The Lowdown
Alright, let me take a look at what we've got here. It's a bit of a grim picture for Perranporth over the next couple of weeks, to be honest. The whole 16-day window is pretty much a write-off. We've got a long stretch of poor conditions, so don't get your hopes up for any decent paddle surfing for a while.
The first surfable suggestion doesn't pop up until Saturday the 5th of September. For over a week before that, it's all fresh onshore winds, lumpy chop, and messy swells. The swell energy is moderate to strong, with values like 260, 1122, and 1263, but it’s all blown out by strong winds – way more interesting for a kite surfer than someone on a longboard.
Even when that Saturday the 5th rolls around, it’s only a marginal call. The morning looks a bit messy with a light cross-onshore, but the afternoon shows some real promise. We get a light offshore breeze from the ESE at 6 mph cleaning things up on a 6 ft W swell. The period is 10 seconds, so there’s some decent shape there, and the combined energy is 540, which is moderate. That’s your one true standout, the only session where the stars align for a clean wave. Get on it if you can, because it doesn't last.
Sunday the 6th goes straight back to poor with strong cross-onshore winds, and the rest of the run is filled with choppy conditions or tiny, weak swells. There is a brief moment on Wednesday the 9th with clean, knee-high waves, and then another weird one on Thursday the 10th with a clean 2 ft, 12-second groundswell, but it's only 24-74 energy and it's blowing a fresh 22 mph breeze, so it’s not worth your time. The second week is just a blur of poor surf and messy winds. A fairly consistent blank run like this is just the way it can be around here sometimes.

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.
