The Lowdown
Alright folks, Rusty here. Let’s have a good look at what’s coming up for us around Portreath Beach. I’ll be straight with you – it’s a bit of a slow start and we’ve got a long patch of frustrating conditions to get through before we see the light.
For the first week and a half, the surf is pretty grim. We’re looking at a solid run from Monday the 10th right through to the morning of Thursday the 20th where there’s no surf worth riding. The swell is around, but the wind is just all wrong, mostly cross-onshore or onshore, keeping everything choppy and messy. Sure, there are a few mornings and afternoons with clean offshore winds on the 11th and 21st, but the swell is tiny—around 1 ft to 2 ft—with weak energy and short periods. That’s not going to get you excited.
What is interesting is that the water temp is about average for this time of year, so no surprises there for the first few sessions.
Now, the one standout in this window is the morning of Monday the 25th of August. That’s the one to circle on the calendar. We get a solid 5 ft swell from the WSW with a moderate 8-second period, and the combined energy is up strong. The wind is light and offshore from the NE, which means clean lines. The break is fairly consistent and exposed to the NW, but with the swell direction coming from WSW, it could wrap in nicely. Keep in mind that the period is moderate, so don’t expect super long lulls – just solid, workable waves. Not for beginners though, 5 ft is getting up there. There might be a few others out, as the spot can get crowded, but for that quality? Worth paddling out.
Before you get too excited, the swell energy in the lead up on Thursday the 24th afternoon shows a bit more size at 6 ft but it's coming from the SW with a poor short 6-second period and cross-shore wind. That’s gonna be lumpy and not the same quality as the Monday morning.
So, hang tight, let the rubbish wind days pass, and get ready for that 25th. The near-term calls are solid, but that long-range Monday is a promise worth keeping an eye on. The setup is better for paddle surfing than kiting through most of the period due to the consistent onshores.
Rusty.

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).
