The Lowdown
Alright, Rusty here, lookin' at the charts for Perranporth over the next couple of weeks. Gotta be straight with you; it's a pretty grim stretch for paddling. The first half of the outlook is a write-off.
We're kickin' off Monday the 24th with barely a pulse. The sea's flat and we've got 19 mph offshore wind blasting across a 0.7 ft swell. No way you're gettin' a wave. This sorry state of affairs drags on through the rest of August and into the first week of September. The surf is small, onshore winds are a mess, and the scores are rock bottom. There's no real recommendation to be made for over ten days here.
Finally, as we creep towards Saturday the 5th of September, we get some size. The morning shows 8 ft swell from the west with a 10-second period, but the light breeze is onshore, making it a bit of a washout for quality. The wave energy is reading 1513 (moderate to strong), but it's not clean.
The best chance, and I mean the *only* chance worth mentioning, looks to be Monday the 8th of September. By the afternoon at Perranporth, we've got a 8 ft west-northwest swell with a 12-second period—that's proper groundswell energy, reading 1575. It's a bit hefty for the average surfer, but the wind is a gentle cross-shore breeze, keeping the chop down to a minimum. It’s not the cleanest you've ever seen, and it's over 8 ft so you'll want a bit of experience under your belt, but after all this nothing, it's the only window where a wave might actually hold its shape.
The water's still a touch warmer than normal for the time of year at 64°, which is nice, but don't expect those super long rides. The swell's a bit big for the beach break, so it might close out in sections.
Look, the rest of it is windblown junk or just too big and onshore. If you're desperate for a paddle, keep an eye on that Monday the 8th, but don't hold your breath for anything before that.
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.
