Kewalos Surf Forecast and Surf Report

Alright, let’s chew on what’s goin’ down at Kewalos. This is a reef setup that really wants a swell from the SSE, but we’re gettin’ a lot of ENE energy, so it’s a bit of a compromise. The water’s a warm 81° – just about average for the season.

The start of the window, Thursday the 27th of August, is slow. There’s a small, long-period south swell around 4 ft, but the energy is only moderate (929). That ENE wind is blowin’ 19 mph, cross-off, so it’s clean but the surf is just marginal. That little bump fades fast through Friday, droppin’ to 3 ft with a 14-second period, and then Saturday the 29th we get a short, weak windswell – only 6-7 seconds, 5 ft. It’s bumpy and messy through Monday.

Tuesday the 1st of September into Wednesday the 2nd shows more life. The swell holds around 6-6 ft from the ENE with an 8-second period. The energy climbs to 913 (moderate), and the cross-off wind keeps it clean at 16-19 mph. Still marginal, but there’s a wave.

From Thursday the 3rd to Saturday the 5th of September, the energy drains away. The swell drops to 4 ft, the period stretches to 9 seconds, and the energy bottoms out at 312 (weak). Sunday the 6th sees a pulse again: 5 ft, longer 11-second period, and energy at 680. That’s a little more interestin’, but still just marginal.

The first real standout is Monday the 7th of September. The combined energy hits a strong 1007-1138 as the swell builds to 6-6 ft from the ENE with a 10-second period. Moderate cross-off wind from the NE at 16 mph. Clean and powerful.

Without a doubt, the best day is Tuesday the 8th of September. The swell is 7 ft from the ENE, 10-second period, and the energy is poundin’ a strong 1236-1315. The wind goes whisper-light – only 6 mph from the ESE, then NE, and the afternoon goes glassy. That’s the one to circle. 7 ft on a reef is expert-only territory.

Wednesday the 9th holds with a 7 ft swell, 11-second period, very strong energy (1447), but the wind kicks up to 12 mph. Thursday the 10th of September delivers another diamond: the swell pushes to 8 ft, period is 10 seconds, and the wind goes glassy – only 3 mph with rain showers. Energy is very strong at 1704. This is a big, clean, expert wave. Friday the 11th gets even bigger at 10 ft, but the period shortens to 9 seconds and the wind goes cross-on – it’s a roping, onshore mess.

So the crystal-clear winners are Tuesday the 8th and Thursday the 10th of September. The rest of the window is for the patient, tide-watching crew.

Go get some.
