The Lowdown
Alright, Rusty here. Gonna level with you – this one’s a test of patience. There’s a long dry spell before things finally line up.
Over the full 16-day stretch for Perranporth, the first week is pretty much a bust. From the 1st of September right through the 13th, you’re looking at a lot of poor surf. The wind’s a mess – mostly cross-onshore or onshore, making things choppy or lumpy. You’ll see some moderate swell energy (from 196 to 917 in the combined reading), but it’s all blown out. The water’s a touch warmer than usual for this time of year.
There’s one small bright spot early on – the morning of Saturday, September 5th. The wind goes glassy from the north at 3 mph, with a small 4 ft groundswell from the west at a long 10 seconds. The energy’s moderate (232). It’s surfable but very ordinary – barely worth a paddle. The surface will be clean, but the waves are small and dull.
Then, on Monday, September 14th, it finally pays off. This is the best day of the whole outlook. Skies are clear, with light offshore winds from the southeast at 6 mph in the morning, turning glassy by the afternoon with a light south-southeast breeze. The swell hits a clean 4 ft from the west, with a long 12-second period – that’s proper groundswell. The combined energy is solid, reading 411 in the morning and 404 in the afternoon. This is the one: clean lines, good shape, and a friendly size for intermediates. With that long period, watch out for it running a bit straight on the beach break, but it’ll be fun. Crowds are *sometimes* an issue here, and on a day like this, you’ll have company.
The next morning, Tuesday the 15th, still has some juice – another clean, offshore start (southeast at 6 mph) with smaller 3 ft waves from the west at 11 seconds. The energy drops to 231, but it’s still a nice, glassy session. By Wednesday the 16th, the clean window shuts as the wind turns cross-shore and then cross-onshore again.
Bottom line: mark your calendar for Monday, September 14th. That’s your best shot. Everything before is just waiting around.
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.
