The Lowdown

Alright folks, Rusty here. Let’s take a hard look at what’s coming for the next couple of weeks, and I gotta be straight with you – it’s a rough stretch. The only break on the radar is Trestraou, and it’s a sheltered spot, so we’re pretty limited to what we can get.

The strong energy from the WNW direction is trying to push in, but the wind and the timing are just not playing nice. We’ve got a long wait for anything that even glimmers with potential. The water is a touch warmer than normal at 65°, running about 3° above the long-term average for this time of year.

Our first real chance comes on the morning of Friday the 11th. The swell hits 5 ft from the west with a 10-second period, and the combined energy is moderate at 480. The wind is light and cross-offshore, so the surf will be clean. It’s a solid option, the best of the whole run, but don’t expect perfection – the rating is only fair.

The following morning, Saturday the 12th, drops to 3 ft, and the energy is weak at 144. The wind is light and cross-off but the surf quality is just poor. Skip it.

We get another pulse on Sunday the 13th – 5 ft and 5 ft across the day from the WNW with a period of 11 seconds. The energy is strong (599) and the surf is clean in the morning, but the wind picks up and the afternoon gets chopped. It’s a come-and-go day.

The next real standout is a long way off, on the morning of Friday the 18th. The swell is tiny at 3 ft, but it’s a 12-second period and the wind is offshore and light. The energy is moderate (346). The surf is clean, but it’s small. Worth a look if you’re desperate.

After that, Monday the 21st has a 4 ft swell from the WNW with a very long 12-second period, and the wind is cross-off. The energy is moderate (350). It’s clean, but the quality is still poor for the size. Not a standout.

The last whisper of decent motion comes on the morning of Wednesday the 24th – 3 ft, a 12-second period, and glassy conditions with the wind from the SSE. Combined energy is moderate (320). It’s clean, but again, it’s small.

The rest of the 16 days is a write-off. The wind is consistently onshore, cross-shore, or just too strong, and the surf quality is poor. The setup at Trestraou is a beach-and-reef, and with the strong winds and lumpy conditions, honestly, this looks more interesting for a kite surfer than a paddle surfer for most of the run.

The best bet is absolutely the Friday morning of the 11th. That’s the one to point your car at for a clean, fun session. The rest is just filler.

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.
