The Lowdown
Right then, let’s have a look at what’s on the cards for the next couple of weeks. To be honest, for the first few days, it’s a bit of a write-off. The surf just isn't there to get excited about. We’re looking at a real dry spell through until the 11th of August, with wave heights barely cracking 1 ft and the energy just isn't there. You’d be wasting your time.
Things start to stir on Wednesday the 12th. We’ll see a pulse of 3 ft swell from the west, with a bit of moderate energy behind it. The morning looks clean under a light easterly offshore breeze, but the waves are still pretty ordinary. It’s not until the morning of Saturday the 15th that we get a proper window. The wind drops to glassy, with a light WSW air, and the swell holds at 3 ft from the west. The energy is still just moderate, but that glassy surface will make it feel better than it is. It’s the best we’ve got in the early goings.
Now, the standout in this whole run is shaping up for the 21st of August. Friday morning sees a solid 10 ft swell from the west-southwest, packing strong energy. That’s a proper push. The catch? The wind is a strong 25 mph cross-shore from the southwest, making a mess of it. The break is fairly exposed and the swell direction is a perfect match for the optimum. This is a big, raw swell, but it’s going to be a battle. The wave period is short at 8 seconds, so it’ll be a bit lumpy and lack the real punch of a groundswell. This is expert-only territory, and the conditions will be more about survival than silky rides. It’s a powerful, honest swell, but you’ll have to work for it. The energy is dropping off by the afternoon, and the rain will push through.
The 16th of August also sees a bump, with a 6 ft swell from the west on the Monday morning, but it’s onshore and messy. The 21st is the only real, proper big-wave moment in the window, but it’s a rough one. The water temperature is about average for the time of year, nothing unusual there.
So, if you’re a beginner, steer clear of the 21st. If you’re an expert and want a piece of that raw power, it’s there, but don’t expect it to be pretty. The 15th of August morning is your best bet for a clean, manageable session.

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.
