The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a tough one for the local area. We’ve got a long stretch ahead with nothing really worth paddling out for, so don’t go getting your hopes up too early.
The Overall Picture
The first real chance of a wave comes in on Monday the 7th, but it’s a bit of a mess. Before that, the whole weekend is a write-off with tiny bump and no energy. We’re looking at a solid gap of about five days with nothing on the cards. The water is sitting at 64°F at Maenporth, which is a touch warmer than normal for this time of year, but that’s about the only good news.
The Breakdown
Monday 7th September – Afternoon
We finally see a pulse of energy, but it’s not pretty. The swell hits 8ft out of the WSW with a period of 10 seconds. The combined energy is a hefty 1100, so there’s plenty of push, but the wind is a fresh cross-offshore breeze at 19 mph. This is a big, messy, blown-out wave. It’s only for the experienced crew, and honestly, with that wind, it’s going to be a battle. The wave comment says "marginal", and I’d agree. It’s a pass for me.
The Rest of the Run
After that little spike, it’s back to nothing. The following days are flat or showing tiny 0.3ft bumps with no real energy. The 16th of September shows a near-gale offshore wind with a 0.7ft swell – that’s a kite-surfing day, not a surfing one. By the 17th, we get a tiny 4ft easterly windswell, but the period is a miserable 3 seconds, and it’s all chop. No good.
The Verdict
There’s no standout here. The only real pulse on Monday the 7th is too windy and too raw. We’ve got a long, dry spell ahead. It’s one of those quiet periods for the area. Don’t put the board away, but definitely don’t rush to the water. Forecasts can change, but right now, this is a lean run.
Rusty.

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 Maenporth 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.
