Right, so here’s the deal for Maenporth in feet and old money. You’re looking at a whole lot of nothing for the next sixteen days.
It starts off totally flat on Saturday. We’re talking a 0.3ft south swell with a 16-second period – sounds fancy but it’s not even a ripple. The combined energy is 5, which is nothing. WNW wind at 13 mph offshore, so the water is clean, but there’s nothing to ride. Sunday and Monday are the same story. A tiny 0.3ft south swell, glassy conditions on Monday morning – beautiful water, flat as a pancake. Water temp is 63°, a touch warmer than usual for this time of year.
Tuesday stays flat at 0.3ft from the southwest, combined energy 6. Wednesday we get a pathetic 1ft east windswell with a 4-second period and a light cross-onshore east breeze. Just a bumpy mess. Thursday and Friday keep that 0.3ft stuff going.
Finally, on Saturday, July 11th, things change a little. The afternoon brings a 4ft east windswell, 6-second period, with a cross-offshore wind from the NNW at 16 mph. Combined energy hits 91, which is still weak. The surface will be clean but the waves will be gutless and closey.
Sunday, July 12th is the only size event. The afternoon hits 6ft from the east, period still 6 seconds, combined energy up to 305 (moderate). But the wind is a light cross-onshore from the east at 6 mph. That’s the wrong direction for Maenporth. Too big, wrong wind, wrong swell direction – better for kite surfing than a paddle board.
Monday keeps that 6ft but wind gets worse. Tuesday afternoon goes glassy with a 5ft east swell, combined energy 182, but the swell direction is still off. It’ll be clean water but the waves will be lumpy.
The most promising days come Thursday, July 16th and Friday, July 17th. Thursday morning has a 4ft SSW swell with offshore NW wind at 16 mph, combined energy 131. That’s a much better swell direction for this spot. Friday morning bottoms out at 5ft from the SW, offshore cross-off wind, combined energy 234. That’s your best bet.
Even then, Maenporth is an inconsistent spot that rarely fires. This whole run is a dud for real surfing. The best you can hope for is a few clean lines on the 16th and 17th if the swell angle holds.

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.
