The Lowdown

Alright, Rusty here with the lowdown for Trestraou over the next 16 days. We’ve got a slow start and a few windows that are worth getting wet for. Don’t get too excited early on, though; the real quality is hiding in the back half.

First up, Monday, September 7th, we get a west swell at about 5 ft, with moderate energy. There’s a cross-off wind, so it’s clean but nothing special. The water is around 64°, which is normal for the time of year. That afternoon, the swell stays around 6 ft, but a cross-shore breeze puts a little chop on it.

Tuesday the 8th is blown out completely by a strong cross-onshore wind. The swell is a mess, and it stays that way through Wednesday and most of Thursday. We get a few clean windows on Friday and Saturday mornings, but the swell is tiny, from 2 to 3 ft. It’s rideable but gutless.

There’s a dry spell after that until we hit Tuesday, September 15th. That morning is our first real standout. The wind is glassy, a dead calm from the northeast at 3 mph, and we get a nice groundswell at 5-6 ft from the WNW with a long 12-second period. Combined energy is up there, and the waves will be clean and lined up. That long period groundswell will punch through, giving you good shape, but it might run a bit straight at the beach. The afternoon gets blown out by onshore wind, so get in early.

Wednesday morning, September 16th, is another good option. We have 5 ft of WNW swell with an 11-second period, and a light offshore wind from the SSW at 12 mph. Clean conditions and plenty of push.

Now, September 17th, Thursday, is for the big-wave crew. We’ve got a serious 11-12 ft WNW groundswell with strong energy (2919). The wind is a cross-off at 19 mph, so it will be clean but heavy. That’s expert territory, all the way.

The weekend of the 19th and 20th is also promising. Saturday the 19th brings 7-8 ft west swell with moderate, clean wind. Sunday morning, September 20th, is the other standout: a 8 ft WNW groundswell, 11-second period, and a nice gentle offshore wind from the SSW. Clean, powerful, and the model says “very good surf conditions.” Get on it early.

After that, onshore winds from the north move in on the 21st and 22nd, and the run is over.

The bottom line: the first week is weak and rough. The best windows are the morning of September 15th (glassy, 5-6 ft) and the morning of September 20th (clean offshore, 8 ft, killer conditions). September 17th is a big-wave day only. Set your alarm and check the tide.

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.
