The Lowdown
Right then, let’s have a look at what’s on the cards for the next couple of weeks. It’s a bit of a rough start, but there’s a couple of windows that might just make it worth hanging in there.
We’re kicking off with a bit of a flat and messy spell. From Thursday the 27th of August right through the first week of September, the combo of small swell and funky, onshore wind is just not doing us any favours. The wave energy is weak to moderate at best, with combined energy readings in the low two-digit and three-digit range. The wind is mostly cross or cross-onshore, and often fresh or strong, so the surface is going to be pretty lumpy and choppy. It’s a long stretch of days where it’s just not worth paddling out.
The first real glimmer of hope comes on the morning of Wednesday, the 2nd of September. Perranporth (Cornwall) will be seeing a glassy window with the wind dropping to just 3 mph from the WSW. The swell is only 3 ft from the west, with a short period of 6 seconds, so it’s not going to be ripping, and the combined wave energy is a weak 80. But it’s clean, and that’s a rare thing right now. It’s surfable, but it’s very ordinary, so manage expectations.
After that, we’re straight back into a week of poor conditions. The wind swings back onshore and gets strong again, with some rain and storms thrown in. The swell does pick up, with combined energy readings reaching into the four-digit range (strong) on the 5th of September, but it’s all blown out. Big, messy, strong cross-onshore wind. This is more of a kite-surfing setup than a clean paddle session.
The final window worth a mention is the morning of Monday, the 7th of September. A light offshore breeze from the NW, with a 8 ft swell from the WNW. That’s a solid size, tipping it into expert territory. The wind is light, so it could be clean, but the period is a short 8 seconds, and the combined energy is a strong 695. It’s a marginal call, but it’s the best we’ve got in the second week. The rest of the 8th to the 11th is more of the same messy cross-onshore wind and small to moderate swell, with nothing to get excited about.
So, the standouts are the glassy Wednesday morning, 2nd September for the clean conditions, and the Monday morning, 7th September for the bigger swell and offshore wind, if you’re an experienced surfer.

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.
