The Lowdown
Alright folks, it’s Rusty here. Let’s be straight with you – the next couple of weeks are looking pretty grim for a proper surf. We’ve got a long stretch of small, junky waves and wind that’s all over the shop. It’s a waiting game, and we’ll have to be patient.
The first real chance of anything decent doesn’t show up until Thursday the 13th. Before that, it’s a whole lot of nothing. The surf is tiny, the period is short, and the wind is mostly cross-onshore, making it lumpy and messy. We’re talking knee-high slop at best. There is a brief moment on the morning of Friday the 7th where the wind goes glassy, but the swell is only about 1ft – pretty as a picture but not a wave to ride.
The morning of Thursday the 13th is where it starts to get a little interesting. The wind will be light and offshore, cleaning things up nicely. The swell is still small, around 3ft from the WSW, but it’s clean and rideable. The wave energy is only moderate (118), but for a beach break, it might just have a bit of shape. This is the first day you could actually get a few fun ones on a longboard.
Then, the morning of Friday the 14th is the one to circle on the calendar. This is the standout of the whole window. The wind will be dead glassy, the sky clear, and we’ve got a 4ft swell rolling in from the west with a 9-second period. The energy is up to 215, so it’s got a bit more punch. It’ll be small, but it’ll be clean and fun on the high tide. This is your best bet for a proper surf without getting blown off your board.
After that, the swell actually builds, but the wind turns onshore again and ruins it. By Saturday the 15th, we’ve got a 6ft swell, but the cross-onshore wind is going to chop it all to pieces. Sunday the 16th and Monday the 17th are similar – bigger waves, but poor conditions. The standout from the 18th is a 7ft swell with a 10-second period, but it’s straight onshore with a fresh breeze. That’s going to be a washing machine, and way too much for beginners. For the experts, it might be a bit of a mess, but on a beach break, it could be more interesting for the kite surfers than the paddle surfers.
So, keep your expectations low for the next week. The water temp is a touch warmer than normal for this time of year, which is nice, but the surf is pretty bleak. The only real window to get out is the morning of the 14th. It’s not big, but it’s clean and that’s about all we can ask for right 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.
