Alright folks, Rusty here. Let's cut through the noise and talk about what A-Bay has in store for us.

First off, we're looking at a real slow start. From Friday the 3rd all the way through to Thursday the 10th, the ocean is basically taking a nap. No swell to speak of, with energy readings sitting at zip or next to nothing. Doesn't matter how glassy the wind gets, you can't surf flat water.

We finally see a pulse on Saturday the 11th. Afternoon brings some knee-high lines. It's 0.5m swell from the west at 14 seconds, with energy creeping to 97 (weak). The afternoon goes glassy, so it'll be clean, but it's just "surfable waves." Not worth rushing out for.

Sunday the 12th keeps the 0.5m west swell in the morning, but it's onshore from the WNW. The afternoon glass-off returns, but the energy drops to 56 (weak).

Now, Monday the 13th is where things get real. The afternoon session has 0.6m of west swell with a very long 15-second period, and the energy hits 239 (moderate). It's glassy. That's a proper start. A-Bay is a reef and point break, so that long-period groundswell will wrap in and give you some nice, lined-up waves.

Here's the standout of the whole forecast: Tuesday the 14th afternoon. That's your call. Swell bumps to 0.9m from the west, the period stretches to a long 17 seconds, and the energy is a solid 454 (strong). Wind is glassy. It's gonna be clean, with proper waist-to-chest high sets rolling in. This is the day.

Wednesday the 15th is another banger. The morning is a bit onshore from the WNW, but the afternoon goes dead calm. 0.9m of WNW swell at 16 seconds, with energy at 447 (strong). It's a close second to Tuesday.

Thursday the 16th holds. The morning is glassy with 0.8m from the WNW at 15 seconds, energy at 304 (moderate to strong). The afternoon is dead calm with 0.8m from the west at 15 seconds, energy at 287 (moderate). More clean, fun waves.

The final weekend, the 17th and 18th, the swell fades down to 0.6m and 0.5m, energy dropping back to weak. Still, with glassy afternoons, you'll get some small, clean rollers to finish the run.

So the play is clear: survive the first week, then get after it from the 13th through the 16th. Top of the list is Tuesday the 14th afternoon: 0.9m, west swell, 17 seconds, glassy. A-Bay will have some crowds "sometimes," but that's a price worth paying. The water's running a touch warmer than normal for this time of year at 27°.

Rusty.
