The Lowdown

Alright, let’s get into it. It’s Rusty here.

Honestly, looking at the next 16 days, it’s a bit of a mixed bag with plenty of wind and messy conditions to wade through before we get anything worth getting excited about. The first few days are pretty ordinary, but if you’re patient, there are a couple of sessions that could be worth the wait.

The action starts Saturday the 29th, but I wouldn't paddle out. We’ve got rain showers and a stiff 25 mph cross-off wind with a weak, short-period 5 ft swell from the WSW. The energy is low (169) and it’s just poor surf. That afternoon it jumps up to a heavy 12 ft from the west with a solid 9-second period, but that wind is still howling at 28 mph and the conditions are poor. That one’s for experts only, and even then, it’s not clean.

Sunday the 30th morning is a small step forward. Trestraou picks up a 5 ft west swell (9-second period) with a clean offshore wind from the SSW at 12 mph. It’s only surfable, not great, but that’s the first real chance to get wet this period. The energy is moderate (389).

Monday the 1st of September morning has a bit more size – 8 ft from the west with a 10-second period – but the cross-off wind keeps it marginal. Not the best, but the energy is strong (1102).

Tuesday the 2nd is small and weak, dropping to 3 ft with only 103 energy. Nothing doing.

We hit a real lull from Wednesday the 3rd through to Sunday the 7th. There are waves, but the conditions are consistently poor. The swell stays small and the wind is never quite right. It’s a frustrating stretch.

Now, here’s the standout. Wednesday the 9th of September is the one to circle. Trestraou is looking good with a 7 ft west-northwest swell (9-second period) and a light 6 mph cross-off breeze from the WSW. The water temp is about average for the time of year. The energy is strong (856) and the conditions are clean. This is the best window of the entire outlook. It’s not huge, but it’s well-shaped and will have proper lines. Get on it.

That morning is the pick, because by the afternoon the wind swings onshore and it’s gone.

The rest of the second week is mostly wind-affected or small. Thursday the 10th and Friday the 11th have some size but the wind is strong offshore – clean faces but hard work paddling into. Saturday the 12th has gale-force offshore winds, which is more for kite surfing than paddle surfing. Sunday the 13th is a write-off.

So overall: a rough start, a long quiet patch, but Wednesday the 9th morning is your real shot. Don’t sleep on it.

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.
