The Lowdown
Alright folks, Rusty here. Let’s have a look at what the ocean’s got cookin’ for Maenporth over the next couple of weeks. I’ll be straight with ya – it’s a bit of a rough patch ahead, but there’s a glimmer or two if you know where to look.
Right off the bat, the water’s runnin’ a touch warmer than usual for this time of year, about 4°F above the norm, so you might not need the thickest suit just yet. But don’t get too excited about the waves, because for the next few days, it’s looking pretty grim.
Wednesday and Thursday are basically write-offs. We’ve got some small, weak swell pushing in, but the wind’s all over the shop, putting a chop on it and making things messy. The wave energy is weak, down in the low double digits and just over 200 (111) on Thursday arvo when a slightly bigger but junky 5ft southwest swell shows up with a short, weak 7-second period. Not worth paddling out for.
Now, Friday the 11th is where things get interesting for a minute. The morning looks like the pick of the entire forecast, honestly. We’ve got a clean 5ft swell from the west-southwest with a 9-second period, and a light offshore breeze. The combined energy jumps up to 418, which is a solid, moderate pulse. This is the standout window. It’s still a bit small for Maenporth to be at its absolute best, but conditions should be glassy and clean. The crowd factor could be a thing here as it’s often got company, but for a fun, honest surf, this is your window.
After that Friday morning pulse, it’s like someone pulled the plug. From Saturday the 12th all the way through to the 20th, we’re looking at a proper flat spell. There’s nothing but tiny scraps of energy, mostly under 2ft, with some long-period leftover groundswell that doesn’t have any power behind it. The energy readings are pitiful, often in the single digits. You’ll have clean conditions at times, even glassy on the morning of Monday the 21st, but there just isn’t a wave to ride. This is a solid week and a half of no surf, so don’t hold your breath.
Things start to shuffle back to life around the 21st and 22nd. We see the swell height climb back to 5ft, but it’s coming from the east with a short, weak 6-second period. It’s a bit of a boily, crumbly mess, and the combined energy is only moderate at best (161, 167). These east swells aren’t ideal for Maenporth, which prefers a more southerly direction. While there’s clean, offshore wind on the 22nd, the quality just isn’t there, and the forecast scores reflect that.
So, to wrap it up: there’s really only one true standout in this whole 16-day stretch, and that’s Friday the 11th in the morning. Get out there if you can. Otherwise, it’s a long, flat grind until the very end of the period, and even then it’s looking pretty average. Stay patient.

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.
