The Lowdown
Alright amigos, Rusty here. Let’s talk about Hideaways.
We’re starting Sunday morning, 6th September, with a long-period SSW groundswell. First light shows 5ft, 16-second swell out of the SSW with a clean offshore breeze. The energy is at 1016 – that’s moderate. The morning is the pick. By Sunday arvo it drops to 3ft and the wind gets a little sketchy.
Monday morning, 7th, is very similar: 4ft, 14 seconds, still offshore. Clean. The arvo goes cross-off, so morning is the call.
Tuesday morning, 8th, is a highlight. The swell is 4ft but the period stretches to 18 seconds, and energy climbs to 1279. Offshore and glassy. The arvo builds to 5ft, 17 seconds, energy at 1432 – that’s getting chunky for beginners.
Wednesday the 9th is flat. No swell.
Thursday morning, 10th, picks up again with a solid 5ft, 16-second SSW groundswell, offshore, and 1354 energy. A powerful morning. Friday the 11th keeps it pumping at 6ft, 15 seconds, and 1602 energy – again offshore and clean.
Saturday the 12th is a big day. Saturday morning shows 5ft but the period is 19 seconds, energy 2097, and offshore wind. The arvo jumps to 6ft, 19 seconds, and 3301 energy – very strong. That’s expert country.
The whole stretch from Sunday 13th to Tuesday 15th stays solid, with 6ft to 7ft SSW groundswell, periods of 14 to 17 seconds, and clean to offshore winds. Energy is in the thousands. By Wednesday 16th, the wind turns cross-on, and the quality drops.
Then we get a big reset. Friday 18th and Saturday 19th are the next standouts. Friday morning has 8ft, 18-second SSW groundswell with offshore wind and 3129 energy – that’s a serious wave for experts. Saturday morning is 8ft, 16 seconds, still offshore, with 2648 energy.
We trail off into Sunday 20th and Monday 21st with no surf.
The standout here is Hideaways reef. It’s consistent and gets the optimal SW direction. Crowds are often here. Water temp is about average for the time of year. The best sessions are the mornings of Tuesday 8th, Thursday 10th, and Friday 18th and Saturday 19th – those have the cleanest offshore winds. Once swell hits 7ft or more, it’s only for experts. So keep that in mind.
Rusty.
