The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for our local patch.
Well, I gotta be straight with you – the next week and a half is about as flat as a millpond. We’re looking at a proper drought of swell. From now, right through the end of July, the only thing on offer is tiny dribbles of energy, nothing ridable. The water’s pretty warm though, sitting at 67°F, which is much warmer than usual for this time of year, but that's small comfort when there's no waves.
We finally get a flicker of life on Sunday, August 2nd. The morning sees a weak 4ft swell from the SSW, but with a short, weak period of 5 seconds, the combined energy is only 59 – that's weak. The afternoon is a bit more promising, with the swell building to 5ft from the WSW, with a period of 9 seconds, giving us a moderate 338 combined energy. The wind is offshore from the WNW at 16 mph, which will keep it clean. Still, for a beginner spot like Maenporth, that 5ft might be a bit much, and the quality is still flagged as poor.
Monday, August 3rd keeps the hope alive. The morning has a 4ft WSW swell (7 seconds, 137 energy) with a light offshore breeze from the WNW at 9 mph. The afternoon drops off a bit to 3ft from the SW. It’s more of the same, not really a standout for the experienced surfer, but if you're desperate for a paddle, it's the best we've got. After that, it looks like we fade back into small, onshore junk.
So, if you're pinning your hopes on one day, Sunday, August 2nd afternoon is the pick of a very poor bunch. The offshore wind is a major plus, but the quality is still a question mark. It’s a long way out, so treat it with a pinch of salt. For now, keep the boards in the garage.
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.
