The Lowdown

Alright folks, Rusty here. Let's have a look at the local outlook for Trestraou. It's gonna be a bit of a slow burner this time, but there's a couple of windows that could be worth your time.

Right now, it's flat with a messy cross-onshore breeze, so don't even bother. We've got a few days of small, cleanish surf coming in from Tuesday the 25th. The wind will be light offshore or cross-off, which is a big plus for the surface, but the swell is tiny – we're talking knee-to-waist high at best. The energy is on the low side. It's nice for a longboard or a beginner's session, but nothing to write home about.

The first real standout arrives on the morning of Saturday the 29th of August. We've got a solid pulse of swell, with a wave height of about 8 feet. That's a bigger, powerful, west-northwest swell. The wind is clean cross-off. This is definitely one for experienced surfers only, as it's getting a bit hefty. The period is a short 8 seconds, so expect it to be a bit lumpy and on the faster side.

The surf drops off after that, but keep an eye on the forecast for the start of September. The morning of Sunday the 6th of September is promising, with another 8-foot swell from the west-northwest, and the energy is through the roof. The wind is a moderate cross-shore, so it won't be glassy. This is another big, powerful swell, definitely expert territory, and the period is still short at 9 seconds.

The biggest potential for the whole forecast is on the morning of the 8th of September. We're looking at a 10-foot swell with a very long period of 15 seconds. That's a serious amount of water moving. This is a groundswell, mainly for the experts. The wind is a moderate cross-shore, so it won't be perfect, but the sheer size and power will be incredible. Remember, long-period swell like this can be a bit tricky on a beach break, but Trestraou is a beach-and-reef setup, so it might offer some standout peaks. This one is still over a week away, so keep your fingers crossed.

The water temp is about average for the time of year, nothing unusual.

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.
