The Lowdown
Alright, I’m Rusty, and I’ve got to be honest with you – the next 16 days at Maenporth are a real bummer. There’s a big, empty gap at the start, and the first chance to even talk about surf comes on Wednesday, July 15th, but it’s a total write-off. We’ve got a 4ft easterly swell, but the wind is a cross-on mess from the east at 15 mph, making it choppy and poor. The combined wave energy is only moderate, sitting around 141-179. It’s not worth your time.
That keeps up all week. Thursday the 16th, the swell drops to 3ft, and while we get a glassy moment in the afternoon, the energy is weak (84-76). The waves are just not there. Friday through the weekend into next week, the swell is tiny, mostly under 2ft, and the energy is pitiful. That period from the 18th to the 24th is a real dead zone; we’re looking at heights under 1ft and energy values of 2, 5, 9 – that’s weak energy, barely a ripple. Some days like the 20th and 22nd offer glassy conditions, but with no real swell, it’s a flat spell.
The next glimpse of any size comes on Monday, July 21st, but the swell is only 3ft at best, and the wind is onshore. By Wednesday, July 22nd, we get a bit of a pulse back to 4ft-5ft from the east, and the afternoon goes glassy, which is a tease. But the combined energy is still only moderate (129-160), and the quality is poor. It’s not what you’re looking for.
After that, the swell is gone again. We get a few clean, offshore days from the 24th onward, but the waves are laughable – 0.3ft, 1ft, 1ft. The energy is all in the single digits or low 30s. It’s a flat, clean lake. For a spot that’s already inconsistent and sheltered, this is a long blank run. The water temp is about average for the time of year, so no surprises there.
The only standout, if you can call it that, is the Thursday morning, July 24th, where we have a 0.3ft swell from the southwest with a 13-second period and glassy conditions. But that’s a long period for a tiny wave, and at Maenporth, a beach-and-reef setup, that long period will just make it break too straight. It’s more of a curiosity than a surf. Honestly, this stretch looks more interesting for a kite surfer than a paddle surfer, given the clean but underpowered conditions.
Hang in there. Forecasts change, and it won’t be this flat forever.

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.
