The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Gonna be straight with you – the 16-day window is looking pretty grim for a proper paddle. There's a massive gap right off the bat. Nothing worth mentioning from now until the 25th of July with just tiny, weak dribbles and mostly cross-off winds. We're talking clean but flat. It's a tough start.
Then, around the 26th of July, we get a bit of a pulse. The swell bumps up to 3ft early on Sunday the 26th, but it's a short period 6-second windswell from the SW, and the wind is a fresh cross-onshore. It's messy and lumpy. The combined energy only hits 52 (weak), so it's not got any grunt. The afternoon gets a little bigger at 5ft, energy jumps to 115 (moderate), but the period drops to 5 seconds and the wind is still onshore. It's a bit of a washout. Honestly, for a reef break like Fishermans (Rhiw), this setup looks more interesting for a kite surfer than a paddle surfer, given the cross-onshore wind and short-period chop.
The rest of the month is more of the same story. There's a few tiny clean windows on the 30th and 31st of July with light cross-off winds, but the swell is barely 2ft with a period of 4-6 seconds, so the energy is negligible (1 to 29). It's not going to break properly.
Water temp is about average for the time of year, no real anomalies to get excited about. The optimum swell direction for this spot is SW, but even when we get a little bit of that on the 26th, the wind ruins it.
There is no standout session in this entire 16-day outlook. It's a long, flat, and mostly blown-out run. Sometimes that's just how it goes in this area. The first proper glimpse of anything might be a tiny window on the 31st of July, but it's a real long shot. I'd be keeping an eye on the forecasts, because it tends not to stay this poor for long.
Rusty.
