The Lowdown
Alright folks, Rusty here. Let’s be straight with you: the next 16 days are a real struggle for Maenporth. The forecast shows a long stretch of flat to tiny, weak, and messy conditions, so don’t get your hopes up for anything decent.
The first real flurry of activity doesn’t arrive until Wednesday 12th August. Through the afternoon, a moderate energy swell (230) shows up from the WSW at 4 ft with a period of 9 seconds. The wind is clean and cross-offshore, so the surface will look tidy. It’s a small step up, but still not firing. Thursday 13th August morning is the pick of the whole run. The morning is glassy—dead calm—with a clean 4 ft swell from the WSW and a slightly longer period of 10 seconds. The combined energy is moderate (251). It’s the most surfable moment of the fortnight, but it’s still small, and the spot is inconsistent and sheltered, so don’t expect much. Crowds are often around here, so you’ll have company trying to pick off those weak little waves.
After that, the weekend of 15th-16th August sees a pulse of 4 ft to 4 ft WSW swell (195-229 energy), but the wind turns cross-onshore and then choppy on the Sunday afternoon, killing the quality. Through the following week, it’s back to flat, tiny dribble with long-period 16-second leftovers that won’t even wrap in properly. This spot just doesn’t have the exposure to make anything of this.
Honestly, there’s no standout session here. The Thursday 13th morning is your best bet, but it’s a desperate call. The water temp is about average for the time of year, nothing unusual. Keep your board waxed and hope the forecasts shift.
Rusty.

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.
