The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.
First off, I gotta be straight with you – it’s a flat spell for Maenporth for a long stretch. We’re looking at a good week and a half of nothing worth paddling out for. The water is running at 66.7° which is much warmer than normal for this time of year, a real anomaly of 5° above average, so it’s a beautiful temperature for a swim, but not for a surf.
The first few days, from Monday the 20th right through to Sunday the 26th, are just a write-off. We’re talking tiny dribbles of swell, all under 1ft, with weak energy readings mostly in the single digits (2). The swell periods are short and gutless, mostly 3 to 4 seconds. The wind is all over the place, sometimes glassy, sometimes cross-off, but it doesn’t matter because there’s nothing to ride.
Things stay small and inconsistent through the next week. Monday the 27th through to Thursday the 30th, the swell is still just 0.3ft, with a few longer period signals, but they are barely registering any energy. The wind is mostly offshore or cross-off, but the sea is dead flat. You’ll get some clean, glassy conditions, but with zero wave height.
Finally, we get a tiny flicker of life on Saturday the 1st of August. The afternoon shows a 1.6ft swell from the east, with a period of 4 seconds and a combined energy of 11 (moderate breeze, offshore). It’s a weak, short-period windswell, but it’s the first pulse we’ve had. The best of the bunch is the following morning, on Sunday the 2nd of August. The morning session is glassy with a light WNW breeze, 1ft of east swell, period 6 seconds, and energy of 6. It’s tiny, clean, and the water is likely still warm, so it’s a beginner-friendly option if you’re desperate for a splash. The break is inconsistent, and it’s a sheltered spot, so it takes a lot to get it going. On the plus side, it is often crowded, but with these tiny waves, it might be pretty quiet.
After that, it’s back to flatness on Monday the 3rd and Tuesday the 4th. The only real standout, if you can call it that, is the Sunday morning session on the 2nd of August. It’s the cleanest, most glassy, and has the most promise out of the whole 16 days, but it’s still a very small wave. For a proper surf, you’ll have to wait for a better swell.

Information about the Maenporth Surf forecast
The above surf forecast table for Maenporth provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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.
