The Lowdown
Alright folks, Rusty here. Let’s chew through the next couple of weeks for Maenporth. I’ll be honest, it’s a dry spell for the most part, with a lot of flat days to get through.
The 16-day run starts with barely a ripple. The first sign of any real action doesn’t show up until the afternoon of August 16th, so you’re looking at a solid 12-day gap with nothing worth paddling out for. The early part of the window is just a series of tiny, wobbly lines with poor surf conditions – cross-shore breezes, lumpy chop, and a lot of frustration. The water is a touch warmer than normal for this time of year at 66°, but that’s about the only thing going for it.
The one true standout, and the only time you should seriously consider a session, is the weekend of August 17th. The surf kicks in from the afternoon of Sunday the 16th, with a building 7ft swell from the southwest, and the combined energy jumps to 412 (moderate). That’s moderate wave energy, but it’s the first real pulse we’ve seen. The wind is offshore from the WNW at 16 mph, so that’s a major positive – it’ll keep the faces clean.
That swell carries into Monday August 17th. Morning sees a solid 7ft WSW swell, with a moderate offshore breeze from the WNW at 12 mph. The combined energy is up to 470 (moderate). The afternoon gets a bit choppier with a cross-off wind, but the swell is still a healthy 7ft. This is the best bet for the whole forecast. At 7ft to 7ft, this is expert territory – too big for beginners, and it’s going to pack a punch. The period is only 7-8 seconds, so it’s a windswell, not a long groundswell, meaning it’ll be a bit more crumbly and less consistent between sets. It’s a beach break, so with that size and a short period, expect some fun, punchy walls but also a bit of a washing machine. The crowd factor here is “often”, so be prepared for company.
After that, the energy drops off a cliff again. Tuesday the 18th gets nuked by strong offshore winds (25 mph) that are hard to paddle into, and the swell is gone. The rest of the window is back to junk.
So, to sum it up: don’t bother until the 16th. The 17th is the hero day – a solid, clean, expert-level swell with offshore wind. Get on it, because it’s all we’ve got.
Rusty.

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.
