The Lowdown
G’day, Rusty here. Let’s talk Bali Bay (Glen Reef).
The first couple of days are nothing to write home about. Saturday the 18th and Sunday the 19th have small, crummy swell with cross winds – save your energy.
Monday morning the 20th is where it starts to clean up. Glassy wind, waves around 5 ft from the SSW, combined energy moderate at 663. Silky smooth conditions. A good option for intermediate surfers.
Tuesday morning the 21st is the standout. Waves at about 6 ft from the SSW, a long 14-second period, and glassy winds. Combined energy jumps to a strong 1246. This reef will handle that period well, offering good shape and consistent sets. Crowds are possible, so get there early.
Wednesday the 22nd brings a big push to 10 ft from the SW, period 12 seconds, but north winds at 15 mph keep it clean in the morning. Combined energy is very strong at 2667. This is expert territory only.
Thursday the 23rd drops slightly to 7 ft, still clean with lighter winds. Good for experienced surfers.
Friday the 24th hits 12 ft from the SW, period 15 seconds, energy over 5476 – too big for this break. Expert-only and risky.
Saturday the 25th settles to 8 ft in the morning and 7 ft in the afternoon, with glassy or light offshore winds. The afternoon session with glassy conditions is your best bet.
Sunday the 26th is messy with 7–7 ft and strong cross winds. Skip it.
Monday the 27th is clean again with 8 ft from the SW, 15-second period, light offshores, and very strong energy. Excellent for experienced surfers.
From Tuesday the 28th, it fades. Waves drop to 5 ft then 3 ft by the 30th. There’s a small clean window on Thursday morning the 30th with 3 ft from the WSW, but it’s tiny.
Sunday the 2nd of August has 5 ft WSW with clean conditions, but still just marginal.
Best bets: Tuesday the 21st for clean, consistent groundswell, and Monday the 27th for experienced surfers. Everything else is either too small, too big, or blown out.
Rusty.
