The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Maenporth. Gotta be straight with you, this one's a bit of a quiet spell. The whole 16-day window is looking pretty slim, and the first real chance of anything worth paddling out for doesn't show up until the very end.
Right off the bat, from today, Wednesday the 19th of August, right through to the end of the month, it's a total write-off. We're talking tiny, knee-high slop at best, with the swell energy barely registering (24 at its best). Even when the wind goes offshore, there's just no power in the water. There's a solid 12-day gap here with no real recommendations to speak of. The water temp is sitting at 66°F, which is a touch warmer than normal for this time of year, but that's small comfort when there's nothing to ride.
We finally get a flicker of life come Tuesday the 1st of September. The morning brings a pulse of swell – 7ft from the WSW – and the wind is looking clean and cross-offshore. The wave energy jumps right up (559), so there's some proper grunt in the water. Now, at that size, it's getting a bit much for the beginners, but for anyone with a bit of experience, this is the standout of the whole outlook. It's a short-period swell at 8 seconds, so it'll be a bit walled up and not the most drawn-out ride, but with clean conditions and some push, it's the best we're gonna get. That afternoon, the swell bumps up to 8ft, but the wind picks up to a fresh 19 mph cross-off, which could make it a bit of a battle.
After that little burst, it all fades away again quickly. By Wednesday the 2nd and Thursday the 3rd of September, we're back to tiny, weak waves and inconsistent energy. The whole period is a bit of a struggle, but that Tuesday morning window is the one to circle if you're keen.
Rusty.

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.
