The Lowdown
Alright, Rusty here, with the same news in feet and miles.
First off, I’ve got to be straight with you: the next 16 days are looking bleak for Perranporth. There’s not a single standout session in the whole window. The best we’ve got is a glimmer on Wednesday morning, the 12th of August, and even that is barely worth a mention.
We’re kicking off with Perranporth early on Wednesday morning. The water is a touch warmer than normal at 66°F – about 4°F above the usual for the time of year, so it’s notably mild. The swell is tiny, just 3 feet from the west with a 10-second period, giving a combined wave energy of 125 (moderate). The wind is offshore from the ESE at 12 mph, so the surf will be clean. It’s surfable, but the conditions are very ordinary. The score is a 1/10. It’s not good, it’s just the least bad slot. The break is fairly consistent, so if you’re desperate for a paddle, you could get a few small, clean waves. Crowds are sometimes a problem here, so you might have company.
After that Wednesday morning, it’s a long, grim stretch. From Wednesday afternoon right through to the end of the 16 days, the forecast is all “poor surf conditions” and scores of 0. The wind goes wrong, the swell gets messy, and the energy drops right off. Thursday the 13th sees a bump in swell to 4 feet, but the wind is cross-on and choppy. By Friday morning the 14th, the wind is onshore, and it just gets worse from there.
We’ve got a period of weak, jumbled swell with short periods – often 5 to 8 seconds – and the combined energy is mostly low to moderate (you’ll see readings like 79, 161, 183). The wind is a constant problem: cross-on or onshore, with fresh breezes up to 22 mph or even 25 mph. There’s a stretch from the 17th to the 25th where the swell is barely 1 feet to 2 feet – that’s flat, mate. The wind is still rubbish.
There’s a tiny flicker of hope on the 26th of August: a clean cross-offshore wind from the SSE, but the swell is only 2 feet with a combined energy of 82 (weak). Not worth getting excited about. Then the 27th of August brings a bigger swell – 4 feet from the WNW – but with a short, weak period of 6 seconds and cross-on wind, it’s just messy. The energy reads 201 (moderate), but with that wind, it’s a no-go.
Honestly, if you’re a surfer, you’re better off finding something else to do. The lack of any consistent, clean swell and wind alignment means we’ve got a 16-day gap with no real options. It’s a rare blank run, but it happens here. Forecasts can change, but right now, it’s a tough one to swallow.
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.
