The Lowdown

Alright, Rusty here. Let's have a look at what's on offer for our region over the next couple of weeks.

Honestly, it’s a tough stretch ahead for Trestraou. Looking at the whole 16-day window, there's not a single day that I’d be stoked to paddle out. We've got a long, flat spell with no real surf to get excited about. The wave energy is just too weak for most of it, and when there is a bit of size, the wind and conditions are all wrong. We're looking at a blank run that's pretty much the whole way through, which for this area is just how it goes sometimes.

Starting off on Sunday the 26th of July, we’ve got some WNW swell pushing 5 ft to 6 ft, but it’s short-period windswell at just 7 seconds. The wind is a fresh 19 mph cross-off and cross-shore, churning up a lumpy cross-chop. The combined swell energy is moderate at best (225-327), but the surf quality is poor. It’s just not clean enough to be fun.

Monday the 27th sees the swell drop a touch to 5 ft with a slightly better 9-second period, but it's still cross-shore with a 9 mph breeze. The energy drops back (355) and the conditions are still choppy. Not worth the drive.

From Tuesday the 28th right through the first week of August, the swell bottoms out. We’re looking at tiny waves, anywhere from 1.0 ft to 4 ft, mostly onshore or cross-onshore winds, and the combined energy is weak to low-moderate. The water temp is about average for the time of year. There's just no clean, rideable swell on the cards.

Even when we get a late burst on Sunday the 9th of August, with a WNW swell jumping to 6 ft and a combined energy of 561 – which is strong – the period is only 9 seconds and the wind is a moderate cross-shore, creating a messy cross-chop. And then on Monday the 10th, it's 7 ft (591 energy) but the wind is straight onshore from the north. That’s too big and messy for a good time, and with short period, the shape will be junk.

There is one small window of clean conditions on Wednesday the 29th of July morning with a light cross-off wind, but the swell is only 2 ft. You’d be bobbing around on a knee-high wave with nothing behind it (68 energy). Same again on Saturday the 1st of August morning, tiny and clean (2 ft, 45 energy). On Friday the 7th of August morning we get clean conditions with a 5 ft swell from the north, but the period is a shocking 5 seconds—that’s just wind chop, not a wave you can surf properly.

To be blunt, there are no standouts in this outlook. The best you could hope for is a small, clean morning session on that 29th of July for a longboard, but the energy is just too weak to call it any good. Everything else is a write-off. Sometimes the ocean just takes a holiday. Things can change, but for now, I'd say leave the board in the van.

Rusty.

Information about the Trestraou Surf forecast

The above surf forecast table for Trestraou provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trestraou can be found by selecting the local surf guide option on the grey menu. Our Trestraou 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 (Trestraou) 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 Trestraou 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.
