The Lowdown
Alright folks, Rusty here. Let's have a look at what's heading our way for the next couple of weeks.
It's a bit of a weird one, to be honest. For the first few days, the swell is there but the wind is just all wrong. We've got a big lump of mediocre conditions to get through before we see anything worthwhile. A long period of waiting.
So, for The Breakwater-St Ives, it’s a pretty quiet start. From Monday the 14th to Thursday the 17th, the wind is howling from the southwest and west, cross-off and cross-on, keeping the surface messy. The swell is there, pushing up to 7ft on Thursday, but it's unsurfable with that wind, earning a big fat zero in the quality department.
We finally start to see a shift on Friday the 18th. The wind eases a touch, going more cross-shore, and the swell ticks up with some proper long-period energy at 13 seconds. Wave energy is strong (1611). The condition notes are still marginal, but this is the first real flicker of something surfable. Saturday the 19th and Sunday the 20th look cleaner with lighter cross-off winds, but the swell drops a bit and the period is all over the place.
The real standouts, the ones worth circling on the calendar, are Sunday the 27th and Monday the 28th of September. Sunday morning is looking absolutely pumping for the experts. We're talking a massive 12ft swell from the WSW with that long 11-second period and light offshore winds. The combined wave energy is enormous (3227). The guide says it’s just too big for this break for the average surfer – this is big, powerful groundswell that will be cleaning up the point. This is expert-only territory, but for those guys, it’s a genuine session for the memory bank. Be smart about it.
Monday the 28th is still sizeable at 4ft from the WSW, but the wind swings around to a light cross-on, making it a more manageable and marginal option after the big Sunday swell.
So here’s the bottom line: gritty and average for a long stretch, then a massive, expert-only pulse at the very end that could be the best thing on offer in a while. Keep your eyes on the 27th.
Rusty.
