The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks down at Perranporth (United Kingdom). I’ve got to be straight with you – this stretch is looking pretty rough for a while, but there might be a couple of moments worth getting excited about.
Right off the bat, we’ve got a long period of flat and messy conditions. The first solid swell I can recommend is a long way off. There’s a notable gap with barely anything worth paddling out for between late August and the start of September. The first real glimmer shows up on Saturday the 5th of September, but even then it’s only a marginal call.
The standout for the whole period – the one I’d mark on your calendar – is Monday the 31st of August. There’s a solid 8ft swell from the west, with a period of 10 seconds, and the wind is a clean offshore from the WNW. Combined energy is pumping at 1328 – strong energy that’ll punch through. This is one for the confident intermediate crew, because it’s a bit heavy for beginners. The waves should be well-shaped with that period, holding together nicely at Perranporth. The water’s sitting at 65°, a touch warmer than normal, which is always a bonus.
Another one worth a mention is Saturday the 5th of September morning. You’ve got 8ft west swell, 8-second period, light winds from the WSW that are cross-on. The energy is moderate at 746, but the wind is light enough that the surface should be okay. It’s listed as marginal, so tide could be a factor. It’s not the cleanest, but if you’re desperate by then, it’s the best option around.
Other than that, there’s a lot of lumpy cross-onshore slop, strong winds, and inconsistent junk. For the most part, this beach setup looks more interesting for kite surfing than proper paddle surfing.
Keep an eye on the 11th of September – some clean cross-offshore wind and 5ft to 5ft west swell, but it’s still a little uncertain that far out. I’d say stay hopeful but don’t book the day off work just yet.
Stay wet, stay keen.
Rusty.

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.

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.
