The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.
Right off the bat, I gotta be straight with you – it's a tough stretch ahead. We're looking at a long, dry spell with nothing really worth paddling out for. Things kick off with a bit of a whimper on Sunday the 6th. Fishermans (Rhiw) is seeing a weak 4ft SW swell, but it's wrapped in a strong onshore wind, and the energy is barely there (95). The water is sitting at 63°, which is a touch warmer than normal for this time of year, but that's about the only positive. The whole week is a write-off; the wind just won't play nice, and the swell is either too small, too short period, or blown out. We're looking at a gap of over a week with no real recommendations.
After that long, quiet run, things start to get a little more interesting around the 16th. On Wednesday morning, the 16th, a solid 7ft swell from the WSW rolls in, with the energy jumping up to a moderate 418. The wind is offshore and clean from the NW. That's a standout. However, that size is getting into the "experts only" territory. The period is only 7 seconds though, so it's a windswell, not a long groundswell, so it'll be a bit lumpy and less organized than you'd want for a wave that size. It's a heavy, powerful, but messy prospect for the experienced crew only.
The rest of the week is a repeat of the same story – onshore winds and poor surf. We get another spike on the 18th, an 8ft WSW swell with a massive 704 energy reading, but it's pinned down by a strong onshore wind. The quality is just not there. For a spot like this, that setup looks more interesting for kite surfing than paddle surfing.
So, to be honest, there's only one real highlight: the Wednesday morning of the 16th. It's the only time the wind and size align for a possible session, but it's a short-period, expert-only affair. The rest of the window is a long, frustrating wait. Keep your eye on the forecasts, but don't hold your breath.
Rusty.
