The Lowdown
Alright, let’s get into it. We’ve got a solid run of swell heading our way.
The Mentawi Islands are firing up. Hideaways is the standout here, and it’s looking prime. We’re starting off Wednesday the 2nd with a clean 6ft on the face from the SW, a solid 16-second period. That’s proper groundswell with plenty of grunt. The water is sitting at 85°, which is bang on average for this time of year.
Thursday morning the 3rd sees the swell drop slightly to 5ft, but the wind turns offshore from the SE, making for clean, lined-up sets. That 14-second period keeps things punchy. The combined energy is still strong, clocking in at 928, so there’s plenty of push.
Friday the 4th is a bit smaller, around 4ft, but still clean with offshore winds and that 13-second period. It’s a good option, but not the best of the run.
Saturday the 5th is a real highlight. 4ft from the SSW, a 17-second period, and offshore winds. This is that long-period groundswell that Hideaways loves. The energy is moderate to strong at 958. Expect long, clean walls.
Sunday the 6th keeps it going with 5ft and 16-second swell, still offshore. The wind picks up a little to 12 mph, but it’s still clean. Energy is high at 1029.
Now, the real standouts start rolling in. Monday the 7th is good, but Tuesday the 8th is next-level. We’re looking at 4ft to 4ft, but with a 19-second period Tuesday morning and 18-second period Tuesday afternoon. That’s a very long period groundswell. The energy readings are massive - 1101 and 1318. This is the kind of swell that wraps perfectly around the reef. Light winds too.
Wednesday the 9th and Thursday the 10th keep things firing in the 5ft to 5ft range, with 15 to 16-second periods. Offshore winds hold.
But then we get to Friday the 11th. This is a big one for experienced surfers. 6ft from the SSW, 15-second period, but the wind is light and cross-off. The energy reading is 1463. This is powerful, clean, and hollow. It’s still a reef break, so surfers need to know what they’re doing.
Saturday the 12th has a glassy, clean morning with 4ft and 14-second period, but the afternoon is a true gem. 5ft from the SW, a 19-second period, glassy conditions. The energy is 2254, which is very strong. This is one of the best sessions of the whole outlook.
Sunday the 13th and Monday the 14th are both excellent. Sunday has 6ft to 7ft from the SW, 17-second period, and clean offshore winds. Energy readings are 2396 and 2347. This is big, powerful surf. Only for experienced surfers. Monday the 14th sees 5ft to 7ft, glassy on the afternoon. Energy at 2459. Again, properly strong.
Tuesday the 15th starts with a glassy 7ft SSW swell at 15 seconds, and energy at 1712. The morning is a standout - calm, clean, and heavy. The afternoon gets a bit cross and lumpy.
The final few days, from Wednesday the 16th to Thursday the 17th, settle down a bit. Swell drops to 4ft to 6ft, periods around 13 to 14 seconds. Still clean, with some glassy moments on the 17th, but the energy drops to the 680 to 1257 range. Fun waves to finish the run.
Hideaways is consistent, exposed to the SW, and gets the optimum swell direction. Crowds are likely here, as it’s a well-known spot. But with this level of quality and consistency over two weeks, it’s worth it.
Best on offer is Saturday afternoon the 12th and Sunday the 13th. The combination of big energy, long period, and clean, glassy or offshore wind is hard to beat.
