The Lowdown
Alright, let’s break it down in feet and miles per hour. Rusty here, and it’s a grim outlook.
The whole 16 days is a bust. The only wave on the menu is Main Reef (Hikkaduwa), a consistent reef that usually loves a SW swell, but the wind is a total buzzkill. The water temp is about what you’d expect for this time of year, nothing special.
Starting Sunday the 6th, we’ve got a tiny 3ft SSW swell, but a 9 mph onshore WSW wind is wrecking it. The wave energy is a measly 376, and it’s all "poor surf conditions." That’s the pattern for the whole first week. Through Saturday the 12th, it’s the same mess: onshore winds, storm clouds, and surf that’s not worth the paddle. The swell tries to grow on the 10th, hitting 4ft, and the energy climbs to 1189 (moderate), but the wind stays onshore, ruining the shape.
Monday the 14th and Tuesday the 15th are just more of the same. The swell is around 4ft to 5ft, with energy in the 1100-1300 range, but it’s all choppy and onshore. Wednesday the 16th brings a cross-onshore wind at 19 mph, making it lumpy.
The only flicker of hope is late in the run. Thursday the 17th has a 5ft SSW swell with a 16-second period and 1450 energy, but the wind is still onshore. Friday the 18th and Saturday the 19th see the swell push to 6ft to 6ft, with energy hitting 2328 (strong). The period is a long 15-17 seconds, so there’s real groundswell potential. But with a 16 mph onshore wind, it’s just a messy, blown-out reef. Not a stand-out in the bunch.
This is a total blank run. The swell is either too weak or the wind is all wrong. For a kitesurfer, that 5-6ft onshore wind might be a session, but for a paddle surfer, it’s a two-week dry spell. Sometimes that’s how the cards fall.
Rusty.
