The Lowdown
Alright, surfers, it’s Rusty here, and I’ve got the lowdown on the next stretch of waves for Perranporth.
Right off the bat, I'm not gonna lie to you—this forecast is a bit of a famine. We've got a long, dusty stretch of onshore junk and weak, crumbly swell ahead. The first week is pretty much a write-off. The water is sitting at 66°, which is a touch warmer than normal for this time of year, but that’s about the only buzz out there. The swell energy is weak, mostly in the double digits, and there’s the occasional moderate pulse, like on the 20th with 349 energy, but it's all getting chopped up by persistent onshore winds. It’s going to be lumpy, messy, and pretty much a struggle if you’re not a masochist.
There is a gap of a few days where you’ll just want to stay on the beach. The first glimmer of hope comes on the morning of Friday, the 21st. We've got a small, 3ft west swell rolling in with a period of 8 seconds, and the wind goes glassy. That’s our first real window. The energy is only moderate at 158, but clean, small waves are better than no waves. The break is fairly consistent, so there should be a few to pick from, but expect it to be small and soft. Crowds are possible on a clean day like this.
The following week is still pretty inconsistent. There’s a tease of offshore winds on the 22nd, but the swell drops out, and there’s a long stretch until the 27th where it's tiny and clean but essentially flat. The standout, if you can call it that, looks to be the afternoon of Thursday, the 27th. We get another 2ft west swell, but this time the period bumps up to 10 seconds, the wind goes glassy again, and the energy is a bit better at 94. It’s still very clean and small, but it might be the most lined-up the place gets for a week and a half. It’ll be one for the longboard, for sure, and you might have it a bit more to yourself, especially with that inconsistent nature showing up. The morning of the 28th also looks clean with a light offshore breeze and a similar, weak 2ft swell. Beyond that, there’s not much else. The models hint at a little more energy on the 29th, but it’s a promise for later, not a guarantee for now.
Stay keen.
Rusty.

Information about the Perranporth Surf forecast
The above surf forecast table for Perranporth provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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.
