The Lowdown
Alright folks, Rusty here. Gotta be straight with you – looking at the 16-day window for Inside Reef (Hikkaduwa), it’s a tough stretch. There’s no run of clean, rideable surf on the cards. The pattern is immediately grim and stays that way.
Right now, we’ve got a solid 8ft SSW groundswell rolling in with a very long 17-second period, and the combined energy is pumping hard (3312). That's a proper amount of juice. But the wind is blowing a steady 12 mph from the West, putting it cross-on and making a mess of things. The water temp is sitting at 83°, which is pretty much bang on average for this time of year, so at least that’s comfortable.
That poor wind and chop hangs around for days. Tuesday the 1st and Wednesday the 2nd still see that strong, long-period SSW swell – 7ft down to 5ft – but it’s constantly blown out by Westerly winds. The energy is still moderate to strong (2362 down to 1015), but the conditions are just poor.
Honestly, there is no standout session here. The best you could even call a maybe is Wednesday afternoon, the 2nd of September. The swell drops to 6ft from the SSW with a 15-second period (1370 energy), and although the wind is onshore, the report calls it “marginal” rather than full-on poor. Even that’s a big maybe.
From there, it’s a long, flat spell. By the 4th and 5th, the swell is down to 4ft to 5ft, the period is dropping fast, energy is weak to moderate (612 to 476), and it’s still choppy. From the 6th of September onwards, we’re looking at a solid gap of days with barely 3ft of swell and nothing but poor conditions. The energy levels dip well below 500. There’s hardly a ripple worth paddling for.
It’s a desert. Nothing to get excited about for the next two weeks at this break. The combo of persistent Westerly winds and the swell direction being SSW – which isn’t the optimum SW the reef likes – just doesn’t click. The forecast might change, but as it sits, save your energy.
Rusty.
