The Lowdown
Alright folks, Rusty here. Let’s be honest, we’re looking at a tough stretch ahead. The forecast for Maenporth over the next 16 days is about as flat and uneventful as it gets. There’s a big gap of dud surf right from the start, with nothing worth paddling out for from July 21st all the way through to the end of the month. We’re talking over a week of tiny, weak slop with combined swell energy barely registering (1 to 16), and the occasional 2ft bump that just doesn’t have any push behind it. The water temperature is sitting at 67°, which is much warmer than normal for this time of year.
Now, there is a tiny flicker of hope right at the tail end of the window. Come Sunday, August 2nd, we finally see a pulse of energy. The afternoon session shows a 4ft swell coming from the east, with a period of 7 seconds. The combined energy jumps up to 237 (moderate), and blowin’ moderate offshore from the NNW. That’s a clean look for Maenporth. It’s not a world-beater, but after so many days of nothing, it’s the only real standout. That moderate offshore wind will have the surface glassy. Be aware, with the swell only at 4ft, it’s a fun size for most, not a big-wave day, but after this dry spell, it’ll feel like a gift. The consistency is listed as inconsistent though, so patience will be key.
The following Monday, August 3rd, has a smaller, cleaner 2ft offering in the morning, but that Sunday afternoon is the one to circle on the calendar. The rest of the window fades back into small, choppy, or onshore junk. The water temp anomaly is only given for the first record, so we’re not sure how it holds up later. Get out there on the 2nd if you can.
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.
