The Lowdown
Right then, let’s get this straight from the off. Honestly, the next week and a half is looking pretty flat for us here at Maenporth. The water is much warmer than normal for this time of year, coming in at 67°, which is a nice surprise, but that’s about the only good news. The combined swell energy is barely a whisper, with values like 12 (weak) and even dropping to 1. It’s a tough stretch.
We’re looking at Sunday the 19th of July to start. A tiny 0.3 ft southerly swell with a 19-second period, but it’s just too weak to do anything with. The best you could hope for is a bit of a wobble, but it’s not worth getting wet for.
Monday the 20th is a write-off. A 1 ft easterly windswell with a 3-second period is just mush, and the cross-onshore wind won’t help. Tuesday morning offers a glassy 0.7 ft easterly bump, but it’s flat. The afternoon is glassy again, but still nothing on the face.
Wednesday the 22nd has some clean, cross-offshore winds, but the swell is a pathetic 0.7 ft. It’s a beautiful day to be on the beach, not in the water. Thursday through Saturday stays in the same rut – tiny 0.3 ft swells, mostly from the south-west, with clean conditions but no power. The combined energy is stuck between 4 and 8.
Sunday the 26th afternoon sees a shift to a 0.7 ft SSW swell with a 6-second period and a moderate offshore wind (NW, 12 mph). It’s clean, but it’s still just a ripple. Monday the 27th and Tuesday the 28th are similar stories – clean conditions, small swells, no real punch.
From Wednesday the 29th of July right through to Monday the 3rd of August, the forecast shows zero swell energy. The ocean is going to be flat as a pancake. There’s absolutely nothing to recommend. For a spot that’s already inconsistent, this is a proper blank run. The conditions are clean, but there’s no wave to ride. If you’re desperate, you’re just looking at a saltwater bath.
The only positive is that it’s inconsistent here, so this kind of flat spell is normal. But there’s nothing to surf.

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.
