The Lowdown
G’day, Rusty here.
Alright, we’re sizing up the next 16 days at Perranporth and it’s a tough go. Most of this stretch is junk—choppy, cross-onshore winds and weak, messy swell. There’s a big gap in decent surf right from the start.
The one bright spot lands on Saturday, 22 August. Morning brings 0.6m of west swell with a period of about 10 seconds, combined energy just 114 (weak to moderate), but the clincher is a light offshore easterly breeze. That’s clean, glassy conditions. Crowds are sometimes an issue here, so you might have company, but this is the best of the lot. Water temp is about normal for this time of year.
After that it’s dry. Sunday the 23rd through the end of August: tiny waves, cross-shore or onshore winds, poor surf. Friday 28 August sees some size—1.9m to 2.0m—but it’s hammered by strong cross-onshore wind and a short 6- to 8-second period. The combined energy is 275 to 442 (moderate to strong), but with wind like that, it’s a blown-out mess. This is better suited to kite surfing than paddling.
Saturday 29 August brings the biggest swell: 2.2m from the west, 8-second period, combined energy at 623 to 638 (very strong). But again, cross-onshore wind trashes it. At that size, it’s for experts only.
From Sunday 30 August onward, size drops, winds stay messy, and there are storms and rain in the mix. No more windows of clean surf. So your only play is Saturday 22 August morning. After that, we’ve got a long, bleak run. It’s a quiet spell, but forecasts can change. Hang tight.
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.
