The Lowdown

Alright, let’s break down Perranporth in feet and miles per hour. The next week and a half is a bit of a write-off, to be honest. The water’s about 66°F, which is a touch warmer than normal for this time of year, but that’s about the only good thing. The wind is mostly onshore, and the waves are just a messy, choppy mess.

We’ve got a run of poor surf from Sunday the 16th all the way through the end of the week. There’s some size in the middle of the week, with the combined energy hitting moderate levels, but the wind is ruining it – 25 to 35 km/h onshore, making it lumpy and ugly. That 8ft swell on Thursday 20th will be a proper mess, only for the experts if they’re really keen.

You get a clean spell on the 25th and 26th of August with some offshore winds, but the swell is tiny – less than a foot of slop. Not worth it.

The only real standout comes on the morning of Monday the 31st of August. That’s your best bet. You’ve got a 7ft groundswell from the west, with a clean 8-second period, and the combined energy is strong. The wind is light and offshore, so it’s going to be glassy. This is the one to save your energy for. The crowds at Perranporth can be a thing sometimes, so get down early.

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.
