The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this forecast for Fishermans (Rhiw) is a tough one to write. Over the next 16 days, there’s just not a single decent wave on offer. The swell is tiny, the wind is mostly wrong, and the whole period is a write-off for surf. We’ve got a long gap of nothing worthwhile from now right through to the end of the forecast.
Right from the start on Monday 27 July, it’s a mess. The wind is onshore from the SW at 16 mph, and the swell is a weak 2 ft from the SW with a short period of 4 seconds. The combined energy is a paltry 18, which is nothing. It’s poor surf conditions, plain and simple. The water temperature is 63°, which is a touch warmer than normal for this time of year, but that’s about the only thing going for it.
Tuesday 28 July and Wednesday 29 July are more of the same – onshore wind, tiny swell, no energy. The water temp anomaly isn’t even recorded for the rest of the period, so we’re flying blind on that.
Thursday 30 July through to Friday 7 August is a depressing run of tiny, weak swells, with heights barely breaking 2 ft. The wind does occasionally go light or cross-off, like on the afternoon of 30 July when it’s a light cross-shore, or on Sunday 2 August when it’s cross-off from the NNW and clean. But the swell is so small – 0.7 ft at best – that you’d be floating over a ripple. The combined energy readings are in the single digits or low teens. It’s not surfable.
We do see a spike in size on Saturday 8 August, with a 6 ft swell from the W, period 6 seconds, and combined energy hits 184. But the wind is a cross-onshore from the SSE at 12 mph, turning into a fresh breeze by the afternoon, making it choppy and lumpy. The wave quality is rated as poor. Sunday 9 August pushes up to 6 ft from the WNW and energy of 248, but the wind is howling onshore from the SW at 22-25 mph. That’s blown-out, messy, and dangerous. At that size and those winds, this beach-and-reef setup looks more interesting for kite surfing than paddle surfing.
The final days from 10 August to 11 August drop back to nothing – tiny swells, strong winds, and no clean conditions.
The only real standout, if you can call it that, is the morning of Thursday 6 August. The wind is glassy from the NE, and the surf is clean. But the swell is just 1.0 ft from the SW with a period of 7 seconds and energy of only 9. You’d be bobbing around on a lake. Not worth the drive.
So, there you have it. A blank run for the whole 16 days. It’s one of those periods where the forecasts can change, but as it stands, there’s nothing to recommend. Hang up the board for a bit.
Rusty.
