The Lowdown

Alright folks, Rusty here. Let’s be straight up – it’s been a while since we’ve had anything to smile about, and looking at the full picture for Fishermans (Rhiw), this run isn’t going to break that streak. The whole 16-day window is a write-off – literally every session is marked as poor, so there are no good surf options on offer. Best you leave the boards in the car for a fortnight.

The week kicks off with a bit of energy on Tuesday the 8th with a 5ft swell from the west, but it’s got a short period of only 5 seconds, a strong 19 mph cross wind, and the combined swell energy is a moderate 106. Doesn’t matter though – it’s messy and lumpy. Wednesday the 9th and Thursday the 10th offer nothing but onshore junk; Thursday afternoon has a bump to 6ft swell and combined energy jumping to 293, but with a 28 mph southerly slamming straight onshore and that same short period, it’s all chop and no shape – more for kite surfing than a proper paddle session.

From Friday the 11th through the second week, it’s tiny surf with heights dropping below 3ft. Periods hang around the 4 to 8 second mark, meaning no real push. A few mornings show clean conditions with a cross-off wind, but with swell heights at 2ft or less, there’s simply nothing to ride. Even the long period around 11-16 seconds that pops up on the 19th and 20th of September only generates tiny 0.3ft waves – enough for a sea breeze, not a surf. The blank run continues right through to the end on Wednesday the 23rd.

Unless the forecasts change, and they can, don’t hold your breath. When the water temp is sitting at 63° – a touch warmer than normal for the time of year – you know summer’s hanging on without any groundswell to show for it. Sometimes it’s just like that around here.

Rusty.

A general guide to surfing at Fishermans (Rhiw) can be found by selecting the local surf guide option on the grey menu.

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.
