The Lowdown
Alright, mates, Rusty here. Let’s get straight into it. The next couple of weeks are looking like a slow grind with a few windows of real promise. The overall pattern is a pulse of mid-period SW swell, but the wind is the main player here. We're looking at a period where the mornings are often a bit cross, but the afternoons clean up nicely with that cross-off flow. There's a standout stretch in the middle of the run that you'll want to keep an eye on.
The first few days are pretty ordinary. Monday and Tuesday morning are a bit of a write-off with that cross-shore breeze messing up the surface, and the swell is just average. But Tuesday afternoon things start to wake up. The swell pushes to about 5ft from the SW with a solid 16-second period, and the wind swings to a light cross-off. The energy reading jumps to 2443, which is moderate, and the tide looks better. That's a decent session to get the rust off.
Then we get to the main event. Wednesday the 19th is your standout. The swell is up to 8ft in the morning and building to 8ft by the afternoon, coming from the SW with a long 18-second period. You're looking at a strong energy reading of 3611 in the morning, jumping to 4080 by the afternoon. That's a lot of water moving. The afternoon is clean with a gentle cross-off breeze. This is the pick of the week for experienced surfers. This is a reef break, so it handles that long-period energy well, but that size will be pushing it for anyone not comfortable in solid waves. It's an advanced wave, so be on your game.
The rest of the week stays rideable but drops off a notch. Thursday and Friday are still in the 6ft+ range, but the energy settles back into the 3000s and 2000s. The winds are a bit stronger, but still cross-off and clean. You’ll find consistent, if not spectacular, waves. The long period means the sets will be a bit more spaced out, making the paddle out easier, but it can also make the waves jack up faster. It's a good run of waves, just not at the level of that Wednesday peak.
The following week is a quieter, more inconsistent affair. The swell hangs around the 5ft to 6ft mark, but the energy drops back into the 1000s and occasionally the 2000s. The winds stay in that cross-off pattern, so the surface will be clean, but it'll be more of a grovel. The standout in this window is Monday the 24th with a 7ft SW swell and a 17-second period, but it’s not quite as powerful as the previous week. By the end of the month, into the 30th and 31st, we're down to 5ft to 5ft waves. The energy is weak, and the surf is pretty lackluster. The morning of the 30th has a cross-chop to deal with, so the afternoons will be the better bet.
So, if you’re looking for the best surf, circle Wednesday the 19th. That’s the one. The following Monday the 24th is your next-best bet, but it’s a promise, not a guarantee, being that far out. Otherwise, you’re on a slow taper to smaller and less energetic conditions. Water temp is sitting at 80°F, which is about normal for this time of year, so a boardies and a rashie will do you right.
Rusty.
