The Lowdown
Hey, Rusty here. Let’s break down what’s happening.
We’ve got a real quiet start. From Wednesday August 5th all the way through Sunday August 16th, it’s basically a write-off. The wind is cross-onshore from the west every day, moderate to fresh, and it’s choppy and lumpy with thunderstorms likely. The wave energy is moderate to strong (values from 644 to 2493), but it doesn’t matter with that wind messing everything up. You’ll see some decent size – like 6ft on Saturday morning and 7ft on Sunday morning – but the period is short and the wind is on it. No good waves here.
The first sign of life is Monday August 17th. The wind finally goes offshore in the morning and again in the afternoon. The swell drops to a cleaner 5ft – 5ft from the west. It’s only marginal, but that offshore wind makes all the difference. The combined energy is moderate (1097 to 1343). Not a standout, but it’s a start.
The real standout is Tuesday August 18th. That morning we get a solid 5ft swell from the SSW with a very long period of 18 seconds, and the energy is strong at 2435. The wind is offshore, and this is a reef break. That long-period groundswell will wrap in beautifully at Inside Reef (Hikkaduwa), giving you powerful, clean lines. The afternoon gets a bit cross-onshore, but the swell period jumps to 21 seconds and the energy hits 3379. This is the best of the whole outlook – clean, heavy, and deep. Keep in mind this is a reef break for advanced surfers only, and crowds are possible.
Wednesday August 19th brings some serious size – 8ft from the SSW – but the wind goes cross-onshore and the wave quality drops back to poor. That’s big and blown out, only for the brave. Thursday August 20th is similar with a 8ft swell, but the wind is offshore in the morning, so there might be a window for the experienced.
So the story is: you’ll wait over a week for anything worth paddling out for. The best bet is Tuesday August 18th with that long-period groundswell and offshore wind. Monday the 17th is your warm-up. Everything before that is a no-go.
Rusty.
