The Lowdown
Alright, surfers, Rusty here with a look at the next couple of weeks at Perranporth.
Honestly, it’s a pretty tough stretch ahead. We’ve got a whole lot of days where the wind and the swell just aren’t playing ball. The setup looks more interesting for kite surfing than paddle surfing for most of it, with strong, lumpy cross-onshore winds dominating.
The opening days from Thursday the 13th right through to the 19th are pretty much a write-off. We’re looking at poor surf conditions with moderate to fresh cross-onshore breezes kicking up a chop, and swell energy is weak, sitting in the low hundreds or even just double digits. There’s a pulse of energy on Wednesday the 19th, with the swell jumping to 8ft to 10ft from the WNW and combined energy hitting 1043 to 1790, but that’s coupled with 16 mph cross-onshore winds. It’s big, raw, and messy – definitely only for the experts if anyone’s keen, but don’t expect any kind of quality.
We finally get a little glimmer of hope on the morning of Friday the 21st of August. For the first time in the period, we see a clean, cross-offshore breeze from the East at 9 mph. The swell is small, only 3ft from the West with a 10-second period, but the conditions will be clean. The combined energy is weak at 145, so don’t get too excited, but by the afternoon it gets even better. The wind turns directly offshore from the East at 9 mph, and we’re looking at gentle offshore and clean conditions. The swell drops to 2ft, so it will be tiny, but for a short window it might be the best on offer for a longboard.
After that, it’s back to messy, windy conditions. Saturday the 22nd and Sunday the 23rd are mostly blown out. There is a note that on the morning of Sunday the 23rd, we’ve got a clean, cross-offshore flow from the SSE with 2ft swell from the West, but the combined energy is only 124. It’s surfable, but very ordinary.
The one real standout, such as it is, comes on the morning of Monday the 24th of August. We get a rare moment of glassy conditions with the wind from the WNW at only 3 mph. The swell is small, 2ft from the West with a 9-second period and combined energy of 101. It’s not going to be pumping, but for Perranporth in this window, clean, glassy surf is the absolute best we can hope for.
After that, the final days of the outlook are a return to strong, messy onshore winds and lumpy surf. A tough outlook, lads.
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.
