The Lowdown
Alright folks, Rusty here. Let's have a look at what's comin' our way for the next couple of weeks down at the pier.
The week ahead starts off small and clean but gets a bit messy mid-week before a couple of pulses of bigger swell show up. The water is a touch colder than usual for this time of year at 60°, so you’ll want a decent suit.
Monday morning the 14th is your pick for the first few days. It’s glassy with a light 3 mph SW breeze and a clean 4ft south swell, period of 8 seconds. Combined energy is moderate (325). Not huge but it’s the best on offer early on.
Tuesday the 15th is smaller, with 3ft south swell at 10 seconds. The wind is cross-off in the morning with WSW at 9 mph, keeping it clean, but the size is a bit weak.
Wednesday the 16th sees a bump in energy with 5ft south swell (9 seconds) in the morning, cross-off SW wind at 9 mph, so clean again. The combined energy jumps up to moderate (522). The afternoon gets a bit onshore but the morning is worth a look.
Thursday the 17th is a write-off with strong cross-shore NE winds at 16 mph making a mess of the 5ft swell.
Friday the 18th and Saturday the 19th are also poor with onshore winds and small, weak swell. Not worth paddling out.
Now, Sunday the 20th brings a big pulse of 10ft ENE swell, but that’s just too big for this break – expert only, and even then it’s pushing it. The wind is light and offshore in the afternoon though, so it’ll be clean, but the size is a major caveat. The combined energy is strong (1697).
Monday the 21st is a standout. The morning is glassy with a 7ft ENE swell at 10 seconds. Combined energy is strong (706). This is the best window of the whole outlook. Clean, solid, and well-shaped. This is the one to circle on your calendar.
After that, the surf drops off again through the end of the month. Tuesday the 22nd is small and onshore, Wednesday the 23rd has a 8ft east swell but it’s short period (8 seconds) and onshore, so messy and only for the keen. Thursday the 24th and Friday the 25th are small and poor, and the weekend of the 27th-28th is blown out with onshore wind and rain. There's a small window Tuesday the 29th with 6ft south-southeast swell at 11 seconds and light winds, but it’s marginal.
So, overall, Monday morning the 21st is the clear standout – get in the water early for the best of it.
Rusty.
