Lyall Bay Surf Forecast and Surf Report

G’day, I’m Rusty. Let’s have a look at what Lyall Bay’s got cooking over the next couple of weeks.

Right off the bat, the first few days are pretty ordinary. Tuesday morning (25 August) is a write-off – 25 mph nor’westers and only 3 ft of southerly swell with 421 (moderate) energy – it’s messy. The whole of Tuesday and Wednesday stays bleak; winds are up and the swell is small and weak, barely scraping 300 energy units. Wednesday morning (26 August) has a brief moment with 3 ft SSW swell and a 15-second period, but 19 mph offshore winds make it a tough paddle. Not worth getting excited about.

Thursday 27 August is where things start to turn. The morning is a bit average – 6 ft SSW groundswell with a 17-second period, but a light cross-shore Easterly makes it a bit lumpy. The afternoon, though, is the first real standout. You’ve got 6 ft southerly swell, 15-second period, combined energy of 1688 (strong), and a light offshore breeze from the NNE. That’s clean, lined-up, and for experienced surfers only – this is the best session in the first week.

Friday 28 August gets ruined by a near gale – 34 mph offshore winds make it nearly impossible to paddle into the 4 ft swell. Saturday and Sunday stay small and weak, with energy dropping below 250. Sunday morning (30 August) has a pathetic 4 ft six-second windswell – 105 energy (weak) and ordinary conditions.

Now, Monday 31 August morning is another cracker. 6 ft southerly swell, 14-second period, combined energy at 1340 (strong), and a light offshore cross-wind. Clean, powerful, and again, one for the experienced crew. The afternoon turns ugly with 16 mph southerly onshore and 12 ft of messy swell – too big and blown out.

Tuesday 1 September stays decent but only for seasoned surfers: 8 ft southerly sets, 12-second period, strong 2120 energy, but 22 mph north offshores make it a battle to get out. Wednesday and Thursday are a write-off – gale-force winds and big, onshore slop.

The second week gets interesting. Friday 4 September morning delivers an excellent window: 7 ft southerly groundswell, 14-second period, 1604 energy, and a gentle 9 mph offshore breeze. Clean, powerful, and for experts only. Saturday 5 September is smaller – 4 ft SSW swell with 503 energy – but light offshores make for a clean, user-friendly session. Conditions fade from Sunday 6 September onward, with tiny 1.0 ft SSW swell and near gale winds through to Tuesday 8 September. The final day, Wednesday 9 September, sees a 7 ft SSW pulse with 1090 energy, but 28 mph cross-off winds ruin it.

Best on offer: Thursday 27 August afternoon and Monday 31 August morning are the true standouts – both clean, strong, and long-period. For the second week, Friday 4 September morning is the pick, but it’s less certain this far out.

Lyall Bay is a fairly exposed beach break, and the water temp is about average for this time of year – nothing weird going on. This spot can get crowded, so expect company on the good days. The long-period groundswells (over 15 seconds) will be better shaped but can break a bit straight on the beach; keep that in mind.

No kite surfing calls here – the good days are pure paddle surfing.

Stay frothy,
Rusty.
