The Lowdown
Alright, Rusty here for the imperial version. Let’s break it down.
Honestly, I’m not going to sugarcoat it – this is a pretty grim stretch for Portreath Beach. The whole 16-day window is a write-off for decent surf. There’s a complete blank to start, and the models just aren’t giving us any clean, rideable waves. The swell is there, but it's a mess. The wind is all wrong, and the quality just isn’t there.
The first sniff of anything that wouldn’t have you paddling straight back out starts on the 5th of September. Saturday morning we’ve got a 5ft swell from the WNW with a long period of 12 seconds, which is a proper groundswell (combined energy of 550 – moderate). But the wind is light and cross-shore. It’s marginal, the kind of day you might get a couple of bumpy ones if you’re really keen, but it’s not a standout. The afternoon drops to 4ft from the W with an 11-second period, still light cross-shore. It’s only a score of 1 out of 10, so keep expectations low.
The real kicker is that even when the swell bumps up, the wind ruins it. Take Monday the 7th of September – we’ve got a solid 7ft swell from the W with a 12-second period (combined energy of 1280 – strong), but it’s smashed by a fresh cross-onshore breeze. That’s messy, lumpy, and borderline dangerous for a beach break. Same story on Tuesday the 8th with 8ft from the WNW and 19 mph winds – that’s expert-only territory with the size and chop, and it’s not clean enough to be worth it.
The water temperature sits at 64°, which is about 2° warmer than normal for this time of year – a bit of a mild start to autumn, but it doesn’t make the surf any better.
There’s really no standout session here. The closest thing to a window is the 5th, but even then it’s marginal. Usually, Portreath can bounce back, but this forecast is a long, dry run. If you’ve got a kite, maybe keep an eye on the windier days, but for a paddle surfer, it’s a tough watch.
Stay patient. 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).
Further information to help with frequently asked questions about our surf forecast for Portreath Beach 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.
