The Lowdown
Well, listen up folks, it’s Rusty here. We’ve got a bit of a mixed bag on the horizon for The Breakwater-St Ives, and honestly, for the next few days, you might want to find something else to do. The surf just isn't working for us for a good chunk of this forecast window.
The pattern starts off pretty rough. We’re looking at a solid week of onshore and cross-onshore winds, mostly from the west and northwest, that are just going to chop things up. Swell will be there, but it's going to be lumpy, messy, and a real battle. Paddling out for a close-out or a washing machine ride isn't my idea of fun. There’s some energy in the water, but it’s not organized, and the winds are killing any chance of clean waves. We're looking at a stretch from the 13th all the way through the 23rd where the quality is just not there. The conditions are just poor, plain and simple. There’s a bit of a pulse of longer-period swell around the 18th, but the wind is still messing it up, so don’t get too excited.
But hold on, because there’s a glimmer of hope. The standout window looks to be the 20th. On the Sunday morning, we get a break in the weather. The wind swings around to a cross-off from the southwest, and we’ve got a solid 7 feet of west-northwest swell at a long 14-second period. The energy is strong (1556). It says the morning is clean, and that’s the one to keep an eye on. The swell direction is just off from the optimum, but the size and the period are promising. That’s your best bet for a proper, clean wave. The water temp is about average for this time of year, so a good wetsuit is all you need.
Another one worth noting is the morning of the 24th. The wind is light and offshore from the south-southwest, and we’re looking at a clean 5 feet of west swell. It’s smaller than the 20th, but the conditions should be good. Don't expect it to be perfect, but it will be a hundred times better than what we’ve seen.
Beyond that, it’s a bit of a letdown again. The week after just gets messy again with more onshore winds and fading swell. The 27th and 28th are small and scrappy, with onshore winds. So, honestly, if you want a wave, your window is really the 20th, with the 24th morning as a backup. It’s a long-range call, so keep an eye on it, but that’s the one with the most potential.
Rusty.
