The Lowdown
Imperial:
Alright, Rusty here. Let's talk about what's on offer, and fair warning, it ain't much for a while.
We're looking at a proper dry spell for decent waves. From Tuesday, August 25th, right through to Friday, September 4th, it's pretty much a bust. The swell is either tiny or the wind is just destroying everything. You'll see waves, but they'll be choppy, cross-off, and generally miserable to paddle out in.
Now, there’s one little window that could be interesting. On the morning of Friday, September 4th, Perranporth might finally wake up. The wind is set to be side-shore at 12 mph, which is okay, and a 6ft swell from the WNW with an 11-second period is rolling in. That's proper groundswell energy, and the combined energy reading is 829, so there's some real punch behind it. It's not a dead cert, the model has a question mark over the tide, but it's the only highlight in this whole forecast. The water is sitting around 65°, which is a touch warmer than usual for now.
After that, the wind cranks up again, blowing strong onshore and turning the surf into a lumpy, messy challenge. Monday, September 7th, sees some serious size – up to 12ft – with a massive 2009 combined energy reading, but with 25 mph onshore winds, it'll be a messy, difficult beast. Anyone over intermediate level might get a few, but for beginners, anything over 5ft is a no-go, and over 8ft is strictly for the experts. Between these strong, onshore wind days, this setup is looking more interesting for the kite crew than us on our foamies.
Keep the board in the shed for now.
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.
