The Lowdown
Alright, this is Rusty. Let's get into it.
The surf is looking a bit finicky for Buffalo Bay Wildside over the next 16 days. We’ve got a decent window of opportunity, but also some solid gaps. The real standout is a morning session on Thursday the 13th of August, with a couple of other promising windows.
The first real action is on Tuesday the 11th of August. It’s nothing special, a 7ft swell from the SSW with a 13-second period, but the wind is a cross-off at 16 mph. The combined wave energy is running at 2069 (moderate energy), so there’s push, but it’s only just surfable. The afternoon goes a bit bigger at 8ft, but the period drops to 8 seconds with an 19 mph cross-off, making it a bit of a mess.
Wednesday the 12th of August sees the swell size drop a touch, 5ft in the morning, but the period jumps to a very long 20 seconds from the SSW. That’s proper groundswell energy, coming in at 2634 (moderate energy), but with a 12 mph cross-off, it’s not firing on all cylinders. The afternoon is similar.
Now, Thursday the 13th of August. This is our best day. The morning session is a standout. We’ve got a 5ft swell from the SSW with a 19-second period, which is a long-period groundswell. The wind is a clean offshore from the NE at 12 mph. The combined energy is a solid 3644 (moderate to strong energy). This is the one to aim for. The afternoon stays clean but the wind goes cross-off, and the swell bumps to 6ft, but it’s not as good.
Friday the 14th of August is another good call. The morning is a 5ft swell from the SW, 16-second period, and the wind is a light cross-off from the N at 3 mph. The combined energy is 1619 (moderate energy). It’s clean, with a slight air. The afternoon drops to 4ft with a 15-second period and a light cross-shore, so it’s fun but smaller.
Saturday the 15th of August starts with a small onshore wind and a 4ft swell, but the afternoon cleans up with a 4ft swell from the SW and a 13-second period under a light cross-off breeze. It’s small but clean.
Then we hit a dry spell. Sunday the 16th of August and Monday the 17th are poor, with small, weak swell and cross-onshore winds. Tuesday the 18th of August is a write-off with a strong onshore 19 mph wind, and though the swell hits 10ft on the afternoon, it’s too big for this break. Wednesday the 19th of August is back to clean but marginal.
Thursday the 20th of August has a morning to watch. The wind is a clean offshore from the ENE at 6 mph, with a 8ft swell from the E. The period is a short 7 seconds, so it’s a bit bumpy, but the energy is 1101 (moderate). The afternoon is 10ft, which is too big. Friday the 21st of August and Saturday the 22nd are mostly marginal.
Sunday the 23rd of August is a write-off with strong onshore winds. But then, Monday the 24th of August brings a glassy morning session. The wind is completely calm, with a 5ft swell from the SW at 13 seconds. The energy is 887 (moderate). It’s clean and glassy. The afternoon is less inspiring. After that, the forecast drops away into Tuesday the 25th and Wednesday the 26th of August with very small, onshore junk.
The water temperature here is about average for the time of year.
So, your best bet is the morning of Thursday the 13th of August. The offshore wind and long-period groundswell will give the best shape. The morning of Friday the 14th and the glassy morning of Monday the 24th of August are also solid options.
Rusty.
