The Lowdown
Alright folks, Rusty here. Let’s take a look at the surf prospects for Maenporth over the next couple of weeks. Straight up, I gotta be honest with you – it’s a tough run ahead. The first few days are looking pretty grim, with hardly anything worth paddling out for. The water temp is sitting around average for this time of year, so no worries there.
The first real glimmer of hope doesn’t show up until the afternoon of Monday the 31st of August. That’s when we get a moderate offshore wind from the WNW, cleaning up a 7ft swell from the WSW with a period of 10 seconds. The combined energy is moderate at 748, and it’s shaping up to be a decent session. Maenporth is a sheltered spot, so this is a rare standout in a flat outlook. The swell direction is swinging a bit, but the offshore wind should keep things tidy.
Then we hit a dry spell again, with barely any surf through the first week of September. The next bit of hope pops up on Friday the 4th of September, with the morning offering a clean 6ft swell from the WSW, period of 8 seconds, and light offshore winds from the WNW. The combined energy is moderate at 452. It’s not massive, but it’s clean and rideable. The afternoon sees a slight bump to 6ft but the wind picks up a bit, making it more marginal.
After that, it’s back to tiny waves and messy conditions for the rest of the run. Saturday the 5th of September afternoon has a 7ft WSW swell with a 10-second period, but the wind is a cross-off, and the combined energy jumps to 729 – moderate – but the overall conditions are still rated poor. Honestly, the best bet is to keep an eye on that Monday the 31st of August afternoon and the Friday the 4th of September morning. The rest of the period is a washout.
Stay patient, lads. Rusty out.

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.
