The Lowdown

G'day, Rusty here, and I've got to be straight with you – the next couple of weeks are looking pretty flat and disappointing for us. We're not seeing much in the way of decent surf, and it's gonna be a long wait for anything that's even worth a mention.

Let's start with the good news, such as it is. The only spot that's got any life in this whole 16-day window is Fishermans (Rhiw). It's a reef break, so it needs a bit of size and direction to get going, and it's fairly consistent. The water's sitting at 65°F, which is a good 4°F warmer than usual for this time of year – that's a nice little bonus if you're in the water.

But the problem is, for the first week and a half, we're looking at a total drought. From Sunday the 16th right through to the 27th of August, the swell is tiny, mostly around 0.3 ft to 2 ft, and even when there's a bit of energy mid-week, the wind is howling and ruining any chance of a clean wave. On Wednesday the 19th, we get a jump in combined energy up to 117 (moderate energy), but the swell is a weak 5 ft from the WSW with a short period of 5 seconds, and it's getting smashed by 25 mph onshore winds. That's not surf, that's a washing machine. It's a better setup for kite surfing than paddle surfing.

The first real glimmer of hope doesn't come until Friday the 28th of August. The morning shows a 4 ft SW swell with a period of 6 seconds, and the combined energy climbs to 126 (moderate). The wind is light and cross-offshore, so the conditions are clean. The wave comment says "surfable waves but very ordinary conditions," and it scores a 1 out of 10, so it's not a standout, but it's the only thing on the whole forecast that's even surfable. The afternoon on the 28th gets a bit bigger at 5 ft (161 combined energy), but the wind picks up and the conditions drop off.

After that, it's back to nothing. The 29th and 30th of August have offshore winds but the swell is only 2 ft to 2 ft.

So, to be honest, there's not a single day I'd call a standout. The best on offer is the morning of Friday the 28th of August at Fishermans (Rhiw) – it's your only chance, and it's not going to be epic. The rest of the time, you're better off checking the forecast again in a few days. It's a long, blank run for this area, but it happens.

Rusty.
