The Lowdown
Alright, grab a coffee and listen up. The first eight or nine days of this forecast are mostly a write-off. We’re lookin’ at a lot of lumpy, onshore mess with some thunderstorm risks thrown in. The water is 65°F, which is a touch warmer than normal for the season, so that’s a small comfort.
The first real glimmer of hope comes on Monday, the 7th of September. The wind goes offshore out of the southeast at just 3 mph, and we’ve got a 6ft swell from the west, with a 11-second period. That’s a groundswell, and the energy’s moderate. It’s gonna be clean. Not huge, but it’s the first clean day in a week. Tuesday morning stays clean with offshore wind, but the swell drops to 4ft – still a fun little session.
The big show starts on Thursday, the 10th of September. The morning has a 8ft swell from the west-southwest, period only 8 seconds, but the wind is offshore from the southeast at 12 mph. The wave comment says expect very good conditions. The afternoon blows up to 8ft from the west, period 9 seconds, with a cross-offshore wind. That’s a powerful, heavy wave. It’s for experienced surfers only.
But the absolute standout is Friday, the 11th of September. The morning is a dream: 7ft of west swell, with a 14-second period – that’s a long, powerful groundswell. The energy is strong, and the wind is a light breeze from the south at 6 mph, making it glassy clean. The wave comment says excellent surf conditions for experienced surfers. That’s the day you want to be on the water. The afternoon stays clean with 7ft and a 12-second period.
Saturday the 12th and Sunday the 13th of September still have some clean waves, around 5ft to 6ft, glassy on Sunday morning. But the Friday is the one to chase.
Perranporth can get crowded, and with a day like that Friday, expect a lot of company.

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.
