The Lowdown
Alright, let’s talk turkey. It’s been a flat, frustrating stretch out there, and we’ve got a long wait before anything real shows up.
The next week and a half is a total write-off. We’re talking ankle-biters and knee-high slop, mostly around 0.1m (that’s less than half a foot), with the combined energy readings stuck in the weak zone – single digits and low teens. The wind’s been a mixed bag, some offshore kicks, some cross-off, but it doesn’t matter when there’s no swell. It’s clean, but flat. Completely flat.
We’re looking at a solid gap from the 15th through the 24th with absolutely nothing. There’s a day or two in there with glassy conditions, like the 23rd when the wind is calm, but the swell is still zero. Pretty to look at, but no surf.
Then things start to change on the 24th. A little Southeast bump shows up, 0.7m to 0.8m (around 3 feet), but the period is a horrible 4-5 seconds. That’s just wind-slop, and with an onshore Easterly breeze, it’ll be lumpy and messy. Not worth the drive. The energy gets a little more noticeable (18, 22, 41), but it’s all short-period junk.
The one true standout – and I mean the only one – is Sunday the 27th. We’ve got a solid WSW swell, 3.5m (over 11 feet) in the morning, easing to 3.0m (10 feet) by the afternoon. Period is 10-11 seconds, so there’s real power. The energy readings jump right up to 2477 and 2388 – the first time we’ve seen anything proper. The catch? The wind is straight onshore from the Southeast. It’s going to be bumpy and raw, and for a sheltered spot like Maenporth (Cornwall), that’s a challenge. This is big – well over 2.5m – so it’s strictly expert-only. Beginners should stay well away.
The morning after, Monday the 28th, looks like the better bet for a session. Swell drops to 2.2m (7 feet), period backs off to 8 seconds, but the wind swings to a light cross-off from the North, which will clean it up. Energy is still solid at 744. It’s still powerful, but with the lighter wind, it’s a much more user-friendly option for experienced surfers. The shorter period might make it a little lumpy, but it’s the pick of the run.
Tuesday the 29th is still rideable – 1.6m (5 feet) with a 9-second period – but a fresh cross-off at 30 km/h will keep it textured. It’s on the way down, and the forecast confidence that far out isn’t great, so don’t plan around it.
Bottom line: over a week of nothing, then one big, messy, expert-only day on the 27th, and a slightly cleaner, still powerful option on the 28th. If you’ve got the skills, keep an eye on the 28th. Otherwise, this is a long, flat stretch.
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.
