The Lowdown

Righto, let’s have a look at what’s cookin’ at Hideaways.

This stretch starts off pretty average to be honest. Monday the 10th has a small 2ft SSW groundswell with a very long 24-second period, and clean offshore SSE winds in the morning. It’s surfable but nothing to write home about – the combined energy is moderate (368). That 24-second period means the sets will be super slow and lined up, typical for a deep ocean groundswell hitting this reef.

Tuesday the 11th morning is where things get interesting. The swell bumps up to a solid 4ft from the SSW, with a 19-second period and clean offshore SE winds. The energy jumps right up (1004). This is the first real standout. For an intermediate-level reef break like Hideaways, that’s a sweet size, and the direction is right on the money – optimum SW. The water temp is about average for the time of year here.

Then it goes flat. Wednesday the 12th through Sunday the 16th is a real dry spell. There’s a tiny bump on the 13th and 14th, but the energy is weak (54-155) and the wave quality is poor. You’re looking at a solid 6-day gap with nothing worth paddling out for.

Now, hang on to your board. The real fireworks start on Tuesday the 18th of August. That morning we get a solid 7ft SSW groundswell with a 19-second period and clean offshore SE winds. The energy is massive (2867) – that’s strong. By the afternoon it’s 6ft and even more energy (3840). This is for experienced surfers only, as it’s over 5ft and pushing expert territory. The consistency at Hideaways is good, so you’ll get plenty of waves.

Wednesday the 19th is the absolute peak. We’re looking at 10ft SSW swell with 18-second period, and the energy is through the roof (5420). Offshore SSE winds in the morning keep it clean. That’s big, powerful reef surfing – experts only. The crowds here are often, so expect plenty of company if you’re game.

Thursday the 20th through Saturday the 22nd keeps the quality high with 8ft to 7ft SSW swell, still very strong energy (3673 down to 1825), and clean conditions each morning. Sunday the 23rd goes flat again, but Monday the 24th brings back 6ft SSW swell with good energy (1960) and offshore SE winds.

So the true standouts are Tuesday the 18th and Wednesday the 19th of August – big, powerful SSW groundswell, clean offshore wind, and Hideaways doing what it does best. Don’t even bother looking at the first week.

Rusty.
