Keaulanas Surf Forecast and Surf Report

Alright folks, it's Rusty here. Let's have a look at the coming weeks. The window kicks off on Thursday the 10th of September with a bit of a mixed bag. The first few days have some clean conditions, but the juice really picks up later on. The standout period is Tuesday the 15th of September, with the best of the bunch arriving Thursday the 24th.

We're looking at Keaulanas, a beach and reef set-up that's got a consistent record. The water temp is sitting at a pretty standard 80°F, nothing unusual for this time of year, so the steamer can stay at home.

The first few days are small but tidy. Thursday afternoon the 10th sees a 2ft SSW swell with a 18-second period, but a moderate 16 mph cross-offshore ENE wind keeps it from being all that special. The energy's moderate though, clocking in at 423. Friday the 11th shapes up better. Morning brings a 2ft SW groundswell (16-second period) with a light 6 mph cross-offshore breeze. The water’s clean. That holds through the afternoon. The real gem is Saturday the 12th. Glassy conditions with calm wind or the lightest of breezes, and a clean 2ft SW swell (16-second period). That’s your pick for the first weekend, folks. The energy is moderate (245), but the lack of wind makes it the call.

Sunday the 13th stays glassy but drops to a mediocre 1ft to 2ft wave. The energy dips down to 121-144, so it’s small and a bit ordinary. Monday the 14th has a sneaky late pulse though. The morning is clean but tiny, but by the afternoon a long-period 2ft SW swell (a massive 22-second period) comes in with light offshore winds. The energy jumps to 298. That's a long-period groundswell, so it'll be clean and have that long wait between sets, but the shape should be there on the reef.

Now Tuesday the 15th is the real first standout. The morning delivers a solid 3ft SSW swell with a 20-second period, light cross-offshore winds, and very good conditions expected. The combined energy is a solid 531, right in the moderate range. That’s the best wave of the first half. The afternoon holds up too with lighter offshore winds.

From Wednesday the 16th through to Monday the 21st, things get a bit wobbly. The swell stays in the 3ft to 4ft range, but the wind picks up to a fresh 16-19 mph cross-offshore. The energy climbs into the 500-700 range, which indicates moderate to strong pushing power, but that wind strength makes it a marginal call for clean surfing. It’s not blown out, but it’s not perfect. The morning of Monday the 21st still has that moderate breeze, but by the afternoon, the wind drops back to a gentle 9 mph and the surf cleans up again. That's a decent option.

Tuesday the 22nd is a glassy beauty with light southerly winds and a 2ft to 3ft SSW swell. The energy is lower (143-249), but the clean surface makes it a lovely cruiser day.

The big highlight, and I mean the standout of the entire window, is Thursday the 24th of September. The morning shows a 3ft SSW swell with a light cross-onshore breeze, but ignore that. The afternoon is where it’s at. Glassy conditions, a 4ft SSW groundswell with a 17-second period, and very good surf conditions expected. The combined energy is 808 – strong, serious punch. That's expert territory given the size, and with that long period, the reef at Keaulanas will be handling it well. That's the one to circle on the calendar. The day after, Friday the 25th, still has a 3ft clean swell but with a slight cross-shore ripple, still very good.

No shortages of options, really. Saturday the 12th for the small fun waves, Tuesday the 15th for that first proper pulse, and Thursday the 24th for the session of the trip. Get amongst it.

Rusty.
