The Lowdown
Alright, Rusty here, let’s get into it.
First up, we’ve got Hideaways in the Mentawi Islands. The water is sitting at a toasty 86°, which is a touch warmer than normal for this time of year, so it’s already feeling pretty special.
The next few days are pretty lackluster to be honest. Wednesday the 22nd has some clean little 4ft waves from the SSW with a 13-second period, but the energy is weak (378) and the conditions are only marginal. From Thursday the 23rd right through to Monday the 27th morning, we’re looking at mostly tiny surf, mostly under 2ft, with moderate offshore winds. It’s surfable but very ordinary. There’s a big gap of mediocre conditions here. Monday the 27th looks like a turning point.
Monday the 27th onwards, things start to clean up properly. Light offshore breezes and clean 2ft waves from the SSW with a long 17-second period, carrying moderate energy (294). The consistency is there. Tuesday the 28th afternoon sees glassy conditions with 2ft waves, and the energy is building.
Now, the real standout window kicks off on Wednesday the 29th. By the afternoon, we’ve got 2ft surf but the period jumps to a very long 21 seconds and the energy is strong (569). That’s a proper groundswell. Thursday the 30th is the best on offer: clean conditions, light offshore winds, 4ft to 4ft waves from the SSW, with a 19 and 18-second period, and the energy is very strong (1123 to 1204). This is the kind of day you book off work. The swell direction is right on the money for this reef break.
Friday the 31st keeps it pumping with glassy conditions and up to 5ft waves. Saturday the 1st of August morning is glassy with 5ft waves and very strong energy (1155), but the afternoon turns a bit cross-onshore, so the morning is the pick. Sunday the 2nd and Monday the 3rd see the swell push up over 5ft to 6ft with onshore winds, so the quality drops into marginal territory. But then Monday afternoon glass off again: 6ft, 16-second period, and excellent conditions. That’s the second standout for experienced surfers.
Into the second week, Tuesday the 4th and Wednesday the 5th are glassy with 4ft to 5ft waves, and the energy remains strong. Thursday the 6th of August is a standout for the experts: 6ft to 7ft from the SSW, glassy, 17-second period, and massive energy (2048 to 2173). That’s big, clean, and powerful. Only for experienced surfers, and it could be a bit straight for the beach but at a reef like Hideaways, it’ll be firing.
Crowds are often an issue here, so if you’re going for the standouts, expect company.
Rusty.
