The Lowdown
Alright, let’s break down Perranporth for the next couple of weeks.
Honestly, it starts off pretty rough. From Saturday the 15th all the way through to at least Tuesday the 18th, the surf is poor. Tiny little waves, weak energy, and the wind is all wrong – cross-shore, onshore, choppy. Not worth paddling out.
Wednesday the 19th sees the swell pick up a little, with 4ft from the WNW but with a short, weak period and onshore wind. It’s still poor. Thursday the 20th gets a bit bigger, 5ft from the WNW, and the energy jumps to moderate, but the wind is still onshore and fresh. Just messy.
Friday the 21st is more waist-high slop. Saturday the 22nd shows a change – the wind goes offshore and cross-off in the afternoon, with 3ft from the W and WNW. It gets a “surfable” tag, but it’s nothing special.
Sunday the 23rd has a weird little blip: a tiny 0.7ft swell from the WSW with a very long 14-second period. That’s a long-period groundswell, but there’s almost no height to it. Not worth it.
The next week starts to look better. Monday the 24th brings 5ft to 6ft from the W with 8-second periods, and the combined energy jumps to strong. That’s a real step up. The wind is gentle cross-on, so it’ll be a bit bumpy but rideable. Tuesday the 25th keeps 5ft from the W, with light cross-shore wind and strong energy.
The standout for the whole 16 days is definitely Tuesday the 25th. You’ve got a solid 5ft west swell, a workable 8-second period, and strong energy in the water. The wind is light and cross-shore, so it should be clean. Perranporth is fairly exposed to that west swell, and the optimum direction is west, so it lines up nicely. It’s a fairly consistent spot, but sometimes it gets crowded, so get there early. Water temps are about normal for this time of year.
From Wednesday the 26th onward, it drops back to small, poor slop with strong winds for a few days. There’s a late pulse on Sunday the 30th with 6ft from the W, but it’s cross-on and choppy.
So, first week is a write-off. Your best bet by a long shot is Tuesday the 25th. Monday the 24th is a decent backup if you don’t mind a little bump. After that, you’re waiting again.

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.
