The Lowdown
Alright folks, let’s call it what it is – a dead spell for the next couple weeks. There ain’t a single decent wave in this whole 16-day window. Nothin’ worth gettin’ wet for.
We’re talkin’ Trincomalee, a point break that’s a beginner’s spot. The problem is, it *rarely breaks*, and this forecast proves it. The swell is tiny, barely reachin’ 2ft at best. It’s comin’ from the southeast, but this place wants a south swell, so it’s all wrong.
From Wednesday the 19th right through the end of August, you’re lookin’ at waves from 0.7ft to 2ft. The energy is weak, never crackin’ triple digits – numbers like 33, 15, even 9. The period is mostly short and weak, 8 to 9 seconds, so there’s no grunt. Winds are a steady cross-off from the WSW, blowin’ 12 to 19 mph, keepin’ it clean but there’s just nothin’ to surf.
There’s a little tease on Saturday the 29th and Sunday the 30th. Saturday afternoon we get a brief offshore from the NW at 9 mph, and Sunday afternoon a light offshore from the WNW at 6 mph. That’s perfect wind for a point – glassy as glass. But it’s still on a 2ft swell with energy only 32 to 47. You’d be sittin’ out there with no push.
Water temp is about 83°, right where it should be for this time of year.
For a break that’s already inconsistent, this is a long, flat stretch. It ain’t unusual for the area to go quiet, but 16 days with no surfable waves is a tough go. Might be time to dig out the kite gear – with those clean cross-off winds and ankle-biters, that’s where the fun’s at, not on a surfboard.

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.
