The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on offer for Trincomalee over the next couple of weeks. I gotta be straight with you – the outlook is pretty grim. The finder is showing zero good surf windows for the entire 16-day stretch, so we’re looking at a long, blank run. This is one of those times where the forecast just isn’t lining up for us. The water’s sitting at 83°F, which is about average for this time of year, so at least a dip won’t shock you, but the waves won’t be worth the paddle.
The overall pattern is dominated by a consistent cross-off wind from the WSW, but the swell is just too weak and short to do anything with. We start with Thursday afternoon, 23 July, and it’s already a write-off: a tiny 3ft SE swell with a period of only 4 seconds and a weak energy reading of 25. The onshore wind doesn’t help. Friday morning, 24 July, the swell drops to 2ft, and while the wind turns light and cross-off, the period is still a pathetic 8 seconds. This theme continues right through the weekend. By Saturday, 25 July, the swell nudges up to 3ft, and the energy climbs to a moderate 101, but the period is still short at 9 seconds, and the wind is onshore in the afternoon. Sunday, 26 July, sees the best energy of the whole run at 194, with a 3ft SE swell and a period of 11 seconds. The wind is cross-off and clean, but the finder still scores it a zero. It’s that rare point break, and it’s sheltered, so it just isn’t picking up the energy properly. It’s a consistent miss.
The following week doesn’t get any better. From Monday, 27 July, through to Friday, 31 July, we’re stuck with small, weak swells between 2ft and 3ft, with energy mostly in the 100-150 range. The wind stays cross-off and clean, but the swell is just too small and short-period to make the break work. The energy drops right off into August, with 1 August seeing a 2ft swell and energy of 63. By 2 August, it’s down to 2ft, and by 3 August, we’re scraping the bottom with a 1.0ft swell and energy of 20. The wind finally goes offshore on the afternoon of 3 August, but with a 1.0ft swell, there’s nothing to ride.
The last few days from 4 August to 7 August are a total bust. The swell stays under 1ft, with energy barely reaching 41. Even on 7 August, when we get a gentle offshore breeze and clean conditions, the swell is just 1ft with a period of 8 seconds. Nothing to get excited about. For a spot that’s rarely breaks anyway, this is a proper dry spell.
So, there’s no standout, no hidden gem, nothing to chase. The surf is flat, and the forecasts will need to change a lot before we see any action. Chin up, though – it won’t stay this way forever.
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.
