The Lowdown

Right, folks, Rusty here. Let's have a proper look at what's on the cards for the next couple of weeks. I've got to be straight with you – it's a grim picture for the most part. We're looking at a long stretch of poor surf conditions, with a few flickers of hope way out over the horizon, but nothing that's going to get you scrambling for your wetsuit just yet.

Alright, so the forecast kicks off Friday the 14th of August and it's not a pretty start. We've got a small 3-foot swell from the west at Perranporth, with a 9-second period, and the water is a touch warmer than normal at 66°. But the wind is onshore from the WNW, and the combined energy is weak (123), so it's all a bit of a mess. That sets the tone for the next several days.

The whole of the following week, from the 15th to the 24th of August, is a write-off. We're looking at a real flat spell. The swell drops to nothing, barely 0.7 feet at times, with long periods of 14 seconds, but there's no energy behind it. The wind is all over the place – cross, cross-on, and onshore – and it's keeping everything chopped up and ugly. The combined energy values are very low, often below 100, confirming it's just not worth paddling out. There's a brief moment on the 22nd and 23rd with clean cross-offshore winds, but the swell is virtually non-existent. It's a classic summer flat spell, and it's a long one.

Now, we finally get a bit of a pulse late in the run. On the 25th of August, the swell starts to build. By the morning of the 25th, we're looking at 6 feet from the WSW with a 9-second period, and the combined energy jumps to a strong 506. But the wind is onshore from the NW, so it's going to be a rough, messy storm surf. This is not a clean option.

The 26th of August gives us a glimmer, but it's a marginal one. The morning shows 4 feet from the west with a 10-second period and a gentle cross-shore breeze from the SW. The combined energy is moderate (335). It's a "marginal" call, which means the tide or conditions might throw a spanner in the works. It's the best of a bad bunch, but I wouldn't get your hopes up.

Then we get into another run of onshore winds and lumpy surf right through the 27th, 28th, and 29th. The 29th of August has a weird one: a 3-foot swell from the WSW with a very long 15-second period, which is a proper groundswell, and the combined energy is strong (426). But the wind is onshore from the west, so that long-period energy will be a tricky, bumpy beast. It's a real shame.

So, the honest truth is, there's no standout session in this 16-day window. The conditions are persistently poor, and the wind is almost always wrong for Perranporth. The best I can say is to keep an eye on the morning of the 26th of August, but even that's a long shot and a "marginal" call. For now, I'd say it's time to clean the wax off your board and wait for a better run.

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.
