The Lowdown
Alright folks, Rusty here. Let’s talk about the surf outlook for Portreath Beach.
First up, the honest truth – we’ve got a long, bleak stretch ahead. The forecast shows a real dry spell from now until the 6th of August. That’s a solid week or more of tiny, messy waves that aren’t even worth a paddle. The combined swell energy is almost non-existent, hanging out in the double digits, which is weak. The wind is mostly onshore or cross-onshore, making a mess of the small swell. It’s a tough run.
Then, things finally get interesting. The standout window is the 7th and 8th of August, and it’s the 8th of August that’s the real gem. On the morning of the 8th, we’ve got a solid 7ft swell rolling in from the west, with a period of 8 seconds. The combined energy jumps to 816 (moderate to strong), which is a proper kick. But the best part? The wind is glassy. That’s right, flat calm. This is going to be clean, lined-up waves for the intermediate crew. The swell is over 5ft, so it’s a bit too much for beginners, but for the rest of us, it’s a morning of pure magic. Crowds are likely at Portreath Beach, so get there early.
The morning of the 7th of August is a bit of a warning. The swell is pumpin’ at 8ft to 10ft (combined energy 924-1247), but it’s onshore and messy. That’s expert-only territory, and even then, the quality is marginal. The 8th is the day to circle.
After that, the 9th of August cleans up a bit with a 4ft west swell and a clean cross-offshore breeze, but it’s a drop in energy (171 combined). It’s surfable, but nothing special. The rest of the second week fades back into onshore slop and small swell.
Overall, the best bet is the morning of the 8th of August. Glassy, chest-to-head-high waves and a westerly swell direction matching what the spot wants. That’s the one.
Rusty.
