The Lowdown
Alright, this is Rusty checkin' in from the North Cornwall coast. It’s been a pretty grim stretch for a while, so let's get straight to it.
Right now, there is no surf worth paddling out for. We’ve got a solid week of onshore junk to sit through. Friday the 4th through to Thursday the 10th is a write-off – we’re seeing strong onshore winds and wind states that are just putting a real nasty chop on everything. Despite some solid swell showing up on Monday the 7th (moderate to strong wave energy around 1912), it’s all blown to bits.
The first real glimmer of hope comes on Saturday the 12th of September. The morning at Perranporth will see the wind swing offshore from the northeast with a light breeze. The swell is coming from the west at a clean 4ft, period around 10 seconds. It’s not huge, but the conditions will be clean, and the combined energy is weak (234). It’s a surfable wave but very ordinary. The setup is fairly exposed and it can get crowded, so it might be worth a look for a few small clean ones.
The next standout, and seriously the best on offer for the whole outlook, is Wednesday the 16th of September. The morning at Perranporth is going to be magic. We’ve got a glassy sea, zero wind from the northeast. The swell is a consistent 4ft from the west with a period of 11 seconds – that’s some proper long-period groundswell with decent energy for its size (328). The water temperature is about average for the time of year. For the intermediate surfer, this is the session to circle. Low crowds likely first thing, though it can get crowded. This is one clean, lined-up window.
After that, we fade back into small clean waves through the 18th and 19th, but nothing that really revs the engine.
So, to sum it up: suffer through the first week. Saturday the 12th gives you a small, clean morning. But Wednesday the 16th is the one – glassy, clean, and a proper long period swell. That’s the time to be out at Perranporth.
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.
