The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s heading our way for the next couple of weeks.
To be straight with you, the next 16 days are a real struggle. There’s nothing on the cards that I’d call a proper surf session. The whole run is a flat spell with only tiny, weak energy and very poor surf conditions day after day. We’re looking at a long, boring gap right from the start, with no worthwhile waves to get excited about.
The first few days – from Wednesday the 29th of July through to the weekend – offer up tiny swell around 2 ft at best, coming from the SE with a period of 10 seconds. The wind is a fresh cross-off breeze, which keeps the water clean, but the combined energy is weak, sitting between 98 and 156 (moderate at best). Honestly, it’s just not enough to push a surfboard. The wind stays strong and cross-off through the end of the month, and the swell drops off even further by the start of August.
By the 1st of August, the swell is down to 2 ft, and by the 2nd of August it’s barely 1 ft. The wind does go offshore on the morning of the 2nd, but the wave energy is a measly 29 (weak). Not worth paddling for.
The entire first week of August is a write-off. Swell heights drop to 1.0 ft, then 0.7 ft, and by the 4th of August we’re looking at 0.3 ft with a combined energy of just 5 (weak). The water gets glassy in the afternoon on the 4th, but there’s nothing to ride. The following days are similar – tiny, weak, and poor.
There’s a slight uptick around the 11th of August, with swell nudging back up to 2 ft from the SE, and the period stretching to 11 seconds. The combined energy hits 162 (moderate) on the morning of the 11th, and even 253 (moderate) on the afternoon of the 12th. But the wind is still a fresh cross-off breeze, and the surf conditions are still rated as poor. The direction is SE, which is not the optimum for this spot, and the break itself is very sheltered and rarely breaks. It’s just not going to come together.
The only break on the list is Trincomalee. It’s a point break that’s beginner-friendly, but it rarely breaks, and when it does, it’s very sheltered. On the plus side, the water temperature is sitting at 84°, which is normal for this time of year. The crowds are only sometimes an issue, but with no waves, that’s a moot point.
The bottom line? There’s no surf to speak of in this 16-day window. The models are showing a flat, weak pattern that’s typical for this area at this time of year. It tends not to stay this poor forever, but right now, we’re in a dry spell. Keep an eye on the charts, but don’t hold your breath.
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.
