The Lowdown
Imperial Version
Alright folks, Rusty here. Gonna be a tough one for the next couple of weeks, so let's get real.
Look, I'm not gonna sugarcoat it. The next sixteen days are looking pretty flat for Fishermans (Rhiw). There's no real swell on the menu, and what little energy we get is just not enough to do anything with. We're looking at a long stretch of tiny, weak waves that won't even break properly. The first recommendation doesn't come until the 30th of July, and even then it's just small stuff.
For the morning of the 30th, we've got a weak 1 ft swell from the SW, with a short period of 5 seconds. The wind is a cross-off from the NNW at 12 mph, which isn't ideal for cleaning things up. The combined energy is a measly (6), and the report says "poor surf conditions." Honestly, it's a total write-off.
The 31st of July is more of the same. A 2 ft windswell from the W on Friday morning, with a period of 4 seconds. It's a cross-shore wind, and the energy is still only (8). Not a chance.
The first day of August brings a little glimmer, but it's still not enough. Saturday morning has a 1 ft SW swell, period of 5 seconds, with a light cross-off breeze from the NW at 6 mph. The energy is a bit higher at (9), but it's still "poor surf conditions." You'd be scratching for a knee-high ripple.
The 2nd of August is basically flat. The combined energy drops to (4) on Sunday morning with a 0.3 ft swell. The water is about average for the time of year.
We get a slight bump in energy on the 3rd of August with a combined energy of (31), but the swell is still only 1 ft. The period stretches to 9 seconds, which is a bit better, and the wind is offshore from the NNE in the afternoon at 12 mph. The report says "moderate offshore and clean," but with that tiny size, it's a non-starter.
The rest of the run is a flat spell. The 5th of August afternoon has some glassy conditions with a 1.0 ft swell, but the energy is still only (10). By the 11th, it's dead flat with a 0.3 ft swell and zero wind. The 12th of August has a tiny increase to 1 ft, but it's cross-on and the period is only 4 seconds. The 14th of August morning has a 1.0 ft swell, glassy conditions, but the energy is only (3).
There's nothing here to get excited about. The best day on offer is probably the 5th of August afternoon, with tiny swell and glassy conditions, but even then, you're just hoping for a ripple. It's a tough run for Fishermans. Some places just stay flat, and this is one of those times. Forecasts can change, but right now, this is a blank run.
Rusty.

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.
