The Lowdown
Alright, mate, Rusty here. Let's have a look at what's on the cards for our local patch.
Honestly, the next couple of weeks look pretty grim. We're in for a long, quiet spell with barely anything worth paddling out for. The whole 16-day window is a bit of a write-off, with no proper surf on offer. The first real action doesn't even show up on the charts until the end of the first week, and even then, it's a struggle.
The first surfable day looks to be Monday, the 31st of August, but even that's a marginal call. The water temp is sitting at 65°, which is a touch warmer than usual for this time of year, so at least you won't be freezing your toes off waiting for a set. But that's about the only positive.
Let's break it down. The best of a bad bunch is Maenporth, but it's a real "beggars can't be choosers" situation. For a standout, I'd have to point to Friday, the 4th of September, in the morning. We'll see a 8ft swell from the WSW with a moderate wave energy (706), and a clean, cross-off wind from the W at 19 mph. The waves will be a bit fat and short-period, but it's the cleanest we'll get. That said, this spot is inconsistent and sheltered, so don't expect a classic.
Another one to keep an eye on is Thursday, the 10th of September, in the morning. There's a bigger 8ft swell from the WSW with a very strong wave energy (1485), and a period of 11 seconds, so it's a proper groundswell. The wind is cross-shore from the ENE at 12 mph, which will leave it a bit bumpy. This is a big one, over 8ft, so it's for experienced surfers only. The afternoon looks even bigger at 10ft, but it's a bit blown out.
For the rest of the time, it's a dead loss. There are large gaps of days with no recommendations at all. The setup is just too small, too windy, or too messy for any decent paddle surfing. Honestly, with the strong winds and big, messy swell we see on a few days, this setup might be more interesting for kite surfing than pulling on a wetsuit.
So, there you have it. A long, quiet stretch ahead. The forecasts can change, so keep an eye on it, but for now, don't hold your breath. Keep the boards waxed and wait for the next one.
Rusty.

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.
