The Lowdown

Alright folks, Rusty here. Let's have a look at what Maenporth has in store for us. I gotta be straight with you – this is a tough one. We're looking at a pretty desperate run for most of the next two weeks. There's a tiny window where things get interesting, but you'll need patience and low expectations.

Right now and for the vast majority of the forecast, we're staring down the barrel of almost nothing. From August 14th right through to the 23rd, it's a long, flat spell. We're talking swell heights barely scraping 0.7 ft, with a combined energy that's mostly just single or low double digits (7 to 48). That's weak sauce, plain and simple. The wind is often offshore or cross-offshore, which would be fantastic if there was any wave to blow on, but there isn't. Maenporth is a sheltered spot and needs something from the SSE to really light up, and we're just not getting that. It's going to be a glassy, clean lake out there for over a week.

Now, here's where it gets a little spicy. On Monday the 24th of August, something finally changes. The morning shows a pulse of swell coming in at 4 ft from the East, but with a super short period of 5 seconds. By the afternoon, it builds to 5 ft from the East, with the period still a weak 7 seconds. The combined energy jumps up significantly – we're talking 349 in the afternoon (moderate wave energy). The wind is offshore from the NW. This is the only real surfable window in the whole 16 days. However, the conditions are described as "very ordinary."

This is a tricky one. That 5 ft East swell with a short period is going to be a bit of a mess. It's not going to have that long-period groundswell power. Because the period is under 8 seconds, it's going to be weaker and more crumbly. For a sheltered spot like Maenporth, it might just be enough for a fun little session on a longboard, but don't expect any barrels. It's a one-day wonder then it drops back to nothing. It’s the best on offer, and it’s a consolation prize.

After that, it's back to the doldrums. Tuesday the 25th is small again, and by Wednesday the 26th, the wind swings onshore, killing any hope. There's a brief blip on Thursday the 27th with some 4 ft swell from the WSW, but the wind is onshore from the SE, making it messy and blown out. Not worth the paddle out.

So, to sum it up: do not rush down there now. You've got a solid 10 days of flatness. The only real chance is Monday the 24th of August. It’s not going to be epic, but if you’re desperate for a paddle, that’s your window. The rest of the time, leave your board at home.

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.

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.
