The Lowdown
Right then, let's have a look at what's on the cards for the next couple of weeks. To be straight with you, it's a bit of a mixed bag. We've got a few windows where the swell shows up, but the wind is going to be the big boss here, and for the most part, it's not playing ball. The water's sitting at about 65°, which is a touch warmer than usual for this time of year, so at least you won't be freezing your bits off.
The first half of the run is pretty grim, if I'm honest. We start off Tuesday morning the 25th with a tiny bit of knee-high west swell pushing in at 2ft, and the energy is weak (63). The wind is a light cross-off from the east, so it's actually clean, but there's just no push. By the afternoon, a bit of an ESE offshore breeze kicks up to 18 mph and the swell nudges up to 2ft, but it's still just ordinary. You could get a wave but you'd be working hard for it.
Wednesday the 26th is much the same story – small 2ft west swell, clean enough but gutless. The energy is low (60). Thursday the 27th is where it starts to get messy. A bit more swell mixes in from the southwest, hitting 4ft by the afternoon with moderate energy (144), but the wind swings onshore and gets fresh, making it choppy and lumpy. Not worth the paddle.
Friday the 28th through to Monday the 31st is a write-off for quality. Swell picks up, getting up to around 7ft over the weekend, and the combined energy gets serious (up to 648), but it's all blown out by strong cross-onshore and onshore winds. It's going to be a washing machine out there. For the experienced lads, that 7ft Monday morning swell might have some grunt, but with a howling 22 mph onshore wind, it's a battle. Honestly, that setup looks more interesting for the kite surfers than us paddle guys.
Entering September, Tuesday the 1st sees the biggest swell of the period so far – a solid 10ft from the west with a very strong energy reading (1814). But again, it's cursed with a fresh cross-onshore wind. That's expert-only territory, and even then, it's going to be a messy, lumpy mess. Wednesday the 2nd drops back to a more manageable 6ft, but it's still cross-shore with chop.
The real standout – and I mean the only real standout in the whole 16 days – is looking like Tuesday morning the 8th of September. Finally, the stars align. We've got a solid 5ft west swell rolling in with a decent 9-second period, and the energy is moderate (326). The wind is a light cross-off from the south at just 6 mph. That means clean, peeling lines. For Perranporth, this is the session to pencil in. It's the best on offer, no question.
After that, Wednesday the 9th sees another pulse of much bigger swell, 8ft with a long 11-second period and massive energy (1466), but the wind is onshore again. It's a shame because that groundswell has the power, but it'll be blown out.
So, to sum it up: don't get excited for the next week and a half. It's a long, frustrating gap of onshore slop. Hold out for that Tuesday morning session on the 8th at Perranporth. It's the only day where the wind gives us a break and the swell has some proper shape.

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.
