The Lowdown
Alright, Rusty here again, giving you the imperial rundown for LBI.
First thing, the water is 77°F, which is about 4°F warmer than average for this time of year. That’s a nice little bonus – you’ll be in a shorty or less.
I’m not gonna sugarcoat it: the next week and a half is pretty grim. From Wednesday the 19th through Sunday the 23rd, we’re lookin’ at tiny, weak waves with mostly poor conditions. The swell is small, the energy is low (between 20 and 96 on the combined scale), and the wind is rarely on your side. Wednesday morning the 19th has a glassy 2ft SE swell with a clean NNW breeze, but it’s just too small. Thursday morning the 20th has a clean offshore NW wind at 6 mph but only 1ft of swell – barely a bump.
By Saturday the 22nd, we get 4ft of easterly swell, but the period drops to just 5 seconds and the wind is cross-onshore. That’s a messy, choppy mess – not worth paddling into. The energy gets up to 96, but it’s still weak.
Monday the 24th morning offers a little hope: a 1ft SE swell, 12-second period, and a clean offshore NNW wind at 6 mph. The wave comment says “surfable waves but very ordinary conditions.” It’s clean, but it’s small. Not a standout.
Then we hit another dry spell until late in the month. The best window comes toward the end. Saturday the 29th morning has a 2ft SE swell with a moderate offshore WNW wind at 12 mph and clean conditions. Energy is still low (58), but it’s the most promising we’ve seen. Sunday the 30th morning is even better: glassy, 2ft SE swell, 9-second period, with a light N breeze. The wave comment says “surfable waves but very ordinary conditions” – but that glassy morning will be your best shot in the whole run.
There’s a bump in energy on the 31st and into September 1st, with combined energy climbing past 100 (112 to 159), but the swell stays small (2ft to 2ft) and the wind is mostly cross or cross-on. Tuesday September 1st afternoon has a clean cross-off WSW wind and 1ft of ESE swell with a 12-second period – tidy but tiny.
Bottom line: if you’ve got a longboard or a foamie, the glassy windows on Sunday morning the 30th or Saturday morning the 29th are your best bets. The waves won’t be big, but they’ll be clean and you’ll have a laugh. The rest of the period, it’s a struggle. LBI is a sandbar, and it just isn’t getting the push it needs in this 16-day window.
Rusty.
