The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
It’s a slow start, but the waiting game pays off. We’ve got a solid run of swell building through the second half of the week and into the next, with clean conditions for most of the standouts. The first real green light comes on Tuesday morning, July 21st, and from there, it’s a steady pace.
Shipwrecks (Nusa Lembongan) is our main man for this outlook. This reef break is consistent and handles a south-west swell beautifully. The water temp is sitting about average for the time of year, so nothing to worry about there.
The first notable session is Tuesday morning, July 21st. The swell is a clean 5 ft out of the SSW with a 14-second period, packing a solid punch (wave energy 1093). The wind is offshore from the SE, making for clean, lined-up waves. It’s a good one, but don’t expect it to be empty – crowds are possible here.
Wednesday morning, July 22nd drops a little to 4 ft, still SSW, but the wind stays offshore from the SE. Not as big, but still clean and fun. The energy is moderate (593).
Then we hit a bit of a lull on Thursday and Friday, with smaller, wind-affected options. The real juice starts to build again.
Saturday morning, July 25th is a standout. The swell is 4 ft from the SSW, a long 15-second period, and the wave energy is pumping (1164). Wind is offshore from the ESE. This is a very good session.
Hold on for Monday morning, July 27th. The swell jumps to 7 ft from the SE, period is a short 8 seconds, but the energy is strong (1136) and the wind is offshore from the ESE. At 7 ft, this is getting into expert territory, so best for the experienced crew.
A real gem is Wednesday morning, July 29th. The swell is 4 ft from the SSW, 14 seconds, with a light offshore breeze from the ESE. Wave energy is strong (1083). Glassy conditions, clean lines – this is a beauty.
Thursday morning, July 30th sees a solid 5 ft SSW swell with a very long 16-second period. The energy is huge (1330). Wind is light and cross-off from the ENE. This is a proper groundswell, perfect for the reef.
Mark your calendars for Friday morning, July 31st. The wind is glassy from the NE, the swell is 4 ft from the SSW with a 14-second period, and the energy is through the roof (1194). This is the pick of the bunch – a classic, clean, glassy morning.
The first week of August keeps the love coming. Sunday morning, August 2nd has a 5 ft SW swell, 16 seconds, with a gentle offshore SE wind (energy 1317). Very good.
Then we get a monster. Tuesday morning, August 4th brings a 4 ft SSW swell with a massive 20-second period. The energy is off the charts (1772). Wind is moderate offshore from the SE. This is a very long-period groundswell, so expect it to be powerful and best on the reef.
The final call is Wednesday morning, August 5th. Swell is 6 ft from the SSW, 17 seconds, with a clean offshore wind. The energy is enormous (2536). This is an excellent session for experienced surfers only.
So, the standout sessions are the glassy morning of Friday, July 31st, and the powerful groundswell on Tuesday, August 4th and Wednesday, August 5th. Get out there.
Rusty.
