The Lowdown
Alright folks, Rusty here. Let’s break down what’s in the water for the next couple of weeks.
We’re looking at Portreath Harbour Wall, a reef setup. Right now, the water is 66°F, which is a touch warmer than normal for this time of year, so that’s a nice little bonus if you’re getting in.
Truth is, the next several days are pretty grim. From Monday the 27th right through to the morning of Tuesday the 4th of August, it’s a long stretch of junk. We’re looking at small swell, mostly around 1ft to 3ft, with a lot of cross-on or onshore wind messing things up. The energy is weak, and the periods are short. It’s just not worth paddling out for anything serious.
You’ll see a flicker of life on the morning of Tuesday the 4th of August. The wind switches to a light cross-offshore, and the swell bumps up just a little to 2ft from the WSW, with a period of 9 seconds. It’s clean. That afternoon gets even better, with a light offshore wind from the SE, 2ft of SW swell. It’s surfable, but very ordinary—just a small wave for a longboard or a fun log. Nothing to get hyped about.
The real standout, and the only one worth circling on the calendar, is the morning of Friday the 7th of August. We’ve got a moderate offshore wind from the SE, cleaning up a 5ft swell from the NW. The energy is moderate, and the conditions are described as “expect good surf conditions.” The wind is offshore, the swell is there, and it’s the best call of the whole run. That’s your window. It’s a fairly consistent break, but it can get crowded, so expect company.
After that, Saturday the 8th of August looks big and messy. The swell hits 8ft from the W with strong energy, but the wind is a fresh cross-onshore, and it’s lumpy. That’s expert territory at best, and honestly, with that much wind, the setup might be more interesting for kite surfing than paddle surfing. Sunday the 9th is similar, with 7ft of WNW swell but still ugly winds.
The rest of the second week is a mix of onshore and cross-off winds, with swell dropping back to 4ft to 5ft, but the energy is still moderate. Nothing else stands out as a must-surf.
So, to wrap it up: the first week is a write-off. The morning of Friday the 7th of August is your best bet. It’s not a monster swell, but the offshore wind and clean conditions will make it fun. Don’t expect much else.
Rusty.
