The Lowdown

Alright, Rusty here, and I’ve got a look at the next two weeks for Trestraou. Let’s be straight with each other – this run is a struggle. We’re looking at a long gap with very little to get excited about, and even when the swell shows up, conditions are fighting it.

The water is sitting at 66°F, which is a touch warmer than you’d normally expect for this time of year. That’s a small comfort, because the surf itself is a tough sell for a long stretch.

The first real chance of anything rideable comes on Thursday, August 27th. The morning offers a gentle offshore wind from the SSW, with a 4ft swell from the west, period of 9 seconds. The combined energy is moderate at 300, and it’s described as surfable but very ordinary. It’s not a standout, but it’s the first time we get a clean look at the water. The afternoon turns messy with a fresh cross-offshore breeze, so the morning is your window.

Friday, August 28th, looks better on paper. The morning has a moderate offshore from the SSW with a 6ft west swell (8 seconds), and the energy jumps to 628. The surf is described as marginal, and the tide might be a factor, but it’s the cleanest we’ve seen. The afternoon holds a 7ft west swell with a fresh offshore, energy at 656. Still marginal, but if you’re an experienced surfer, this is the best of a tricky bunch.

Then things get wild. Saturday, August 29th, rolls in with a big 12ft west-northwest swell, period of 10 seconds, and very strong energy readings of 2733 in the morning and 2021 in the afternoon. The wind is strong cross-offshore, making it clean but heavy. This is expert-only territory – way too big for beginners. The swell is long period enough to be a proper groundswell, but at a beach break like Trestraou, it could be closing out and tricky. If you’re a big-wave charger, you’ll be looking at it, but for most, it’s a day to watch from the sand.

After that, the window closes fast. From Sunday, August 30th, through to the end of the forecast on September 4th, the surf drops off quickly and the winds turn onshore or cross-shore, making for consistently poor, choppy conditions. The energy dwindles, and the swell heights are small and weak. It’s a blank run to finish.

So, the standout window is really the morning of Friday, August 28th, with a 6ft to 7ft west swell and clean offshore wind. The Saturday big swell is for experts only. For the rest of the run, the wind and small surf just don’t cooperate. Keep your expectations low, and if you’re a kiter, those big, windy days on the 29th might be more interesting than paddle surfing.

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.
