The Lowdown
G’day, Rusty here. Let’s be straight with you – this 16-day window for Trincomalee is a tough one. The outlook is pretty much flat, and the few little bumps we get are messing with cross-off winds that just won’t let up. The swell is tiny, confused, and the energy is weak. I’m looking at a long stretch of nothing much to recommend.
The first real surf recommendation is on Friday, July 31, but it’s a bit of a tease. Trincomalee is a point break that rarely breaks; it’s very sheltered and needs a decent S swell to wake up. Instead, we’ve got a small SE swell at 2ft, period 10 seconds, with a combined energy of 121 (moderate). The wind is a fresh cross-off from the WSW at 19 mph, so it’s not clean. Water temp is 84°F – about average for the time of year. This is poor surf, honestly. Not worth a paddle.
Saturday, August 1, is even smaller: 2ft from the SE, period 10 seconds, energy dropping to 88 (weak). Still cross-off winds at 19–22 mph. Sunday, August 2, drops to 1ft with energy down to 31 – really weak. The pattern continues: Monday has 1.0ft, Tuesday 0.3ft, and so on. The swell directions are all over the place – SE, S, even a long-period 22-second S swell on the 5th that gives a tiny 0.3ft wave. That’s a ghost swell. The combined energy on the 5th afternoon is 21 (weak). Nothing to ride.
There’s a brief flicker on Thursday, August 6 morning: a gentle offshore wind from the W at 9 mph, and the swell is 0.7ft from the SSE, period 8 seconds. That offshore makes it clean, but 0.7ft is barely a ripple. Energy is 8 (weak). Not surfable.
From August 7 through to August 15, it’s the same story. Swell heights stay between 0.3ft and 2ft, periods range from 8 to 22 seconds, but the wind is almost always a cross-off from the WSW at 12–22 mph. The only exception is Saturday, August 15 afternoon, when we get a light offshore breeze from the WNW at 6 mph, with a 2ft SE swell, 11-second period, energy 64 (weak). That’s the cleanest window, but the swell is still tiny.
The standout? There isn’t one. Not a single day offers a decent wave. The best on offer is probably just getting a float in the lake-like conditions. For a point break that rarely breaks, this is a normal blank run. Trincomalee just doesn’t fire with this setup. The swell is too small, the direction is poor, and the wind is never your friend. I’d say save your energy and wait for the next system.
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.
