The Lowdown

Alright folks, Rusty here with a look at what we’ve got coming down the pipe.

We’re starting off with some fun, clean surf straight out of the gate. Bali Bay (Glen Reef) is the only spot on the menu for this forecast period, so we’re locked in here. Water temps are sitting at 57°, which is a bit colder than normal for this time of year, so you might want an extra layer.

Sunday the 2nd morning is a solid kick-off. We’ve got a 4ft swell coming from the WSW with a 13-second period, and the wind is a gentle cross-off breeze keeping things clean. The combined energy is a moderate 571, so there’s enough push for a good session.

Monday the 3rd is where it gets really good. The morning is glassy with a 5ft SW swell and a 13-second period. The energy jumps up to 865. This is the standout window – clean, well-shaped waves that are going to be a pleasure to surf. Keep in mind the crowds here are possible, so get in early.

After that, Tuesday the 4th and Wednesday the 5th are a bit messy with cross-shore winds and lower quality, but things take a serious turn on Thursday the 6th. The swell pumps up to 10ft from the SW with a 13-second period, and the wind is a clean cross-off. Energy is a massive 3253. This is a strong, powerful swell – definitely for experienced surfers only, as it’s over 8ft.

Friday the 7th morning holds similar energy (3446) with a 10ft SW swell and 14-second period, still with a clean wind. But the afternoon on Friday turns choppy with cross-onshore winds, so the morning is the pick.

We hit a wall on Saturday the 8th. The swell absolutely explodes – 23ft to 25ft from the SW with energy readings of 19561 and 23304. That is way, *way* too big for this break. It’s a beach-and-reef setup that would be more interesting for kite surfing than paddling.

That huge energy drops back on Sunday the 9th, but 15ft is still too big for a comfortable paddle. Things finally settle down by Monday the 10th with a much more manageable 6ft swell from the SSE and a clean cross-off wind.

The second week sees a mix. Tuesday the 11th morning has a clean 5ft swell (SW, 10-second period) and good wind. Friday the 14th is a real highlight – both morning and afternoon see clean conditions with a 7ft WSW swell and a long 15-second period. The energy is strong at 2562, and the offshore wind in the afternoon is a beauty. Monday the 17th morning also offers a glassy 8ft WSW swell.

Keep an eye on Saturday the 15th afternoon – that’s a 6ft swell with a very long 20-second period, giving a massive 3799 energy reading, but the wind is a light cross-onshore. That long period means the reef will handle it well, but the chop might be a nuisance.

Overall, the standout is Monday the 3rd morning for its glassy, clean, and fun waves. For the big dogs, Thursday the 6th through Friday the 7th morning offer serious, clean power but are expert-only.

Rusty.
