The Lowdown
Alright, let’s get into it. The next couple of weeks are a bit of a mixed bag here at Perranporth. We’ve got some decent pulses of swell coming through, but the wind is going to be the real story – it’s going to mess with a lot of it.
The first few days are pretty grim. Thursday the 3rd is a write-off with a strong cross-onshore wind and messy, poor surf. Friday the 4th isn't much better, with onshore winds muscling up a 7ft windswell. The water is sitting at 64°, which is a touch warmer than normal for this time of year, so the sting is out of the air.
Then we get our first real window. Saturday the 5th. That’s the standout. We’re looking at a clean 5ft W/NW groundswell with a solid 11-second period and glassy conditions in the morning. It’s not huge, but the combined energy is moderate (467) and with those perfect winds, it’ll be super clean. It’s the best on offer by a long shot. You’ll want to be out there early.
Sunday the 6th is a bust. The swell drops right off to a weak 2ft (energy of 64) and the wind switches. Not worth the paddle.
Monday the 7th brings a big jump in size – a 8ft W groundswell with a very long 12-second period, and the energy is strong at 1480. But, the onshore wind is going to chop it up. This is one for experts only if they’re desperate, as the size and wind make it a beast. Tuesday the 8th is similar, with an 8ft swell, but the wind is cross-onshore, making it choppy and lumpy.
The rest of that first week and into the second is mostly small or wind-affected. There’s a glimmer on Thursday the 10th with a 6ft swell and strong offshore wind from the SE, but the period is a short 7-seconds, making it hard to paddle into. It’s clean but tricky.
The weekend of the 13th and 14th is tiny – we’re talking 3ft and below, with weak energy. Not really worth the wetsuit.
Now, looking way out to Tuesday the 15th of September, we get another interesting pulse. A 5ft W/NW swell with a very long 16-second period, packing strong energy (1035). This is a proper groundswell. The problem is the cross-shore wind. At a beach break like Perranporth, that long period might make the waves a bit too straight and fat. It’s a marginal call for the afternoon. That’s the only other one that might be worth a look, but it’s a long way off and the wind is the big question mark.
So, to be honest, if you’re looking to surf, circle Saturday the 5th on your calendar. Everything else is either too windy, too small, or too messy. It’s not a total blank run, but it’s going to be a waiting game for that one clean day.

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.
Perranporth is 9 km (6 miles) from Newquay. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Newquay. Newquay has rooms for a wide range of budgets as well as car hire and transport links.
