The Lowdown

Alright, Rusty here. Let’s have a look at what’s cookin’ for us.

Right off the bat, I gotta be straight with you – the next week and a bit is gonna be a tough watch. We’re looking at a long gap of poor surf, starting now and stretching all the way through to the end of the first week of September. For a solid eight days, the waves are just not cooperating. Low energy, messy winds, and the conditions are just *sad*. The water at Trestraou is sitting at a touch warmer than usual for the time of year, around 67°F, but that’s about the only nice thing I can say. The swell is tiny, the period is short, and it’s mostly cross-shore junk. There’s a few moments of clean offshore wind here and there, but the swell just isn’t there to back it up. A 2ft wave on Thursday morning might look glassy with a SW offshore, but it’s weak and won’t have any push.

The first real glimmer of hope comes on Saturday the 29th of August. The swell starts to build, with a 6ft pulse from the WSW on Saturday morning. The wind is blowing a solid offshore from the SSW at 18 mph, so it’ll be clean, but that’s a fresh breeze and the period is only 7 seconds. That’s a short, choppy, windswell, really. The combined energy climbs to 281 (moderate). By the afternoon, it’s a 7ft swell with a WSW cross-offshore, but the wind is howling at 25 mph. That’s expert territory size-wise, and the strong breeze is going to make it a battle. It’s more of a wind-kite session than a paddle board day.

We finally get a *marginal* nod on Sunday the 30th of August. The morning shows a 7ft groundswell from the west with a nice 10-second period and a clean, fresh offshore wind from the SSW (18 mph). The combined energy hits 824 (strong). This is the first real window where you could get a wave. It’s still big for beginners, but for an intermediate or better surfer, that offshore wind on a west swell at Trestraou could be fun. The afternoon drops back to 6ft and turns stormy with a risk of thunderstorms.

After that, it’s back to the junk show. Monday the 31st sees an 8ft west-northwest swell with huge energy (1156), but the wind is a messy cross-shore. It’s going to be a washing machine, and honestly only for the crazy crew.

The real standout, the one to circle on your calendar, is Monday the 7th of September. This is the only day that gets a “very good surf conditions” nod. The morning session is looking proper. We’ve got a solid 8ft groundswell from the west, with a long 11-second period. The wind is a gentle offshore breeze from the southwest (9 mph). That’s clean, glassy, and powerful. The combined energy is a massive 1197 (very strong). That is a legit swell. The size is big, so beginners beware—this is for the crew who know what they’re doing. That long period means it will have some serious punch, and the gentle offshore will make for some pristine walls all day long. This is the pick of the whole two weeks, no doubt. The afternoon gets a bit messy as the wind swings cross-shore and the swell hits 8ft, so get out there early.

So, in short: forget the first week and a half. The one true standout is Monday September 7th, early morning. That’s the one.

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.
