The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cookin’ for Hideaways.
We’ve got a proper run of solid, consistent swell on the way, and the water temp is sitting at 85°F, which is pretty much bang on average for this time of year. The main story is a long, drawn-out pulse of SSW groundswell that’ll keep things interesting for the next couple of weeks.
Monday the 14th gets us started with a clean 7ft SSW swell, period a juicy 16 seconds, and the combined energy is strong at 2007. The wind is cross-off from the south, so the face will be workable, but it’s not glassy perfection. A solid opener.
Tuesday the 15th morning is where we hit a proper standout. The wind shifts to a light offshore from the SE at 9 mph, and we’ve got 6ft of SSW swell with a 15-second period (moderate wave energy at 1550). The conditions are clean, offshore, and the wave quality is top-notch for experienced surfers. This is the session to circle if you want a quiet, high-quality paddle.
The swell dips a touch mid-week, but Saturday the 19th morning is a ripper. It’s glassy—dead calm, with the wind basically non-existent from the SW at 3 mph. The swell jumps back to 7ft, period stretches to a very long 18 seconds, and the combined energy is a proper 2336. This is a serious groundswell; it’ll have plenty of punch and long lulls. For a reef like Hideaways, that’s a dream scenario.
Sunday the 20th morning is another big one: 8ft of SSW swell at 16 seconds, offshore SE wind at 12 mph, and a combined energy reading of 2731. That’s strong, powerful surf. It’s getting up there in size, so this is one for the experienced crew only. The wind is moderate offshore, so the surface will be clean but with a bit of texture.
Towards the end of the run, Sunday the 27th afternoon catches the eye: 8ft of SSW swell, 18-second period, and the combined energy is massive at 4236. That’s a powerful, long-period groundswell. The wind is light from the south, cross-off, so it’ll be clean. This one’s a late blast of energy, promising but less certain this far out.
Monday the 28th carries that energy with 8ft in the morning and glassy conditions in the afternoon with a 7ft SSW swell. Both sessions are excellent for experienced surfers.
The rest of the week shows clean, rideable surf in the 4ft to 6ft range, with offshore or light winds most mornings. The consistency is there, and the crowds are likely at this spot, so get on it early.
Rusty.
