The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for our local patch. I’ll be straight with you – the next couple of weeks are looking pretty bleak for a proper paddle. We’ve got a long dry spell on the cards before anything half-decent shows its face.
Right now, and for the next week, it’s a write-off. The surf is small, messy, and the wind is sloppy. We’ve got a few pulses of swell, like a 5 ft on Thursday 3rd September morning, but the wind is cross-off and the energy is weak. The water is a touch warmer than normal at 65°, but that’s where the good news ends. Honestly, the conditions are so poor for a surfboard, you might as well be looking at the kiteboarders if the wind picks up.
We’re looking at a gap of about 10 days with nothing worth mentioning. The 7th of September Monday afternoon sees a little pulse of 3 ft swell from the WSW, but it’s just not enough to get excited about. The whole first week is a write-off for any decent waves.
The only real standout, and I’m using the term loosely, comes on the 13th and 14th of September. We’ve got a building swell from the east, pushing 6 ft to 8 ft, with a short period of 6 to 7 seconds. The combined energy is moderate to strong (273 to 542), but it’s a straight onshore wind from the east, making it choppy and bumpy. That’s not a classic surf setup; it’s more of a messy, fat wave. The swell size is big enough for experienced surfers only, but the quality is poor. This is the kind of window where you might get a few fast, crumbly walls at Maenporth if you’re desperate, but the wind is killing it. This is a “leave your board in the car and watch” kind of period.
The even later period, after the 14th, is almost non-existent. The swell drops off to nothing. Honestly, it’s a tough outlook. The setup looks more interesting for a kite than a paddle. Don’t book the time off work just yet. Keep an eye on the charts, but for now, it’s a no-go.
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.
