The Lowdown

Alright folks, Rusty here. Let’s look at the stretch ahead for Trestraou. It’s a bit of a mixed bag, but we’ve got a few moments that could be worth a paddle.

Right from the get-go, it’s a tough start. The water is sitting at 65.1°, which is a touch warmer than normal for this time of year, so you can leave the thickest rubber at home. But the surf? Poor. For the first few days, we’re looking at small, weak west swell with a combined energy of only 162 (moderate) on Tuesday afternoon, and it’s got a cross-onshore wind on it. Not worth getting wet for.

Wednesday morning the 2nd offers a clean 2.6ft west swell with offshore wind, but it’s tiny and the energy is weak (80). It’s more of a longboarders’ dream than a proper session. That pattern of small, clean but weak surf continues through Thursday and Friday, with the swell building a touch to 4.6ft-4.9ft on Thursday and Friday, and the combined energy climbing into the 200-300 range (moderate). The wind is cross-offshore, so it’ll be clean, but the quality is still rated as poor. It’s surfable, just nothing to write home about.

Saturday the 5th and Sunday the 6th see a shift in wind direction, bringing in a cross-onshore breeze and a choppy surface. The swell drops right back down to 2.0ft on Sunday morning, with a weak energy of 102 (moderate). It’s not looking good.

Now, Monday the 7th is where things get interesting. A long-period groundswell from the west starts to show up. The morning is clean with a 2.0ft, 13-second period swell, but it’s still weak (177 energy). The real story is Monday afternoon. The swell jumps to 5.2ft from the west, with a 12-second period, and the combined energy hits 710 (strong). The wind is cross-shore, so expect a bit of chop, but there’s some real power in the water. Not a standout though, because the wind isn’t ideal.

The real standout is Tuesday the 8th. The morning is clean with a solid 7.2ft west swell, but the energy is a huge 735 (strong). By the afternoon, it’s even bigger: 8.2ft from the west-northwest, with a combined energy of 1083 (very strong). This is expert territory at that size. The wind is cross-offshore, so the waves will be clean and powerful. This is the best on offer in the whole outlook. If you’re experienced, this is your window. Just be aware the period is 9 seconds, not a super-long groundswell, so it’ll be a bit more punchy than drawn-out.

After that, the swell drops off again. The 9th still has some size (5.9ft-6.6ft) and clean cross-offshore wind, but the energy is dropping. The 10th through the 13th is a write-off: small, weak, and mostly cross-onshore or onshore winds. A real lull.

Then, there’s a promising but less certain window in the second week. Monday the 14th has a 5.2ft-5.6ft west swell, and by the afternoon it’s glassy. The energy is moderate (355). It’s surfable, but not a standout.

The second standout comes on Tuesday the 15th. The morning session is clean, with a 6.6ft west-northwest swell, a 10-second period, and a combined energy of 810 (strong). The wind is light offshore from the southwest. This is a good, solid swell with clean conditions. It’s not quite as big as the 8th, but it’s still a proper session. The afternoon turns choppy with a cross-onshore wind, so get in early.

The 16th fades out with small, clean but weak surf.

For the whole period, Trestraou is a sheltered spot, and the optimum swell direction is west-northwest. The big swells on the 8th and 15th are coming from that sweet spot. The crowds are listed as “sometimes,” so you might have some company, but it won’t be a circus at these sizes.

On the 8th, with that 8.2ft swell and strong energy, the beach break setup might actually be more interesting for kite surfers than paddle surfing if the wind cooperates, but at Trestraou, it’s a sheltered spot, so it’s likely still surfable.

Overall, the first week is a slow burn with one killer day on the 8th. The second week offers a solid morning on the 15th. Don’t hold your breath for the rest.

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.
