Hanalei Bay Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what's on the menu for Hanalei Bay.

Right off the bat, we’ve got a bit of a flat spell. The first few days are a write-off for quality surfing. Monday the 17th through to Wednesday the 20th of August, you're looking at small, weak, short-period windswell out of the east. Heights are struggling to get above 3ft, with periods under 8 seconds, and the combined wave energy is weak. It's not worth paddling out for. Thursday the 21st is even smaller, with barely enough energy to be called surf. We're looking at a solid four-day gap of nothing.

Things start to stir on Saturday the 22nd. The morning is still tiny, but the afternoon sees a pulse of longer-period swell (13 seconds) from the west-northwest. The combined energy climbs to a moderate 326, but the swell height is still only 2ft. It’s a tease. Sunday the 23rd through Monday the 24th brings a slight bump in size up to 5ft, but it's short-period stuff (7 seconds) and the wind is a moderate cross-offshore breeze from the east. The energy is moderate (231-398), but the quality is just ordinary.

Now, the real talking point is the end of the month and into September. From Tuesday the 25th of August, we see a solid building trend. The swell starts to push up to 7ft from the east-northeast, with a period stretching to 8-9 seconds. The energy is building into the strong range (570-875). By Thursday the 27th, we're looking at 8ft east swell with a 9-second period, and the energy is tipping over into the 1100’s. This is serious swell for Hanalei Bay. The wind stays a consistent cross-offshore breeze from the east, which will keep the surface reasonably clean. The standout window is Friday the 28th of August through Saturday the 29th. We’re looking at a solid 10ft to 12ft of east swell, with a 9-second period and massive combined energy over 1500. This is big, powerful, and while it’s consistent, the size means it’s strictly for advanced surfers. Beginners should stay well clear.

The water temperature sits at 80°F, with the anomaly showing it’s bang on average for this time of year. So don't expect any surprises when you hit the water. That big east swell direction is a perfect match for Hanalei’s optimum swell direction from the north, wrapping nicely into the bay.

Remember, the long-range forecast for the end of the month and into the first of September is promising, but we’re still a week or more out, so keep an eye on it. The wind should hold, but the size will be a handful.

Rusty.
