The Lowdown

Alright, Rusty here. Let’s break down what’s happening for this stretch of coastline.

It’s a pretty slow start for the first week and a half. From Thursday the 10th through the middle of the month, we’re looking at mostly small, weak swell and wind that’s often cross or cross-onshore, keeping the surf messy. A few mornings clean up, like Saturday the 12th morning and Tuesday the 15th morning, but the swell is tiny—around 2 to 3 feet—so not much to get excited about. The combined energy is low, mostly under 200 (weak), so you’re looking at dribbly, weak waves.

Then we get a bit more size on Sunday the 13th with a 5-foot swell from the WNW, but the wind is still cross-shore, so it’s a bit of a letdown. Energy bumps up to 551 (moderate), but it’s still marginal. The following week stays frustrating: a lot of onshore wind from the north, especially strong on Wednesday the 16th with 22 mph winds and 7-foot swell, but it’s a choppy, blown-out mess. Energy hits 683 (moderate-strong), but you wouldn’t want to be out there unless you’re on a kite.

The real standout, and I mean the absolute gem in this 16-day window, is Sunday the 20th. We’ve got a solid 5-foot groundswell from the WNW, and the period is a very long 16 seconds. That’s proper energy rolling in—combined energy is a massive 2108 (strong). The morning is glassy, with a light 3 mph wind from the NNW, so the surface will be clean as a whistle. This is the kind of day that has excellent surf conditions for experienced surfers. The long period will make the waves powerful and well-shaped, but it might be a bit too straight for the beach break here—better suited to a point or reef. The 8-foot afternoon swell is big and heavy, only for the experts, and the wind swings onshore, so the morning window is your only chance.

The following Monday the 21st has a decent 6-foot swell from the WNW with a 12-second period, and the wind is light cross from the WNW, so it’s still rideable, but not as clean as Sunday. Energy is 902 (moderate-strong). After that, the surf drops off again, with weaker swells and stronger cross-onshore winds returning through the end of the month.

So, if you’re picking your days, Sunday the 20th is the one to circle. It’s the only true standout with glassy conditions and a proper, long-period groundswell. The rest of the run is mostly a write-off.

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.
