The Lowdown

Alright, Rusty here again. Let's break down this 16-day stretch for the coast. To be straight with you, it's a tough outlook. We're looking at a long stretch of small, weak surf, with only a few brief windows of clean, rideable waves. The real size shows up late in the month, but the wind will be against us.

First up, the water is running a bit colder than normal, at 62°, which is a couple of degrees cooler than the long-term average. You'll want the full suit.

The opening days are a complete bust. Sunday the 16th is a right-off with onshore winds and a weak 5ft SE swell. The energy is weak at 157. Monday the 17th and Tuesday the 18th are better, but that's not saying much. We get some glassy mornings with a small 3ft ESE swell, but the period is short and the energy is weak, down in the 80s and 90s. It's surfable, but you'll be scratching for anything. The afternoons are messy with cross-onshore winds.

Wednesday the 19th is a repeat: a glassy morning with a small 3ft ESE swell, but still weak. The wind goes offshore from the NW on Friday the 21st, which is a good sign, but the swell has dropped to around 3ft and the energy is weak. It stays clean but tiny through the weekend, with the swell fading to almost nothing. By Sunday the 23rd and Monday the 24th, we're in ankle-slashers of 1ft. This creates a solid 10-day gap where the surf is just not worth your time.

The reason for this flat spell is a mix of small, short-period swell and a lot of onshore wind. The only real pulse in the middle of this comes on Wednesday the 26th. The swell kicks up to 6ft from the SSE, and the energy jumps to 516, a moderate pulse. But the wind is cross-onshore and it’s choppy, so the quality will be poor. It's a messy, powerful session, not a clean one. Thursday the 27th has a similar story with a 4ft SSE swell and a longer 11-second period, but the wind is still on it. There's a lot of water moving, but it'll be lumpy and hard work.

The final days of the month are more of the same: small, weak, and junky. There is a little bump from the SSE on the 29th, but the wind is wrong.

So, what's the pick of the litter? Honestly, the best option is the glassy windows on the mornings of the 17th and 18th. The waves are tiny, but the conditions are clean. You might find a few fun ones on the banks at Narrabeen-Alley Rights if you're in the right spot. It’s not a standout, but it's the best of a bad bunch. The bigger swell on the 26th is the only time we see any real size, but the wind ruins the quality. That day is one for the experienced chargers only. For everyone else, this is a week to catch up on other things.

With the onshore winds and small swells, this stretch might actually be better for the kite surfers than us. The swell directions are all over the place, so the banks will be inconsistent. It's a waiting game, for sure. The break is usually pretty consistent, so this kind of blank run is more of an anomaly, and forecasts can change. But right now, it's a lean period.

Rusty.
