The Lowdown
Alright, let’s get into it. The long-range charts are showing some serious muscle for the end of the month, but the next week and a half is a bit of a mixed bag. We’ve got a solid window of groundswell early on, but it’s paired with some pretty average winds. Then it goes quiet before a big, raw west swell tries to light things up again, but the wind looks like it’s going to mess with it. Let’s break it down day by day.
We kick things off this Saturday afternoon at Cozies and Geeries (Big Island). The water temp is sitting at 65.3°F, which is pretty much spot on for this time of year. The swell is already up, a good 16.4 feet of west-southwest groundswell with a long 16-second period. The energy is strong, reading 12279. But the wind is the story here – a solid 25 mph southerly blowing cross-offshore. That’s going to make for some heavy, clean faces but it will be a battle to get out and hold your position. It’s not a day for the faint of heart.
Sunday morning, the swell backs down a bit to 11.5 feet, still from the west-southwest with a 17-second period. The energy is still strong at 5733. But the wind swings to the west-southwest at 12 mph, putting it straight cross-shore. It’s going to be a bit lumpy with a cross-chop. Sunday afternoon is more of the same, 9.8 feet of swell, energy dropping to 3959, and a bit more wind at 16 mph. Still cross-shore, still a bit messy.
Monday is a write-off. The swell holds around 9.8 feet but the period collapses to 8 seconds, which is just wind chop. The wind is up, 28 mph in the morning becoming a near gale in the afternoon, and it’s all cross-onshore. It’s going to be a washing machine out there. Not worth the paddle.
Now, Tuesday morning is where it starts to get interesting. The swell is back up to 13.1 feet, west-southwest, with a solid 16-second period. The energy is strong again at 7494. The wind eases to 12 mph from the south, and it’s cross-offshore, making for clean conditions. This is the standout of the first week. The size is pushing into the “expert only” territory, but if you’re charging, this is your window. Tuesday afternoon cleans up even more, with 11.5 feet of swell and a light 16 mph cross-offshore breeze, but the energy drops off a touch.
Wednesday through Friday, it’s all about the swell fading. The size drops from 7.9 feet down to 6.2 feet over the next few days. The period stays long, 15-17 seconds, which is good, but the energy drops right off into the low 2000s and then below. The winds are light and variable, mostly cross or cross-off, so it stays clean. It’s not going to be big, but it’ll be rideable and fun on the longer boards. Thursday afternoon has a nice window with light winds and clean conditions on 7.2 feet of swell.
Saturday the 15th is similar, small and clean, with 5.6 feet of swell. The morning has a light cross breeze, but the afternoon turns cross-off and glassy. A good day for a log or a funboard.
Sunday the 16th, the wind picks up again out of the north-east at 19 mph, making things lumpy. The swell is still small, around 6.6 feet, but the wind is going to chop it up.
Then we have a bit of a lull in the middle of the week, from the 17th through the 19th. The swell is building again, but it’s coming from the west and the wind is onshore, either from the west-northwest or northwest. It’s going to be blown out and messy. The 17th has some size, 11.5 feet, but it’s onshore. The 18th is worse, with a near gale blowing. The 19th sees the swell jump to 14.8 feet, but the wind is still on it, making it a complete mess.
The 20th and 21st, the swell stays big, 11.5-13.1 feet, but the wind is howling from the northwest and north-northwest, all onshore. It’s not going to be a surfing day; the coast is going to be a churning, blown-out mess. You’d be better off with a kiteboard.
The last day of the run, Sunday the 23rd, the wind backs off a bit and swings to the south-west, giving a cross-offshore flow. The swell is still solid, 13.1 feet in the morning from the west-southwest with a long 19-second period. The energy is huge, reading 9942. It’s going to be big and clean, proper heavy stuff. This is the other standout, but it’s a long way out, so don’t book the flight just yet. It’s promising, but we need those winds to
