The Lowdown
Alright folks, Rusty here. Let’s take a good hard look at what’s going on for Perranporth over the next couple of weeks. I’ll be straight with you – this is a tough one. The swell is small, the wind is often a mess, and the surf quality is just not there for a solid paddle session for most of the run. There’s a long, quiet spell ahead, but one day does show a little promise if you’re patient.
The first chance to get wet comes on Wednesday, 12 August. The morning starts clean with a light breeze from the ENE, and a small 3ft swell from the west, with a period of 10 seconds. The combined energy is moderate at 124, so there’s a bit of push. The afternoon gets even better with a light offshore wind from the ESE, a clean 3ft west swell, and a period of 9 seconds. The energy is moderate at 139. This is the best of a very average lot. The swell is small, but it’s clean and ridable – perfect for a log or a fun mid-length. The water temperature is 66°, which is a touch warmer than normal for this time of year, so you won’t need a thick suit.
After that, things fall apart. From Thursday, 13 August through to Saturday, 22 August, it’s a long slog of poor surf conditions. The wind swings onshore or cross-onshore, the swell stays small and weak, and the energy drops into the low two-digit values. On Thursday, 20 August and Friday, 21 August, the morning does show a clean offshore wind, but the swell is tiny – only 2ft to 1ft – so it’s really just a flat-day special.
Then, on Sunday, 23 August, a big pulse of swell hits. We’re talking 10ft from the west-northwest, with a period of 9 seconds. The combined energy is a massive 1436, indicating very strong wave energy. But here’s the kicker – the wind is howling from the north-northwest at 15 mph, making it a cross-onshore mess. The surf quality is poor, and with that size, it’s only for experts. The beach break is going to be a churned-up washing machine. Honestly, it looks more interesting for kite surfing than paddle surfing.
The rest of the run into Monday, 25 August is poor, with onshore winds and weak, messy swell. The period does get very long at 15 seconds on Tuesday, 25 August, but with a tiny 2ft swell and a fresh onshore breeze, it’s not going to produce anything worth paddling out for.
So, the standout here is Wednesday, 12 August. It’s the only day with clean, ridable conditions. The crowds can be *sometimes* an issue at Perranporth, but with such small surf, it’ll be quiet. Don’t expect much after that. The forecast can change, but for now, it’s a waiting game.
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.
