The Lowdown
Alright, folks, Rusty here. Let’s have a good look at what Maenporth is serving up over the next couple of weeks.
Right off the bat, I gotta be straight with you – the next week and a bit is looking pretty grim. There’s a real dry spell for quality waves. We’ve got a long stretch of poor surf conditions from now until the end of August and into the very start of September. The onshore winds are going to be messing things up, with cross-on breezes and choppy seas. The swell is there, but it’s small and messy, or it’s blown out. Don’t bother waxing up for that.
The first real glimmer of hope shows up on Tuesday, 1st of September. Now, we’re looking at a clean morning with offshore winds, but it’s a tricky one. The swell is pumping up to 8 ft from the WSW with a 9-second period, and the energy is strong (1057). Because it’s pushing past 8 ft, this one is strictly for the experts. Beginners, give this a miss. The conditions are described as marginal, with questionable tide, so it’s not a no-brainer, but it’s the first real size we’ve seen. The afternoon gets even bigger – 12 ft – but the wind picks up to a fresh breeze, so it’s going to be a battle.
The pattern then gets messy again with cross-shore winds for a couple of days. The real standout, and the one I’d circle on your calendar, is Saturday, 5th of September. We’ve got a solid 10 ft swell from the WSW carrying a lot of energy (1220-1342). The wind is offshore and clean, which is a beautiful combination. At this size, it’s big, powerful stuff – definitely expert territory again, but the potential for some epic, clean waves at Maenporth if you can handle it. It’s a long-range call, so it’s promising, but don’t book the day off just yet.
Looking further out, Wednesday, 9th of September also shows a big 10 ft swell from the WSW with a very long period of 11 seconds. That kind of period means really clean, powerful groundswell. Given Maenporth is a sheltered spot (optimum from SSE), this WSW direction might not hit it perfectly, but a clean 10 ft is hard to ignore. The wind is offshore and light. Again, it’s a long way off, but it’s the best looking day on paper by a long shot.
So, to sum it up: a whole lot of nothing for the first week, then some big, expert-only swell potentially kicking off from the 1st of September. The standout is the 9th of September for that combination of clean, offshore wind and a long-period groundswell. Keep your ear to the ground on that one.
The water is currently sitting at a touch warmer than normal for the time of year, about 65°, so the rubber isn’t a must yet.

Information about the Maenporth Surf forecast
The above surf forecast table for Maenporth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Maenporth can be found by selecting the local surf guide option on the grey menu. Our Maenporth surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Maenporth) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
