The Lowdown
Rusty here again. Only one spot on the menu: Lacerations on Nusa Lembongan. This is a serious reef, advanced only. The stretch is consistent, but you’ve gotta pick your moments.
We kick off Sunday morning, July 26th, with a clean 8ft SE swell, winds offshore, energy good at 1693. That’s a solid one to start with. Then things turn average from Monday the 27th through Wednesday the 29th – a little weak in period, and the quality drops.
Thursday the 30th brings a new SSW groundswell, period jumping to 15 seconds. The wave energy climbs above 1000 and the wind stays light offshore. This is the turning point. The mornings from here on are your target.
The real standout hits Saturday, August 8th. We’re looking at a 7ft to 8ft SSW groundswell, 17-second period, with gentle offshore winds and wave energy touching 3677. That’s heavy, so experts only. Sunday the 9th gets even bigger — over 10ft and more than 5300 energy in the water. The wind might turn a bit cross-off in the afternoon, but the morning is massive. These are the days you’ll be telling your mates about.
Into the second week, Monday the 10th sees a drop in height to around 6ft, but that 20-second period is something else. Huge waits between sets, but the waves that come through will be pure power.
Crowds are common here. It’s inconsistent, so when it’s on, everyone shows. Water temp is nothing special for this time of year.
That’s your lot. No other breaks to look at – just this one reef, and it could be firing.
Rusty.
