Kua Bay Surf Forecast and Surf Report

Alright folks, Rusty here. Looks like we’re in for a proper flat spell around Kua Bay. The whole 16-day window is basically a write-off for any decent waves. We’ve got nothing but tiny, weak, and poorly timed swell—if you can even call it swell. The water temp is sitting right where it should be for this time of year, so at least a dip will be refreshing, but don’t bother bringing a board.

Starting Sunday, August 23rd, it’s tiny. A 2 ft, 12-second WNW swell rolls in but with a light cross-onshore breeze, it’s just messy and weak, with combined energy of only 169. That’s barely a ripple. The next few days are even worse. Monday sees a 0.7 ft WNW swell, Tuesday morning is completely glassy but flat, and by Wednesday afternoon we’ve got a 2 ft NNE windswell with a period of just 5 seconds—that’s pure chop, not surf. The combined energy drops to 30. It’s a long, empty stretch.

We skip through the rest of the week with nothing but flat, glassy mornings and tiny, short-period junk. Thursday and Friday mornings bring 2 ft and 2 ft NE windswell, periods of 5 seconds, energy in the 20s and 30s—just not worth a paddle. Saturday the 29th is more of the same: a 2 ft NNE windswell, 5-second period, 25 energy. It’s getting depressing.

Moving into the last week of August and first days of September, we get a faint pulse of longer-period groundswell. Sunday the 30th afternoon shows a 1.0 ft, 15-second SW swell, but it’s cross-on and the energy is only 36. Monday the 31st has a similar 1.0 ft, 15-second SW swell, but still cross-shore and weak. Tuesday September 1st is flat again. The following days are all under 0.7 ft with periods of 10-11 seconds, and energy in the single digits—you’d be better off doing tai chi on the beach.

The only faint glimmer comes on September 6th and 7th. Sunday the 6th afternoon sees a 1.0 ft, 15-second WNW groundswell, cross-off wind, and combined energy of 47. Monday the 7th morning bumps up to 2 ft, 14-second W swell, with cross-off winds and energy of 98. Still weak, but at least it’s clean and has some long-period shape. For a reef break like Kua Bay, that long-period groundswell could wrap in okay, but it’s still tiny. Don’t get your hopes up.

Bottom line: there’s nothing here for surfers. The whole 16-day forecast is a bust. If you’re desperate for a wave, look elsewhere. But if you’ve got a kite, the stronger winds on September 5th and 6th might make for a more interesting session than paddle surfing. For now, it’s a flat, clean, glassy pond with zero energy. Forecasts can change, but right now, don’t hold your breath.

Rusty.
