s a stretch where it’s blowing fresh, which is messy.
The one spot we’ve got is Trincomalee itself. It’s a point break, but it rarely breaks, and it’s very sheltered. The swell direction is from the southeast, but the optimum swell direction for this spot is from the south, so the angle is off. The water temperature is about average for this time of year, nothing unusual.
For a beginner, these tiny waves might be okay for a splash, but the conditions are poor across the board. The wind is often a gentle to moderate breeze, but when it’s onshore, the surface gets choppy. There’s a brief moment around Friday, 31 July, into the afternoon when the wind goes offshore from the northwest, but the swell is still only 2 ft and 10 seconds. It’s clean, but it’s not going to be a standout.
There’s a little more energy on Sunday, 26 July, and Monday, 27 July, with swell hitting 3 ft and a period of 11 seconds, which is a bit better, but the energy is still only moderate (241). The wind is cross-off, so it’s clean, but the waves are still tiny and poor. It’s just not enough to get excited about.
Honestly, this is a blank run. It’s a normal pattern for this area when the swell is this sheltered. We’ll have to wait for the forecasts to change. There’s nothing here that’s even close to a standout.

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.
