The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Fishermans (Rhiw).
To be straight with you, the next sixteen days are a real struggle. We’ve got a long, quiet stretch ahead. The swell is tiny and the conditions are messy for the most part. There’s no standout session, and honestly, no surf worth paddling out for. The first few days are flat, and we’ve got a gap of over a week with nothing but knee-high slop and poor surf. It’s one of those blank runs that’s pretty normal for the area when the swell windows don’t align. Don’t lose hope, though – forecasts can change.
The only day that even gets a pulse is Wednesday the 5th of August. On the morning, we see a bump in swell to 4 ft from the SW with a period of 7 seconds. The combined energy hits 102 (moderate wave energy), but the wind is a cross-onshore at 16 mph, which puts a chop on it. That afternoon, it drops to 3 ft with onshore wind – still poor. It’s a beach-and-reef setup, so with that wind and weak, short-period swell, it’s more interesting for kite surfing than paddle surfing.
The rest of the window is a washout. A few mornings see glassy conditions, like Monday the 3rd of August afternoon with glassy wind and 1 ft, but it’s simply too small. Even the clean offshore winds on Sunday the 2nd of August morning and afternoon can’t do anything with the 0.3 ft swell. The water temp is around 62° with a 1° anomaly – about average for the time of year.
Look, I’m not one to sugarcoat it: there’s nothing good here. The best advice is to wait for a proper SW groundswell and a northerly offshore wind. Until then, keep the board in the shed.
Rusty.
