The Lowdown
G’day, Rusty here, and I’ve got to be straight with you – the next two weeks at Inside Reef (Hikkaduwa) are gonna be a battle with the wind more than the waves. The water’s sitting at a warm 83°, which is about average for this time of year, so at least you won’t need a wetsuit.
The problem is the whole run-up is stuffed with risk tstorms and moderate to fresh breezes mostly out of the W or WSW. That means cross-on or onshore wind just about every day, which is going to mess up the face of those long-period SSW groundswells. There’s some serious energy in the water early on – like Tuesday the 1st of September’s 7 ft SSW swell coming in at a 16-second period with a combined swell energy of 2366. That’s a solid, powerful groundswell, but it’s being blown to bits by a 16 mph cross-on wind. It’s just ugly out there. Wednesday morning drops to 5 ft on the same SSW direction, still with that long 15-second period, and the wind turns onshore. The ratings are flat zero for most of the first week, with a couple of “marginal” tags on Wednesday afternoon and Thursday afternoon – but honestly, with onshore wind and risk tstorms, those are not worth paddling out for.
The swell slowly backs off through the first week, dropping to 4 ft by Saturday the 5th, and the wind stays onshore. It’s a long stretch of poor conditions. The second week sees a pulse come back – Saturday the 12th of September shows 6 ft SSW at 17 seconds, combined energy 2273, but it’s still onshore or cross-on. For an advanced reef break like this, the setup actually looks more interesting for kite surfing than paddle surfing, given the wind strength and direction.
There’s not a single standout in this 16-day window. The forecast confidence is high because it’s near-term, but the quality just isn’t there. If you’re desperate, the cleanest window might be the odd onshore morning where the wind is lighter, like Friday the 4th’s morning with 5 ft S swell and gentle 9 mph wind – but that’s a stretch. I wouldn’t bother. It’s a blank run, and for this area, that’s not unusual when the monsoon pattern locks in.
Stay patient, this stretch will pass.
