The Lowdown
Right then, let’s have a look at what’s coming down the tracks for this stretch of coast.
The next couple of weeks are a proper mixed bag. We’ve got a run of clean, punchy days around the middle of next week that look like the pick of the bunch. But before that, it’s mostly a write-off with onshore winds and lumpy, poor surf. Don’t get too excited about the first week – we’ve got about four or five days of mostly messy conditions to get through.
Tuesday 15th and Wednesday 16th are a no-go. The wind is howling from the WNW at 19 mph on Tuesday and cross-on Wednesday, with swell around 6 ft to 7 ft and a short period of 8 to 10 seconds. It’s all chopped up and weak for the size. The combined energy is moderate, around 441 to 934, but the quality is rubbish.
Thursday 17th stays poor. Strong onshore wind from the WNW at 22 mph, 7 ft swell, still a short 8-second period. This is messy, blown-out stuff. It’s more of a kite day than a paddle day, to be honest.
Friday 18th has some size – 7 ft from the WNW – and the period jumps to 13 seconds, which is proper groundswell energy. The combined energy hits 1249, which is strong. But the wind is cross-on from the W at 16 mph, making it lumpy. A lot of grunt but no shape.
Saturday 19th is more of the same: cross-on 6-6 ft, moderate energy around 464 to 625. Still ordinary.
Then we get a bit of a lull. Sunday 20th drops to 4-5 ft, the wind backs right off, but it’s still cross-on. Marginal. Monday 21st morning is the first glimpse of hope: the wind goes glassy, swell is tiny at 3 ft, but the period is a decent 10 seconds. Combined energy is low at 177. It’s surfable but very ordinary.
Now, here’s where it gets interesting. Tuesday 22nd is the standout. The morning has a light offshore from the SE at 6 mph, 4 ft swell from the W with a 12-second period – solid groundswell energy (582). Clean conditions. The Tuesday afternoon is even better: the wind swings to the ENE at just 3 mph (cross-off), the swell jumps to 4 ft from the WNW, and the period stretches out to a very long 16 seconds. The combined energy is a strong 1086. This is the best of the whole run – clean, long-period groundswell wrapping in. Keep in mind, with a 16-second period, it’ll have long lulls between sets, punching through the line-up nicely. Best at the points or reefs if you can find them.
Wednesday 23rd keeps the good vibes. Morning has a light offshore from the E at 6 mph, 5 ft from the WNW at 13 seconds (689 energy). Afternoon stays offshore but a little stronger at 9 mph, swell drops to 4 ft. Both sessions are clean and surfable.
After that, things fade. Thursday 24th and Friday 25th morning see the swell drop away – 2 ft to 3 ft – with fresh offshore winds. Not enough to ride. But Friday 25th afternoon perks up again: 4 ft from the W, 11 seconds, moderate offshore wind (16 mph from the SE), and 296 energy. Clean, but small.
Saturday 26th has some size – 5 ft to 5 ft from the WNW, 14 seconds (1024 energy) – and clean cross-off winds from the SE. It’s marginal because of the tide, but if the banks are right, it’ll be fun.
Then there’s a big one on Monday 28th – 15 ft from the W, 10-11 seconds. The combined energy is 3865 to 4160 – very strong. But the wind is onshore from the WNW at 12 mph. This is way too big for beginners (over 8 ft, only for experts). It’ll be a washing machine. Not recommended for paddle surfing; more of a spectacle.
Tuesday 29th drops back to 7-8 ft with a cross-on breeze and light wind. Still messy, and the size is still heavy.
Wednesday 30th finishes the run with 6 ft to 10 ft from the W and WSW, clean cross-off winds from the SE and SSE. The combined energy is 737 to 1343. It’s marginal with the tide, but the 10 ft afternoon session with clean winds could give a few expert waves.
So, to wrap it up: the real gold is Tuesday 22nd and Wednesday 23rd. That’s your window. Clean offshore flow, proper groundswell, and good energy. Don’t sleep on it.

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.
Perranporth is 9 km (6 miles) from Newquay. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Newquay. Newquay has rooms for a wide range of budgets as well as car hire and transport links.
