The Lowdown
Alright, Rusty here again, same story but in old-school numbers. Let's have a look down at Maenporth.
It's a tough outlook, I won't lie. We've got a 16-day window and, honest to God, there's hardly a wave worth talking about until next Monday.
The water's hanging around 18°, which feels a touch warmer than normal for the season, but that's the only thing that isn't a letdown.
For the first few days, through Friday, Saturday, and Sunday, we're seeing tiny, flat waves. Swells are just 0.7ft to 3ft, with periods so short there's no push. The combined energy is pathetic, topping out at 37 (weak). Friday afternoon and Saturday morning are glassy, but there's nothing to surf. Maenporth is a sheltered beginner spot, and it's just not working. Expect a long, flat stretch.
Things finally *try* to happen on Monday the 7th of September. We get a jump in swell to about 7ft out of the WSW, with a 13-second period. That's a moderate groundswell, and the combined energy jumps up to 1555 (very strong). This is the only event in the whole 16-day window worth mentioning. But that's a lot of power for a sheltered beginner break—7ft is pushing past beginner territory. The morning wind is a moderate cross-off, so it should be clean. Keep in mind, the crowds can be *often* here, so expect some company for what's likely a lumpy, powerful wave.
By Monday afternoon, the swell drops to 7ft (moderate energy at 1059), and the wind stays clean. This is the one moment to circle on your calendar.
After that Monday pulse, it's back to the desert. From Tuesday the 8th through to the 19th on Saturday, it's a whole lot of nothing. Swell heights are down to 0.3ft or flat, with the odd clean wind but no waves. There's a bit of northerly wind later, but that just dries out the flatness.
Look, if you're a beginner and Monday feels manageable, you could get a couple of clean ones. But for most of us, this is a 16-day blank. For a spot like Maenporth, a run this poor isn't unusual when we're stuck between swells. The forecasts can change, but right now, there's just one day to keep an eye on.
Keep your head up, 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.
