The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next couple of weeks for Perranporth are a bit of a slow burn. Don’t expect any fireworks early on. We’re looking at a long stretch of tiny, poor-quality surf before things finally start to rumble in the second week.
The water is sitting at 65°, which is a touch warmer than normal for this time of year, so at least it won’t be a shock to the system.
Right now, through the first week of August, it’s flat. We’re talking ankle-biters. From Friday the 7th right through to Tuesday the 11th, the swell is a pathetic 0.3ft to 0.5ft, with weak energy (22 to 36) and short periods. The only saving grace is a couple of clean windows: Saturday morning has a light SE offshore, and Tuesday gets a fresh ESE offshore, but honestly, there’s nothing to push you into. You’d be fighting for dribbles.
The next gap is a real drag. From Wednesday the 12th up to Tuesday the 18th, we get a bit more size – 0.7ft to 1ft – but it’s all onshore or cross-onshore. The wind is coming from the NW mostly, which is messy for this spot. The energy picks up a bit (133 to 388), but it’s all wind-chop and slop. The best of this period is Thursday the 13th with a 1.0ft to 1ft swell from the west, but that NW wind is just ruining it. Not worth paddling out for.
Then, finally, we get a pulse. The standout here is Wednesday the 19th of August. The morning shows a solid 2ft swell from the west, with a period of 8 seconds and a combined energy of 422. That’s moderate to strong energy. The wind is a light north cross-shore – just a whisper – which will keep it clean. This is the best looking surf on the whole forecast. It’s got some grunt, but at 2ft it’s getting into the intermediate zone, a bit spicy for total beginners. The afternoon gets messy with a 2ft swell and a strong cross-onshore wind, so hit the dawny.
The week after that, from Thursday the 20th to Saturday the 22nd, it stays big – 1ft to 2ft – but again, the wind is mostly onshore or cross-onshore from the west. The energy is massive (306 to 658), but it’s going to be a bumpy, choppy mess. It’s a bit of a washout for a paddle board, but with that kind of wind and size, it’s looking more interesting for the kite crew.
So, bottom line: the only real window to get excited about is Wednesday morning the 19th. That’s your best bet. Everything else is a case of “leave the board in the van.”
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.
