The Lowdown
Alright, folks, Rusty here. Let’s be straight with you: this is a grim one for the foreseeable future. We’re looking at a 16-day stretch starting now, and the honest truth is there’s nothing worth paddling out for. The first week is a total washout, and the second week doesn’t improve. We’re talking day after day of flat, tiny, or messy junk.
The only spot on the radar is Maenporth. It’s a beginner-friendly, sheltered little cove that usually needs a decent push from the SSE to get going. Problem is, the swell just isn’t there. The water is sitting at 66°F which is a touch warmer than normal for this time of year, but that’s about the only comfort.
For the first few days, from Friday 7th August through to Monday 10th, we’ve got absolutely nothing. Swell heights are 0.3ft to 1ft with periods all over the shop. The best wind we see is a glassy moment on Monday afternoon (10th August) with a NNW breeze at 3 mph, but even then, the combined energy is only 16 – that’s weak, barely a ripple. It’s not surf.
Things try to pretend to get interesting mid-week. On Tuesday 11th, the swell bumps up to 3ft to 5ft from the ESE, but the wind is howling onshore at 19 to 22 mph – that’s a fresh cross-onshore, making it choppy and lumpy. Even with the energy jumping to moderate levels ( 123 ), it’s a mess. By Wednesday 12th, the swell is coming from the E with a period of 7 seconds – short period, weak, and the wind is still honking onshore. The energy hits 303 that morning, but trust me, it’s not the kind of wave you want.
Towards the end of the first week, Thursday 13th gives us a brief window of clean, offshore wind from the NW at 9 to 12 mph and a 3ft swell from the WSW with a 9-second period. The energy is 154 – moderate. This is the closest we get to a surfable day, but the swell is still small and inconsistent. It’s a thought, not a session.
Then from Friday 14th all the way through to Saturday 22nd August, we drop right back to tiny, 0.3ft to 0.7ft slop, with long-period groundswell (15-17 seconds) but zero push. The energy values are all in the single digits, up to 29 at best. The wind is a mix of cross-offshore and cross-onshore, but it doesn’t matter because there’s no wave to ride.
There is no standout. There is no best option. We’ve got a long, blank run here. For a sheltered spot like Maenporth, this kind of dead spell is more normal than you’d hope. The forecasts can change, but right now, I’d save the petrol and wax.
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.
