Perranporth Surf Forecast and Surf Report

G’day, Rusty here. It’s a grim run ahead for Perranporth. We’ve got a solid 16-day window, but honestly, there’s not a session in there that gets the blood pumping. The pattern is dominated by onshore, cross-shore, and generally messy wind, with the odd burst of proper size but zero quality. The forecast starts with nothing worthwhile, then we hit a long, ugly stretch of poor conditions.

The first days are a write-off. Friday the 28th (morning): 3ft WSW swell with a short, weak 5-second period, cross-on at 19 mph, and only 74 combined energy—flat and chopped. That afternoon is slightly bigger at 5ft, but the wind swings and it’s still poor. Saturday the 29th gets worse: 5ft but a near gale cross-shore at 34 mph in the morning (248 combined energy), then a 12ft onshore mess that afternoon with a whopping 1872 combined energy, but the wind is howling—zero quality. Sunday the 30th is more of the same: 6ft and 7ft across the day, cross-on and cross-shore chop. Monday the 31st has some size, 10ft in the morning with 1476 combined energy, and the wind goes onshore, but the wave comment says “poor surf conditions”—it’s blown out, no shape.

That first week is a total loss. Tuesday 1st September through Thursday 3rd are small to moderate cross-on slop, and Friday 4th brings a 6ft swell with a 13-second period (long period, proper groundswell) and 1123 combined energy, but it’s hammered by fresh cross-onshore wind at 22 mph. The period is long enough to offer better shape potential, but with the wind on it, that’s dead in the water. Saturday 5th morning shows a glimmer: 4ft from the west, 11-second period, onshore wind from the NW at only 6 mph, and a “clear” sky—combined energy 293, but still flagged “poor surf conditions.” It’s clean-ish but tiny and lacking push.

The gap is real. From the start up until the morning of Tuesday 8th September, you won’t find a single recommendation worth paddling out for. That’s over 11 days of grovel. Then on Tuesday the 8th morning, we finally see something surfable: 2ft from the west, 8-second period, with a cross-off breeze from the ENE at 6 mph, and the wave comment says “surfable waves but very ordinary conditions.” Combined energy is only 54. It’s clean, but knee-high dribble. That afternoon gets glassy—NE wind at 3 mph, 1ft swell—but it’s almost flat. That’s the only window of clean, glassy conditions in the whole outlook. Not a standout, just a momentary relief.

The rest of the second week picks up size again, but the wind spoils it. Wednesday the 9th afternoon hits 8ft with a sharp 8-second period and 850 combined energy, but fresh cross-shore wind at 22 mph ruins any chance of order. Thursday the 10th is a full-on storm: 10ft WNW swell, 9-second period, 1368 combined energy, but a near gale cross-on at 34 mph—blown out. After that, it fades: Friday 11th to Saturday 12th September drop back to 4ft and smaller, with onshore winds cleaning up slightly, but the energy’s gone (236 down to 69). No standouts.

Perranporth is fairly exposed to swell from the west, and the optimum is W, which comes through often enough, but the wind angles just never line up. The consistency here is “fairly consistent,” so normally you’d get a few clean ones, but this 16-day run is a blank. It happens—sometimes the pattern locks in and you just wait for the next shift. For now, the setup is more interesting for kite surfing than paddle surfing, especially on those 8ft+ days with strong onshore flow.

If you’re desperate, the Tuesday 8th September morning is your only call—2ft, cross-off, clean. But I’d be patient. Forecasts change.
