The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the Mentawi Islands.
We’ve got a solid run of surf coming up, starting this Thursday. The water’s sitting at a warm 85.3°, which is pretty average for this time of year, so no surprises there.
The standout period kicks off this Thursday (27th August) afternoon. Hideaways (Mentawi Islands) is the only spot firing, and it’s looking proper. A strong SSW groundswell at 6.9ft is rolling in with a very long 18-second period, packing some serious punch with a combined energy of 2734. That’s a full-on, powerful swell. The wind is light and cross-offshore, so the surface will be clean and lined up. This is serious intermediate-to-expert territory – too big for beginners. Friday morning (28th) is the real gem, with a 6.9ft SSW swell, a 16-second period (2075 energy), and clean SE offshore winds. That’s the pick of the bunch: offshore, clean, and solid. The swell gradually drops through Saturday and Sunday, but it stays very good with clean conditions and light breezes.
We get another punchy pulse from Monday (31st) into Tuesday (1st September), with the swell size picking back up to 7.9ft on Tuesday morning, coming from the SW with a 17-second period (3082 energy). That's the biggest, most energetic swell of the run. Again, the wind is gentle offshore, so it’ll be clean and perfect for experienced surfers. This quality holds through Wednesday (2nd September) with 6.2ft to 5.9ft surf and clean offshore winds.
Then we hit a flat spot: Thursday and Friday (4th-5th) have no rideable swell – complete doldrums. The run picks back up Saturday (5th) afternoon with a small 3ft SSW swell and picks back up again into a more consistent 4.9ft to 5.2ft run from the 6th to the 7th. The forecast towards the 11th of September shows another strong SSW swell at 6.9ft with a 16-second period and clean offshore winds. That one’s a long way out, so less certain, but it looks promising.
Overall, this is a classic Mentawi run: powerful groundswells, mostly clean wind. The absolute best on offer is Friday morning (28th Aug) for the combination of size, period, and perfect offshore wind. Tuesday morning (1st Sep) is a close second for the raw power and energy. Expect crowds at Hideaways, as it’s a well-known, consistent reef break – it gets busy.
