The Lowdown
Alright, folks, Rusty here with a look at what’s shaping up for us. To be straight with you, the next couple of weeks are a bit of a mixed bag. We’ve got a long quiet spell to start, but there’s a serious pulse of energy waiting for us down the line that has me pretty keen.
Right now, the water is a touch warmer than normal for this time of year at 66°F. It’s a small comfort when there’s barely a wave to ride.
We’re looking at a real drought to kick things off. From now until the 21st of August, don’t bother getting your hopes up. There’s nothing worth paddling out for. The swell is tiny, the winds are messy, and the charts look flat and sad. It’s just not happening.
Then, things get interesting. On Saturday the 22nd of August, we’ve got a massive pulse of energy forecast. The combined swell energy is reading a huge 3259, which is massive. But here’s the kicker: it’s too big. We’re looking at an 12 ft swell from the WNW, packing a solid 11-second period. That’s going to be a beast, and for a spot like Perranporth, it’s just too much. The wind is a moderate cross-onshore, so it’s not going to be clean either. This is for experts only, and honestly, it’s looking more like a kite-surfing day than a paddle session. The morning of the 22nd might be the only window, but even then, it’s a heavy, blown-out mess.
That big swell drops off quickly. By Sunday the 23rd of August, we’re back down to 8 ft from the NW, but the period is a short 7 seconds, and it’s still lumpy. Not great.
Now, here is the real standout. Mark your calendars for Monday the 24th of August. Things finally come together. The morning is looking beautiful. We’ve got a tiny 3 ft swell from the west, but that’s riding a 14-second period, which is proper groundswell. Down at Perranporth, the wind is forecast to be glassy – dead calm – with a slight air from the southeast. The water will be clean as a whistle. The energy reading is a healthy 365, which for that size is nice and punchy. This is the pick of the entire outlook. It’s a small window, and it won’t be huge, but with those conditions, the banks will be working. Get on it.
After that, the 25th of August offers a clean, offshore morning with a 3 ft swell and 11-second period, but nothing that really stands out like the 24th.
So, to sum it up: don’t waste your time until the 22nd. The 22nd is a beast for the brave, but mostly a mess. The single, true standout is the morning of Monday the 24th of August. Glassy conditions, clean lines, and a long-period groundswell. That’s the one to go for.
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.
