The Lowdown
Right then, let’s talk about Perranporth.
To be straight with you, the next week or so is pretty grim. There’s swell on the way, but the wind just won’t play ball. We’ve got a solid run of onshore and cross-onshore winds that are going to keep things chopped up and messy. The water’s sitting at about 64°F, which is a touch warmer than usual for this time of year, but that’s the only consolation.
Monday the 14th and Tuesday the 15th are write-offs – cross and onshore winds with that 4ft to 6ft of Westerly windswell just getting hammered flat. The wave energy is moderate, but it’s all poor quality.
Wednesday the 16th sees the swell push up to 6ft from the WNW, with a longer period of 11 seconds. The energy is strong, but that onshore wind from the NW ruins it. The same story continues through to Sunday the 20th – a bumpy, lumpy mess.
Now, there is a glimmer. After a long, poor spell, things clean up nicely on Monday the 21st of September. We get a morning of glassy conditions, zero wind, and a 3ft West swell with a long 13-second period. The energy is moderate. It’s not a big day, but it will be clean and rideable. The afternoon goes glassy too, but the swell drops a touch. It’s the best we’ve got for a while.
Tuesday the 22nd is also worth a look. A light offshore from the SE, clean 4ft West swell at 10 seconds. It’s a decent, small clean window. After that, the size drops away into tiny, weak surf through the rest of the week, with a few more clean windows on the 24th and 25th. Thursday the 24th afternoon brings a very long period 18-second groundswell, only 2ft from the WNW, but with a clean offshore breeze. It’ll be super clean but very small.
The standout here is the Monday the 21st morning. It’s not big, but that glassy, clean 3ft West swell with the long period is the only real clean surf on offer in the whole run. Get on it if you can. The crowds can be an issue at Perranporth sometimes, so a clean Monday morning might be your best bet for a bit of space.

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.
