The Lowdown
Right, let’s get into it. This is the outlook for Perranporth.
The whole 16-day window is a bit of a mixed bag. We’re looking at small surf and tricky winds for a good stretch, but there’s a late punch of very significant, powerful swell to keep an eye on, though it won’t come clean. The first real chance to get a wet suit on is on Tuesday morning, 25th August. The swell is small at 2ft from the W, and the period is a bit short at 10 seconds. The wind is offshore from the E at 12 mph though, and combined wave energy is weak (63). You’ll get clean little waves, but it’s very ordinary. That continues into the afternoon.
Wednesday, 26th August, is pretty poor. The wind goes cross and the wave quality drops out. Thursday, 27th August morning offers a slight improvement with a touch more size at 3ft from the SW and light cross-offshore winds. It’s still nothing special though.
Friday, 28th August morning is probably the pick of the first week. A clean 3ft of SW swell with light offshore wind from the ESE (6 mph) and moderate wave energy (130). It’s small but clean, and the light airs will make it a nice morning for a longboard.
From there, it gets rough. Strong onshore winds and lumpy conditions take over through the weekend and into the following week. The swell does build – on Sunday, 30th August afternoon there is 5ft but it’s crossed up with a strong onshore breeze.
Now, the real standout energy arrives towards the end of the window, but you won’t want to paddle out. On Monday, 7th September, there is a massive, very long-period groundswell from the W at 17 seconds, pumping in at 15ft. The combined wave energy is extreme (10556). The wind is onshore from the WNW at 16 mph. That is a huge, powerful ocean, and with onshore wind, it will be a chaotic, dangerous mess for paddle surfing. For anyone without a boat or a foil, this setup looks more interesting for kite surfing than paddle surfing. It’s expert territory, but the conditions won’t be good.
Wednesday, 3rd September and Thursday, 4th September also have some moderate sized west swell, but with cross-shore and onshore winds respectively, the quality will be poor. The entire period is basically a write-off for quality surf. There are no standout days where everything lines up.

A general guide to surfing at Perranporth can be found by selecting the local surf guide option on the grey menu. Our Perranporth 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 (Perranporth) 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 Perranporth 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.
