The Lowdown
Alright, folks, Rusty here. Let’s be honest with you right off the bat: the next couple of weeks are looking pretty grim for a proper paddle. We’ve got a lot of small, weak, and messy conditions on the menu. The good news? There’s a little window of clean, rideable surf mid-week that’s worth getting excited about, and the water’s sitting at a comfortable 65° – a touch warmer than usual for this time of year, which is always a bonus.
The first few days are a total write-off. Saturday the 8th and Sunday the 9th are showing next to nothing – we’re talking ankle-biters at 0.7ft to 1ft. The energy is weak (15-21 in the combined swell energy) and even when the wind is offshore, there’s just no swell to work with. You’d be better off fixing your dings or going for a long walk.
Monday the 10th stays poor, with a bit of a bump from the north creating some cross-chop. Tuesday the 11th has some offshore wind, but the swell is tiny and inconsistent. We’re still waiting.
Now, here’s the one to circle on the calendar: Wednesday the 12th of August. Finally, something clicks. The morning shows a clean 3ft from the west with a light cross-offshore breeze, and the energy jumps into the moderate range (125). The afternoon cleans up even more with light easterly winds and a similar 3ft west swell (136). It’s not big, but it’ll be clean and make for some fun, rippable waves at Perranporth. This is the standout of the whole stretch, no question.
After that, it’s back to the grind. Thursday the 13th gets a little more size (4ft) but the northwesterly wind swings onshore and chops it all up. The energy does climb though (269 in the morning), so there’s some push, but it’ll be messy. Friday the 14th is similar – onshore and poor.
The weekend of the 15th and 16th is a mess of lumpy, cross-onshore slop with short, weak periods. The swell direction swings to the north, which isn't ideal. We are looking at a couple of days of poor surf conditions. Monday the 17th brings in some rain and fresher winds – just ugly. The next couple of days after that, the 18th and 19th, see the swell pick up to around 3ft – 5ft, but it’s all short-period windswell with onshore winds. Not worth your time.
Thursday the 20th is the next time we see any significant size, with the swell hitting 5ft in the morning (combined energy 310) and 5ft in the afternoon (337). But it comes with a moderate cross-onshore wind and short, 8-9 second periods. It’ll be a lumpy, challenging close-out, likely only for the local rippers. For most of us, it’s a look-and-decide day, not a paddle-out day.
The final stretch from the 21st to the 23rd fades away into small, choppy leftovers. There's a tiny glimpse of clean conditions on Sunday morning the 23rd, but the swell is a weak 2ft. All in all, it’s a bleak 16 days, with that one diamond in the rough on Wednesday the 12th. Get on it if you can.
Stay salty.

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.
