The Lowdown
Alright, Rusty here again. Let’s break down the surf in feet and Fahrenheit.
Honestly, it’s a rough go of it for the next couple of weeks. We’re looking at a big, long flat spell right from the start. From now through about the 7th of August, there’s hardly anything to ride. Most days are showing tiny, weak waves or just flat calm. The energy numbers are all in the single digits and low hundreds. It’s a proper drought.
The only tiny blip in that first week is on the morning of Monday the 4th of August. Maenporth might see a little 4ft swell from the WSW, but it’s a short period of 8 seconds, so it’ll be weak and lacking any push. The combined energy is only 185. The wind is cross-offshore, so it’ll be clean, but it’s just a small, weak wave for the dedicated.
You gotta wait all the way until Saturday the 8th of August for the best wave of the outlook. The morning of the 8th is the one to circle. Maenporth gets a small 4ft of swell from the SW, with a combined energy of 112. It’s not big, but the wind is glassy, dead calm. That’s a huge win. The water is about 36°F warmer than usual, so it’s feeling like a warm bath. The period is 7 seconds, so it’s short period windswell, but on a glassy day, it’ll be the cleanest wave you’ll see all fortnight.
After that, the energy fades again. The 12th and 13th of August show a little more consistency with waist-high stuff from the WSW, but the winds get messy with cross-shore breezes and even a risk of thunderstorms on the 13th. The last few days, the 14th and 15th, are back to tiny, weak waves with fresh, strong winds. Not worth the paddle.
So, bottom line: the one true standout is Saturday morning, the 8th of August. That’s your day. The rest of the 16 days is a flat, windy mess. Maenporth is a sheltered, inconsistent spot, so a blank run like this isn’t out of the ordinary.
Rusty, out.

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.
