The Lowdown
Alright, this is Rusty. Let’s talk about what’s happening at Perranporth.
You’re looking at a tricky stretch here. The first few days are tiny and not really worth paddling out for, unless you’re on a foamie and just want to get wet. The surf really doesn’t start offering anything decent until later in the second week, so we’ve got a long gap with not much to get excited about. Keep the board in the van.
The best bet in the whole 16-day window is going to be Monday the 24th of August, but there’s a major caveat. We get some serious swell rolling in – about 12 feet early Monday morning from the west, with a moderate combined swell energy of 1970 (strong to very strong). That’s a lot of water moving, and with onshore winds from the west-northwest at 28 mph, it’s going to be a raw, blown-out mess for most. This is definitely for experienced surfers only, and honestly, with that wind, the setup looks more interesting for kite surfing than a clean paddle session. The period is 10 seconds, so it’s not a super long groundswell, but at that size, it’s a beast. Conditions are marked as poor, so don’t expect any kind of clean face.
The other date to keep an eye on is Sunday the 23rd of August. You’ll get 6 feet from the southwest in the morning, with combined energy around 458 (strong). Onshore and cross-onshore winds again though, so it’ll be choppy and cross-choppy. Again, not your classic clean day.
Because we’re talking about Perranporth, the water temperature is about 66°F, which is a touch warmer than normal for this time of year, so you might not need the thickest wetsuit just yet.
Overall, the next two weeks are a long wait with very little that’s clean. If you’re desperate, the biggest size comes late in the window, but it’ll be rough. Most days are blown out or too small. Hang in there, but don’t plan any dawn patrols you’ll get excited about.
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.
