Table - best surf conditions forecast for Bali Bay (Glen Reef) over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what Bali Bay (Glen Reef) has got cooking for us over the next couple of weeks.
First up, we’ve got a bit of a slow start, but don’t let that fool you. The water temperature is sitting pretty average for this time of year, so no wetsuit drama. For the first few days, the swell is on the smaller side, but there’s a solid run of quality conditions coming our way.
Sunday morning (12 July) is actually a decent little opener. We’re looking at a clean 4ft SSW swell with a nice 11-second period, and the wind is light and cross-offshore. The wave energy is moderate (975), and it’s a reef break that’s very consistent. It’s a bit on the smaller side, but the conditions are right for an intermediate surfer to have a good time. It can get a crowd sometimes, so get out early.
Monday (13 July) is glassy, pure and simple. The swell drops to 3ft but the wind is dead calm and offshore. It’s a super clean, small-wave day. Not a standout for size, but if you’ve got a log, you’ll be smiling.
Wednesday morning (15 July) is where things start to get interesting. We’ve got a 4ft SSW swell, but the period jumps to 17 seconds – that’s a proper long-period groundswell. Combined with glassy, calm conditions, the reef is going to see some beautiful, long lines. The energy is moderate (998), but that period means shape and power. This is a standout session for the patient surfer.
Wednesday afternoon (15 July) sees the swell jump to 8ft, still from the SW but with a 15-second period. The energy is now very strong (3506). This is big, powerful stuff – expert territory only. The wind is a light cross-on, which will put a bit of a wrinkle on the face, but the sheer size and period will be impressive.
Thursday morning (16 July) is a serious contender for the best of the week. 8ft of SW groundswell, 13-second period, and glassy conditions. The energy is very strong (2605). This is big, powerful, and clean. Expert surfers only, but it’s going to be a proper session. The wind is glassy and the reef is exposed.
Saturday (18 July) is another cracker. The morning session has a 6ft SW swell with a 14-second period, cross-offshore wind, and very strong energy (2136). The afternoon is even better: 5ft, 13 seconds, and dead calm and glassy. Excellent conditions for experienced surfers. This is a great day to be out.
The following week gets a bit messy. Monday 20 July is a write-off with onshore wind and poor surf. The wind picks up through the middle of the week, making things choppy.
Thursday 23 July is a standout in the longer range, but it’s a big one. We’re talking 10ft of SW groundswell with a 15-second period, and the wind is light offshore. The energy is immense (3517). This is massive, powerful, and clean. The reef will handle it, but this is strictly for the experts. The afternoon is glassy and 8ft – still a beast.
Friday 24 July is similar size (10ft) but the wind is a strong 30 km/h cross-offshore. It’s still big and clean, but that wind is pumping. Only for the dedicated crew.
After that, a near-gale hits on Saturday 25 July and blows it all out. The final day, Monday 27 July, looks to be cleaning up again with a smaller 6ft swell and glassy conditions, offering a nice, mellow end to the run.
The Standout: Without a doubt, Thursday morning 16 July is the one to circle. Big, powerful, clean, and glassy. It’s the perfect storm for experienced surfers at Bali Bay. The morning of Saturday 18 July is a close second for a slightly more manageable size with excellent conditions.
Stay safe out there.
Rusty.
