The Lowdown

Alright, folks, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty grim for anything worth paddling out for. We’ve got a long stretch of small, messy, windblown surf ahead, with only a couple of brief moments that might get the heart beating a little faster. Don’t get your hopes up too much, but keep an eye on the horizon.

Right off the bat, Monday the 14th is a no-go. We're looking at around 3ft of short-period, weak stuff (38 energy) with a 12 mph onshore breeze messing it all up. It’s just a washing machine out there. Tuesday doesn’t offer any relief either, with cross-shore winds and a lumpy sea state. We’re treading water through the middle of the week with tiny, weak waves and onshore flow.

There’s a slight pulse of energy on Saturday the 19th, with the swell bumping up to 6ft (212 energy), but it’s coming with a 22 mph onshore wind. It’s going to be a close-out mess. Unless you’re after a battle, it’s not worth the effort. After that, the bottom really falls out. From Sunday the 20th through to Monday the 28th, we’re looking at a stretch of tiny, inconsistent surf, with most days seeing waves under 2ft and energy readings in the single digits to low teens. There will be some clean, glassy mornings around the 23rd and 26th, but with only 0.7ft on offer, it’s not even enough for a decent log.

Here’s the one bright spot, and it’s a long way off. On Tuesday the 29th, the charts are showing something a little different. The swell direction swings around to the ESE, which is not the usual SW we need here at Fishermans (Rhiw). We’re looking at a 3ft swell with a weak 4-second period. It’s still small, but the wind finally looks favorable, dropping to a light breeze in the afternoon. It’s a long-range call, so don't book the time off work yet, but it’s the only thing on the horizon that looks like it might have a pulse. It’s promising, but a long way out.

The water is sitting at 63°, which is a touch warmer than usual for this time of year, but that’s the only thing that’s out of the ordinary.

Hang in there. It’s a flat spell, but these things never last forever. Forecasts can change, and the ocean always finds a way to surprise you.

Stay salty,
Rusty

Further information to help with frequently asked questions about our surf forecast for Fishermans (Rhiw) 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.
