The Lowdown
Alright, folks. Rusty here. Let’s get into it.
We’ve got a solid run of swell on the way for the next couple of weeks, all focused on one spot. The first few days are going to be a bit of a mixed bag on the wind front, but the size and energy are there to keep things interesting.
The standout window is shaping up to be the morning of Wednesday, August 12th. Sunset Beach Geraldron is looking pumping with a solid 8ft SW groundswell. The period is a very long 16 seconds, which means proper lines of energy pushing through. The wind is offshore from the east at 12 mph, and that’s going to keep the faces clean. The combined swell energy is pumping at a strong 3499. This is a setup for the experienced crew only – that size on a beach and reef setup with that much push is not for the faint of heart. For the beginners, this is too much wave.
The water temperature is about average for this time of year, nothing crazy to report.
Moving into Thursday, August 13th, and Friday, August 14th, the swell stays in the 8ft to 8ft range from the SW, still with those long 15-16 second periods. The winds will be more cross-offshore, which is still clean, but not quite as glassy as Wednesday morning. The energy is still strong, hanging around the 2500-3500 mark. Still a spot for experienced surfers only.
The weekend sees a bit of a drop. Saturday, August 15th, is smaller at 6ft, but still a decent SW groundswell. The wind is cross-offshore again, so it’ll be ridable. The energy drops to moderate (1505). By Sunday, August 16th, the morning swell dips to 4ft with a long period, but the wind is a cross-offshore 16 mph, which is a bit blustery. The afternoon picks up to 6ft, but the wind goes cross-shore, creating a little chop.
The following week gets interesting again. Tuesday, August 18th, is another cracker. The morning session has an 8ft WSW swell, a very long 16-second period, and a light offshore breeze from the ENE. The energy is huge at 3832. This is a serious call for the experienced crew.
Beware of Wednesday, August 19th afternoon. The swell jumps to a massive 12ft from the SW, with a combined energy of 10910. That’s some serious power. Even with the wind being gentle cross-onshore, that level of swell is going to be too big for this break, and only for the most expert of experts.
The run continues into the third week. Saturday, August 22nd morning, we see another 12ft SW groundswell with a very long 20-second period. That’s a proper groundswell, and even with a clean cross-offshore wind, it’s a beast for experts only. The energy is off the charts at 8723.
The last few days of the forecast, from August 24th onwards, are a write-off. The wind turns onshore and strong, the swell drops, and the conditions become poor. The morning of Wednesday, August 26th offers a little hope with a 4ft SW swell and offshore wind, but the energy is weak (533). It’s better than nothing, but it’s a far cry from the big stuff earlier in the month.
If you are an expert, mark your calendar for Wednesday morning, August 12th, and Tuesday morning, August 18th. Those are the best of the best on offer.
Rusty.
