The Lowdown
Alright, let’s break down the next couple of weeks at Perranporth. It’s a slow start, I’m not gonna sugarcoat it. The first few days are flat and messy, with onshore winds making a mess of things. The water’s about 66°, which is a bit warmer than usual for this time of year, so at least it’ll be comfortable while you’re waiting.
From Sunday the 9th through to Tuesday the 11th, we’re looking at waves around 0.7ft to 1ft. Winds are mostly cross or cross-on, and the combined swell energy is weak, barely getting into double digits. It’s a total washout. The first real sign of life comes on Wednesday the 12th. The swell bumps up to 3ft to 3ft from the west, with a period of 9 to 10 seconds, and the wind swings cross-offshore, going light and clean. The combined energy climbs to 125 and 142 – still moderate, but it’s surfable. You’ll find some waves, but they’re nothing special. It’s an improvement, but it’s not a standout.
From Thursday the 13th through the weekend, it’s a rough run. The swell gets a bit bigger, hitting 4ft to 5ft, but the wind is predominantly cross-on from the north, leaving the surface choppy and lumpy. The energy lifts into the 200s, but it’s all for nothing with that wind. The period on the 16th (Sunday) drops to 6-7 seconds, so it’s just windswell junk. There’s a big gap of nothing really worthwhile until we get to the following week.
Now, the best bet in the whole 16-day window is shaping up for Monday the 24th. The swell is the biggest we’ll see, holding around 5ft to 5ft from the west, with a period of 8 to 9 seconds. The combined energy is strong, registering 432. The wind is light and cross from the NNE, so it’ll be clean with just a few small crossing ripples. It’s a marginal forecast, but of all the options, this is the one. The size is pushing into the intermediate zone, but it’s not too big for a confident surfer. The cross-shore wind will keep it lined up better than anything else in the forecast. Tuesday the 24th afternoon is also worth a look, with similar conditions, though the energy drops a touch to 360.
Honestly, it’s a challenging run. If you’ve got a kite, some of those windy, choppy days from the 15th to the 17th might be more fun than a paddle. But for a surf, you’re waiting for that Monday the 24th.

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.
