The Lowdown
Alright folks, Rusty here. Let's have a look at what's shaping up for the Trincomalee area.
Straight up, we're looking at a pretty bleak 16-day window. The surf is tiny and underwhelming for the foreseeable future. The first real chance to even think about a paddle isn't until Monday the 11th of August, but even then, it's a struggle.
Trincomalee itself is a point break, but it's described as "rarely breaks", which tells you a lot. The swell energy is in the weak range for the entire period. You're looking at a combined swell energy of just 61 (moderate on the low end) on Monday afternoon, with a tiny 2ft swell from the SE. That's a cross-offshore wind from the WSW at 19 mph, which does keep the surface clean, but with that little energy and a short 9-second period, there's just nothing doing. The water temp is sitting at a balmy 83°, which is about average for this time of year.
Tuesday the 12th is no better. We see a tiny spike in combined energy to 137 on Tuesday afternoon, but that's from a 1.0ft, 20-second period groundswell from the SSE. That long period is good for quality, but there's no height to work with. The energy is still moderate at best, and the wind is a fresh cross-offshore at 16 mph. The swell direction from the SSE is also a poor fit for this spot, which prefers a S swell.
The pattern continues through the week. Squint at the numbers and you might see a glimmer on Wednesday afternoon the 13th with a 3ft swell from the SSE and an 8-second period. The energy hits 236, which is solidly moderate. But that's a short-period windswell, and while the wind is cross-off, the quality will be poor for a point break. It's not going to wrap in cleanly. For the rest of the week, it's the same story: tiny 2ft to 2ft swell with moderate to weak energy and persistent cross-offshore winds. It's clean but anemic.
There's a slight change in the wind on Friday the 15th. The morning has cross-offshore at 12 mph, but the afternoon turns to a light cross-shore from the NE at just 6 mph with a 2ft SSE swell and energy of 119. Still, it's just not enough.
Into the second week, the outlook doesn't improve. From around Thursday the 21st of August onward, the swell drops even further to 0.7ft to 1ft, and the combined energy plummets back down into the weak zone (20s to 80s). The winds remain mostly cross-offshore, but the whole setup is just flat. The point break needs a proper push from the south, and it's just not getting it.
There is no standout day. No best option. This is a long, dry spell for paddle surfing. For the whole 16 days, the wave heights barely crack 3ft, and when they do, the period is too short or the direction is wrong. If you're jonesing for some time on the water, the cleaner conditions and stronger cross-offshore winds on some of those afternoons might make Trincomalee Bay more interesting for a kite session than a surf session.
Stay patient, boys. The ocean will come back around.

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.
