The Lowdown
Alright folks, Rusty here. Let’s talk about what we’ve got coming down the line for Rincon - Rivermouth.
First up, it’s a frustrating start. The beginning of this forecast window is pretty flat with weak, short-period leftovers. We’re looking at a couple of days with barely a ripple, not worth paddling out for.
Things start to show a bit more promise towards the end of the week. The first real glimmer comes in on Friday morning, the 28th of August. A nice pulse of longer-period swell from the SSW will push in, with wave heights around 2ft. The real story here is the period hitting 19 seconds – that’s proper groundswell energy, giving the waves some shape and push. The winds will be light and cross-offshore, keeping the faces clean.
The standout window, though, is the weekend – Saturday the 29th and Sunday the 30th. Saturday afternoon looks like the pick of the bunch. The swell will be consistent at 3ft from the SSW with a long 16-second period. With clean, cross-offshore winds, it will be about as good as it gets for this stretch. The water temp is running at 70°, which is over 7° warmer than usual for this time of year – that’s pretty unusual, so you’ll feel that bathwater. Keep in mind this is a point break, so those long-period swells will wrap in beautifully. The combined swell energy will be solid, hitting 322 on Saturday afternoon.
The following week is a mixed bag. The swell drops off a little but holds at a surfable size. Thursday, the 3rd of September afternoon, and Friday, the 4th of September afternoon, both show clean conditions with cross-offshore winds and a good 3ft and 2ft swell respectively from the SSW. The period remains long, keeping things fun.
Into the second week, the surf gets smaller and less consistent. There’s not a lot to get excited about, but a few afternoons might offer a knee-high wave for the patient. Just be aware that this spot can get crowded on the better days, so you’ll have company.
So, if you’ve got a window, make it Saturday the 29th or Sunday the 30th. It’s not huge, but it’s clean, long-period, and warm. Don’t sleep on it.
Rusty.
