The Lowdown

Alright folks, Rusty here. Let’s talk about what’s coming up for Trestraou. The next couple of weeks look pretty average, with only a couple of windows that might get the heart beating a little faster. Let’s start with the pattern.

The first session worth paddling out for is super early in the run. Saturday morning, September 5th. We’re looking at a clean, 5ft swell from the WNW with a period of 11 seconds, and the wind is light out of the north, blowing straight onshore. That period is decent, giving the waves some shape, but because the wind is on it, it’ll be a bit bumpy. Still, the combined energy is moderate, so there’s some push there. The water is a touch warmer than normal for this time of year, sitting around 65°, so that’s a nice little bonus.

Now, the one standout in the whole 16-day window is Wednesday, September 9th, first thing in the morning. This is the best we’re going to see. The swell is 6ft from the WNW with a 9-second period, nothing too wild, but the wind is a gentle offshore breeze from the WSW, and the conditions are clean. This is the one to circle on the calendar. It’s not a huge day, but it’ll be the cleanest, most fun wave of the whole stretch. The break is a little sheltered, so it’ll handle that west-northwest direction well.

After that, it’s a grind. We get a few more looks, but wind and swell direction just don’t click. Saturday morning, September 12th is another early call with a 6ft groundswell from the WNW, period of 9 seconds, and a light offshore from the southwest. The energy is moderate, and the wind is just a slight air, so it’ll be clean. That’s a good option, but the swell is a touch above 5ft, so it might be a bit much for beginners. It’s a solid, clean wave for the rest of us.

The rest of the fortnight is filled with onshore and cross-shore winds, short period choppy stuff, and a lot of “poor surf” conditions. The swell drops off significantly after that first week, with most days seeing 2ft to 4ft of weak, short-period slop. The second week, from September 14th onward, is just a write-off with nothing worth getting wet for. It’s a long dry spell.

So, bottom line: Don’t hold your breath for most of this. The only real standout is the morning of Wednesday, September 9th. That’s your best bet for clean, fun waves. Saturday the 12th is a solid backup. Otherwise, it’s a quiet period for Trestraou.

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.
