The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for the next couple of weeks.
To be straight with you, the outlook starts off pretty flat. For the first few days, we’ve got tiny waves and mostly poor conditions, so don’t get your hopes up. The first bit of real promise comes in on the morning of Wednesday the 12th of August, and even then, it’s a bit of a mixed bag.
The standout session is going to be the morning of Wednesday the 12th of August. We’re looking at a clean 3 ft swell from the west, with a period of 10 seconds. The wind is strong offshore from the southeast at 25 mph, which will keep the face clean, but that strong breeze will make paddling into these waves a real grunt. The combined swell energy is moderate (125), so there’s a bit of push behind it, but it’s not perfect. The water temp is about average for this time of year.
Our main spot here is Perranporth, which is a fairly exposed beach break. The best wind direction for this setup is from the west, but we’re getting a west swell, so there’s a decent match. Keep in mind, Perranporth can get crowded sometimes, so you won’t be alone out there.
The afternoon of the 12th of August is a step down, with the same 3 ft swell but a lighter offshore wind and a slightly lower combined energy (108). It’s still surfable, but very ordinary.
Looking further out, there’s a spike in size on the 18th of August, with a 8 ft swell from the west-northwest, but it’s coming in with a short period (8 seconds) and onshore winds. That’s borderline messy and too big for anyone but experts. The combined energy is strong (987), but the quality is poor.
The week two window is a bit of a gamble. The morning of the 20th of August sees a tiny 2 ft west swell, clean with light cross-offshore winds from the east. It’s surfable, but you’ll be fighting for scraps. The 21st of August morning has a 3 ft west swell with a short period (5 seconds) and clean light winds, but it’s weak (92 combined energy). The afternoon of the 21st of August gets a 5 ft west swell, but it’s poor quality.
To be honest, if you’re looking for a reason to get wet, that Wednesday the 12th of August morning is the only real highlight. The rest of the window is pretty grim, with long gaps of poor surf or onshore/choppy conditions. It’s a quiet period for the area, so don’t be surprised if you don’t get many waves.
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.
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.
