The Lowdown
Alright folks, Rusty here. I’ve had a look at the books for the coming weeks, and I’ve got to be straight with you – it’s a bit of a slow start before things potentially get interesting.
Right now, and for the next couple of weeks, Maenporth is looking pretty flat. We’re looking at a long stretch of small, weak energy and nothing really worth getting wet for. The combined swell energy is well under 100 for most of it, with a lot of zeros. There’s a gap from now pretty much all the way through the first half of the month where there’s just no proper surf on offer. You’d be chasing shadows.
Around the end of next week, things look like they might kick off. On Friday the 25th of September, we finally see some proper size roll in. The morning shows a 8ft swell from the WSW with a combined energy of 537 (moderate), but the wind is cross-onshore from the East at just 6 mph. That’s a bit of a bummer for conditions, but the size is there. By the afternoon, the swell jumps to a solid 10ft from the same direction, with the combined energy hitting 1744. That’s a strong pulse. For reference, that’s over 8ft, so it’s getting into expert-only territory. The period is 10 seconds, so it’s got some push but not that long, drawn-out groundswell feel. That kind of size here could be more of a kite-surfing setup than a comfortable paddle session given the onshore wind direction.
Looking at the water, it’s about average for the time of year here at Maenporth, so no surprises there. The spot itself is sheltered and inconsistent, meaning it needs a decent push to get going. This particular pulse might just be too messy with that wind to be the standout we’re all hoping for, but it’s definitely the most energetic reading in the whole 16-day window.
Stick with it. It won't be flat forever.
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.
