The Lowdown
Alright folks, Rusty here. Let's have a look at what the next couple of weeks are serving up for us.
Well, I've gotta be straight with you – this is a tough one. Looking at the whole 16-day run, there's just no surf on offer that's worth getting excited about. The first time we see any wave energy pop up is on the 8th of August, and even then, it’s tiny, weak, and messy. We're looking at a long, dry spell with barely a ripple.
The only break in the mix is Maenporth, and it's a sheltered, beginner-friendly spot that's pretty inconsistent at the best of times. The water temp is sitting at 66°F, which is a touch warmer than normal for this time of year, but that's about the only positive.
For the first week, from the 8th to the 15th of August, it’s just non-stop poor surf. Tiny swells from the east and south, nothing over 3ft, and periods are mostly short and weak. The combined energy is barely registering, with values like 14, 5, and 48 – all weak. The winds are all over the place, from cross-on to offshore, but with waves this small, it doesn't matter. You'd be bobbing around on a lake.
There’s a little bump in energy on the 12th of August, with a combined energy reading of 199 (moderate), but the swell is still under 3ft and the wind is a cross-onshore. It’s still not rideable.
The second week doesn’t offer much hope either. We see a bit of a spike on the 19th of August with a 5ft swell from the WSW, giving a combined energy of 250 (moderate). That’s the biggest of the whole run. But here's the thing – the period is only 7 seconds, so it's just weak, wind-affected chop. The wind is offshore from the NW, which is clean, but the quality of the swell is so poor, it's still a write-off.
Honestly, for most of this period, with the small, weak swell and the onshore/cross-shore winds, this setup looks more interesting for a kite surfer than a paddle surfer. If you've got a kite, you might get some fun on those windier days, but for a surfboard, you're better off waiting.
Forecasts can change, but right now, it's a blank run. It's one of those stretches where Maenporth just doesn't fire.
Stay patient,
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.
