The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
Right off the bat, it’s a bit of a rough start. We’ve got a solid 8ft west swell hitting Perranporth on Monday the 31st of August, with some serious energy behind it (1352), but it’s blowing a fresh 19 mph onshore from the NW. That’s a write-off. The wind sticks around onshore for days, and the waves are mostly messy, lumpy, and choppy. Honestly, for the first week, it’s a total battle. Tuesday the 1st of September morning sees the swell drop to 4ft, but the wind is cross-on from the WSW. It’s just not clean. The water is about 65°, which is a touch warmer than normal for this time of year, so not a bad temp, but it’s not making up for the wind.
We’re looking at a long stretch of poor surf conditions. The first real glimmer comes on Sunday the 6th of September. The morning brings a clean, cross-off breeze from the SSE at 9 mph, with a small 3ft west swell. The energy is weak (119), but the conditions are clean. It’s surfable, but very ordinary. That’s the only window with a decent wind state all week.
The next standout is far out. Monday the 14th of September morning brings a bigger 6ft west swell with a nice 10-second period. The wind is onshore from the WNW at 9 mph, which is a light breeze, but the energy is strong (1263). The guidance says it’s marginal, and the wind is onshore, so it’s not a classic. But it’s the most promising wave size we’ve seen in a while. The afternoon of the same day jumps to a 6ft swell from the WNW with a very long 15-second period, and the energy is even higher (1563). The wind is onshore from the WNW at 12 mph, so it’s a bit of a shame, but that long period will make the waves meaty. A long period west swell like that is best for a point or reef, but Perranporth is a beach break, so it might be a bit straight and walled up.
Best on offer: I’d have to say the morning of Monday the 14th of September is the pick. The 6ft west swell with that 10-second period has good energy, and the light onshore wind is manageable. It’s not perfect, but it’s the best of a pretty average bunch. The other morning worth a mention is Sunday the 6th of September for the clean conditions, but the swell is tiny. Overall, it’s a lean run, and we’re mostly waiting for that second week to show some promise.
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.
