The Lowdown
Alright, Rusty here for the Hikkaduwa crew. Let’s break down the next couple of weeks.
Water temp is about 83°F, pretty normal for the season, nothing weird there. But the wind story is the same old tune – westerly winds blowing 12 to 16 mph, mostly cross-onshore or onshore. That’s going to mess up the surface for pretty much the whole run.
We start this Saturday afternoon, August 29th, with a 4ft SSW swell, 13-second period. Combined energy is moderate at 901, but with thunderstorms and cross-onshore wind, it’s a no-go.
Sunday the 30th brings more size. The morning has a 5ft SSW swell with a very long 19-second period, energy jumps to 1756. That’s some proper groundswell, but again, cross-onshore wind and poor conditions. Afternoon it’s 5ft with 18-second period, energy at 2008, but still blown out.
Monday the 31st is the biggest. Swells hit 8ft to 8ft from the SSW, period dropping to 17-18 seconds, and energy readings of 3377 and 3473 – that’s strong energy. But that’s too big for beginners, and with 16 mph cross-onshore wind, the surface is going to be a mess. At that size with that wind, this reef spot is gonna be a kite surfer’s dream, not a paddler’s.
Tuesday the 1st of September sees 7ft dropping to 6ft, period at 16 seconds, and still cross-onshore. No good.
Wednesday the 2nd of September afternoon is the only glimmer. Swell drops to 6ft, 15-second period, energy at 1349. The forecast calls it “marginal.” That’s the best we get, and even then, the wind is cross-onshore making it lumpy. Only a 1 out of 10 chance it lines up.
From Thursday the 3rd all the way to Saturday the 13th of September, it’s a wasteland. Swells shrink to 3ft to 5ft, periods drop to 9-14 seconds, and energy falls from 1231 down to weak readings like 301. Every session is marked poor.
There’s no real standout here. The closest thing to a surfable day is that Wednesday afternoon, and it’s a big maybe. This is one of those dry spells for the area. Keep your gear ready and hope the wind shifts.
Rusty.
