The Lowdown
Alright folks, Rusty here. Let's be straight with you. I've stared at the charts for Maenporth for the next couple of weeks, and it's a tough watch. We've got a whole lot of nothing on the horizon. This is one of those stretches where the ocean just… forgets to show up.
Honestly, for the next week and a half, you can leave the boards in the van. We're talking about waves that are barely a ripple, with energy readings in the single digits and low teens (4, 7, 6). All coming in at a pathetic 0.3ft. The wind is all over the place, often cross or even onshore, making a mess of an already flat ocean. The only good news is that the winds are light to moderate, so it’ll be pretty, just useless. There are a few moments with cleaner, offshore conditions, but with nothing to push, it doesn't matter. It's a blank run for sure. Don't get your hopes up for the 15th or the 16th; that offshore breeze just doesn't have any swell to groom. This looks like it's going to be a proper dry spell for our little corner of the coast.
The first real hint of life doesn't show up until around the 21st of September. Things start to shift slightly, with a bit more energy in the water, still tiny, but something is happening. The 21st afternoon shows a pulse of 2ft at a super short period of 4 seconds, with the wind easing off. It's not going to be good, but it's something. The 22nd has similar small, short-period waves. But that’s about it. It’s all still "poor surf conditions" according to the forecast, so the hope is pretty faint.
The last day on the charts, the 27th of September, shows a little more energy again (11), but the swell is still just 0.3ft. Still poor. The bottom line is there is simply nothing rideable. There are no standout days here. None. With the water temps around average for this time of year, it's just a waiting game.
It’s one of those times to do a beach clean, tinker with your fins, or go for a run. A stretch like this is more normal for the area than we'd like to admit, but it never stays flat forever. Forecasts can change, and we just have to be ready when the ocean wakes up. Hang in there.

A general guide to surfing at Maenporth can be found by selecting the local surf guide option on the grey menu.

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 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. 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.
