The Lowdown
Alright, Rusty here. Let’s break down the surf situation at Maenporth.
Truth be told, this outlook is a bummer. There’s a long stretch of real flatness and not much to get stoked about. For most of the 16 days, you’ll be lookin’ at a dry board.
The one window that might get your heart pumpin’ is Saturday, August 29th, in the afternoon. That's the standout, but it's a heavy one. We’re lookin’ at a solid 13ft swell from the WSW, with a period around 10 seconds. The wave energy is through the roof at 2806 (very strong). That is strictly for the pros. The wind is cross-off from the west at 28 mph, so the face will be clean, but it’ll be a battle. Expect some big, heavy sets.
Before that, Friday the 28th is a no-go with 3ft of weak, junk windswell and gusty cross-off winds. Saturday morning, the 29th, shows 8ft but it’s totally wrecked by a near gale. Sunday the 30th is poor with lumpy conditions. Then from Monday, August 31st, right through to Saturday, September 12th, it’s almost completely flat. We’re talking tiny ankle-snappers at best, with groundswell from the south showing up, but no power behind it. Winds are often clean, but there’s nothin’ to ride.
On Saturday, September 12th, there is a tiny 1ft groundswell from the WSW with a long 11-second period. A light offshore breeze from the NW at 9 mph would make it glassy, but you’d be huntin’ for a ripple.
So, for the big-wave chargers, the 29th afternoon might be the call, but it’s heavy. Everyone else is lookin’ at a long pause. Water temp is pretty average for this time of year. It’s a rough outlook, but the forecast can always shift.
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.
