The Lowdown
Right then, let's have a look at what's on the cards for the next couple of weeks. I'll be honest with you, it's a bit of a flat spell to kick things off, but there's a little something brewing way out in the long range.
So, the water's sitting at about 62°F, which is a touch warmer than we'd normally expect for this time of year. Not a big deal, but worth noting.
The first proper surfable day isn't until the 16th of August. That's a solid week of near-nothing before we get any kind of pulse. The 16th of August morning sees a cross-shore breeze from the WNW at 9 mph, with a WSW swell pushing 6 ft and a period of 6 seconds. The combined energy will be moderate at 197. It's not perfect, but it's the most we've seen in a while. The afternoon picks up a bit more energy, hitting 253 on the combined scale, but the wind shifts a touch cross-onshore. Still, it's the best looking window in the whole 16 days.
Later on, the 17th of August Monday morning cleans right up with a cross-offshore wind from the NW at 12 mph, but the swell drops right back down to 2 ft. Clean, but small.
To be perfectly straight with you, there's nothing here that screams "go out and score." The one standout is the 16th of August, especially the morning, at Fishermans (Rhiw). It's a reef break that's fairly consistent, and the swell direction is a solid SW. The wind is cross-shore, which is ok, but the swell period is a bit short, so don't expect anything too pushy. It's a beginner spot anyway, so that size and chop will be a bit of a handful for the less experienced. The afternoon has a bit more energy, but the wind is a bit worse.
The rest of the forecast is honestly just a lot of poor surf conditions and onshore winds. The 14th of August Friday morning has a bit of a pulse with a 3 ft SW swell, but it's a light cross-onshore and the energy is still low. It's not really worth getting excited about.
So, for the wise heads, that 16th of August morning is your best bet. It's a long way out, so treat it as a promising outlook, not a guarantee. For the rest of us, it's a week of kicking back and watching the forecast.
