Alright, let's get into it. This is Rusty, checkin' in with the local scoop.
We gotta be patient for the first few days, but there's a solid pulse of energy coming later for the crew that can handle it. The main event is a proper swell train that arrives in the second week, but it's gonna be a big one, so it's not for everyone.
Right now, Friday the 10th is a bit of a tease. Narrabeen-Alley Rights is seeing some inconsistent SE swell pushing about 6ft with a 10-second period, but the wind is light and cross, so it's a bit messy. The wave energy is moderate (566), but it's a marginal call. The afternoon glass-off is a better bet as the wind drops to glassy, and the swell drops a touch to 5ft, but the score is still low. You'll find a few if you're keen, but it's not the highlight of the run.
Saturday the 11th morning is a better call. Clean lines with a light offshore from the NW, and the swell has dropped to 3ft from the ESE, period stretching to 12 seconds. That's a longer period groundswell, which will give the waves more shape and push, making it a cruisy session on the beach/sandbar set-up. The energy is moderate (407). It's a nice morning, but a touch small for the more advanced crew.
After that, it goes flat. Very flat. From Sunday the 12th right through to Wednesday the 15th, we're talkin' barely a ripple. The energy numbers drop right off (104, 60, 7, then down to zero). It's a real dry spell, so don't bother paddling out.
Now, let's talk about the real deal. Thursday the 16th. The swell is back, and it's not messing around. We're looking at a 12ft SSE swell on Thursday morning, jumping to 15ft in the afternoon. The wave energy is strong, hitting 2091 in the morning and 4069 in the arvo. This is a big, powerful, average period swell (9-10 seconds). The wind is moderate cross to cross-on, so it's gonna be lumpy and choppy. The forecast notes say it's too big for this break. Honest truth: this is expert-only territory. If you're not an absolute charger, stay on the sand. The swell is going to be intense and unruly.
The peak of the event hits on Friday the 17th, with a massive 18ft swell from the SE and SSE, with a 12-second period. The wave energy is extreme (8866). The wind is a problem, though, pumping onshore at 15 mph on the afternoon session. It's a beast, but it's a messy beast. Only the most experienced, and maybe the biggest kites, are going to get a look in on this one. The beach setup is going to be a washing machine. For the average surfer, this is a pass.
The swell sticks around through the weekend, but it's still too big. Saturday the 18th morning sees light cross-off winds and an 18ft SSE groundswell (energy 8418), making it cleaner but still huge. By Sunday the 19th afternoon, the swell has dropped to 8ft from the SE, and the wind is a clean cross-off from the NNE. The energy is still strong at 1358, and the forecast calls it excellent for experienced surfers. This is the standout window for the more advanced crew who can handle solid, clean waves.
Heading into the following week, things settle down nicely. Monday the 20th morning is the pick for the masses. The swell is a manageable 6ft from the SE, with a 10-second period, and it's glassy with a clean offshore breeze from the NW. The energy is moderate (676). It's a return to form, with clean, fun waves for everyone.
After that, the swell fades out through the rest of the week, getting smaller and smaller until we're back to flat by the weekend. So, the big story is the monster swell from the 16th to the 19th, which is a serious test for the big-wave chargers. For the average punter, Monday the 20th morning is your best bet for a clean, fun session.
