The Lowdown
Hey, Rusty here. Gotta say, looking at the next 16 days for Merewether - Ladies, it's a mixed bag. The water temp is sitting at 65°, pretty much normal for this time of year, no surprises there.
Right off the bat, Saturday the 12th is a no-go. We got a 3ft SSE swell with a cross-on ENE breeze at 12 mph and 468 units of energy – it's just choppy junk. Not worth paddling out for.
But Sunday the 13th morning is where it gets interesting. A clean 3ft S swell, period of 9 seconds, with a light NNE cross-off breeze at 6 mph. Energy drops to 201, but that wind is making it tidy. That's your first real window – small but workable, and clean.
Monday the 14th morning is surfable but ordinary. You've got a 2ft S swell with a 12-second period (longer gaps between sets) and a light N wind. It's clean but pretty weak at 158 energy.
Then we hit a real rough patch. From Tuesday the 15th right through to Thursday the 17th, it's all poor surf. The swell jumps but so does the wind. On Wednesday the 16th, we're looking at a massive 10ft to 12ft S swell with 1676 to 2230 energy, but it's blowing 25 mph SSW cross-on. Messy, dangerous, and way too big for anyone but experts. Thursday the 17th is much the same – 8ft to 10ft S swell, strong cross-onshore winds. Leave it.
Now, Friday the 18th morning is a slice of hope. A clean 4ft S swell, 8-second period, with a light offshore NW wind at 6 mph. Energy is 314. It's not huge, but that offshore breeze will make it glassy and fun.
But the real standout? That's Saturday the 19th morning. This is the best on offer. We've got a 4ft ESE groundswell, period of 11 seconds, pushing 580 energy. And the wind is a light offshore WNW at 9 mph. That's clean, lined-up waves with some push. The swell direction (ESE) is a perfect match for the optimum at this break. Brilliant morning.
After that, Sunday the 20th and Monday the 21st are small and ordinary again. Then we roll into another flat spell with only tiny, weak swells through to the end of the 16 days – nothing worth getting excited about.
So, bottom line: Sunday the 13th morning for a small clean wave, but Saturday the 19th morning is your standout. Get on it.
