The Lowdown
Alright folks, Rusty here. Let’s look at what’s coming down the line for our local patch.
Honestly, it’s a pretty bleak start. We’re looking at a long stretch of flat, tiny, or just plain messy conditions. From now through the end of July, there’s nothing to get excited about at all. The first few days bring nothing but weak, short-period windswell at best, with a lot of onshore or cross-off winds that just aren't cooperating. The water is a balmy 67°, which is much warmer than normal for this time of year, so at least the paddle won’t be cold, but you won’t be catching anything.
The real action, if you can call it that, is a long way off. We’ve got a solid gap of nearly a week with no surf to speak of after that. Then, on the morning of the 1st of August, we finally see a pulse of energy. The combined swell energy jumps to moderate (112) with a 2ft swell from the WSW, but it’s short-period at 10 seconds, and a fresh cross-off wind will keep it clean. By the afternoon of the 1st, the swell builds to a chunky 8ft from the WSW with an 8-second period, and the combined energy goes strong (644). That’s a lot of water moving around, but with that short period, it’s going to be a bit of a washing machine. That’s strictly for the experts, as anything over 8ft is no place for beginners. The wind will be a fresh cross-off, so it’ll be clean, but that’s a beast of a wave for a sheltered spot like Maenporth. The setup looks more interesting for kite surfing than paddle surfing on that afternoon.
After that big pulse, we’re back to flat again through the 2nd and 3rd. The 4th of August shows a tiny glimmer of hope with a 1ft glassy afternoon on the 4th, but it’s barely a ripple. The 5th has a 2ft morning, but it’s short-period and weak.
If I had to pick the one true standout from this whole 16-day window, it’s the afternoon of the 1st of August. It’s the only time we see any significant size, but it’s a beast. The morning of the 1st is the better bet for a more manageable wave, but it’s still not great. Don’t hold your breath for the rest of it.
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.
