The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Maenporth over the next couple weeks.
Well, I gotta be straight with you – this is a tough run. We’re lookin’ at a long, drawn-out stretch of flat, small, or just plain messy conditions. The first real chance of anything rideable doesn't show up until the very tail end of the forecast, around the 17th and 18th of August. Before that, you’re lookin’ at well over a week of nothing to get excited about. The early days have a bit of waist-high stuff around the 3rd and 4th, but it’s all cross-shore and choppy, with the swell energy sittin’ weak to moderate (104 to 243), and a short, weak period of 7 to 8 seconds. Not worth paddlin’ out for.
The real highlight, and I mean *the only* highlight, is nudgin’ into the second week. On Monday the 17th of August, the afternoon looks like our best shot at something. We’ve got the wind swingin’ offshore from the northwest at a clean 15 mph, which is a major positive for a sheltered little spot like Maenporth. The swell starts to show some life, pushin’ to 4 ft from the ESE with a short period of 5 seconds, and the combined energy jumps up to 75 – still low, but it’s somethin’. The water temp is about average for the time of year, so no major surprises there.
Then, Tuesday the 18th of August morning is where your ears should perk up. We’re seein’ a 5 ft swell from the east with moderate offshore wind from the northwest at 12 mph. The combined swell energy ticks up into moderate territory at 126. This is the best on offer, no doubt. The waves will have a bit more push, and with the offshore wind, it should be clean. It’s still a short-period swell though, so don't expect it to be lined up perfectly. Maenporth can get a bit inconsistent, so patience will be key, and it’s a spot where you might see a few others in the water.
For the rest of the run? A lot of clean-looking mornings with flat surf or tiny dribblers. It’s not great for paddle surfing, and honestly, with the stronger onshores and lumpy water we see earlier on, this setup looks more interesting for kite surfing than anything else. Don’t get your hopes up for the first week; it’s a proper blank run.
Stay patient. Forecasts can change. Rusty out.

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.
