The Lowdown
Alright folks, Rusty here. Let’s be straight with you: it’s a quiet stretch ahead for Maenporth. The first real sniff of any kind of wave action doesn’t pop up until Wednesday the 12th of August, and even then, it’s not going to set the world on fire. We’re looking at a solid week of flat or near-flat conditions before that, with a couple of tiny pulses that just won't have enough juice.
The only time the ocean shows a bit of life is around Wednesday the 12th and Thursday the 13th. On Wednesday morning, we get a pulse of swell from the WSW pushing about 3 ft with a period of 10 seconds. The combined energy climbs up to a moderate level (209), which is the most we’ll see, but the wind is a cross-onshore from the ENE at 12 mph. That’ll keep things a bit messy. By Wednesday afternoon, the wind eases right back to a light cross-shore, which is a small improvement for an otherwise small wave.
Thursday the 13th morning is your best bet in this whole outlook. The swell ticks up to about 4 ft from the WSW with an 11-second period, giving us moderate energy (358). We get a solid cross-offshore breeze from the north at 12 mph, which will clean things up nicely for the more experienced surfers. This is a bit punchy for beginners at that size. That’s the standout – it’s not epic, but it’s the cleanest, most powerful wave of the whole run.
After that, it’s back to dribble. From Friday the 14th onwards, we’re looking at tiny 0.3 ft to 1 ft swells, mostly from the south with some long-period groundswell (up to 18 seconds), but the energy is weak (single digits to low 20s). The wind often stays light or offshore, so it’ll be clean, but there’s just no wave to ride. There’s a long, quiet gap from the 15th right through to the end of the 16-day window. A couple of glassy moments on the 17th and 18th might tempt you for a longboard paddle, but honestly, it’s a waiting game.
Water temp is sitting at a warm 66°F with an anomaly of 3°F – a touch warmer than usual for this time of year, which is nice for the wait. Maenporth is a sheltered, beginner-friendly spot when it’s working, but it’s also inconsistent, and this forecast shows that. If you’re determined, Thursday the 13th morning is your window. Otherwise, this is a blank run that feels pretty normal for this area when the swell windows close up.

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.
