13th Beach-The Bluff Surf Forecast and Surf Report

G’day, Rusty here, looking out over the next two weeks at 13th Beach - The Bluff. We’ve got a proper run of swell on the way, starting this Thursday with some solid, long-period groundswell from the southwest. The water’s sitting at about 56°F, which is pretty much bang on average for this time of year, so no surprises there.

Thursday morning kicks things off with a clean 10ft SW groundswell, period a meaty 16 seconds, and a moderate WNW breeze keeping it cross-off. The combined energy is pumping at 4482, so there’s plenty of grunt behind it. That’s proper, powerful stuff – but at this size, it’s strictly for experienced surfers only. The bluff handles it, but you’ll want your wits about you. Thursday afternoon stays clean with a gentler breeze, still 10ft, but the energy drops slightly to 3841. Still serious.

Friday morning sees the swell dip just a touch to 8ft, still from the SW with a 16-second period, and the wind stays cross-off from the west. Energy is 3482 – still solid. The data flags it as excellent for those who know what they’re doing. Friday afternoon the wind swings SSW and goes cross-on, so it gets a bit messy with light wind ripples. That’s a pass for me.

Saturday is one to skip. Onshore winds from the SSE and S, dropping energy, and the wave quality goes downhill. Sunday morning is a standout though – 5ft SW groundswell, period 14 seconds, but the real gem is the NE breeze at 3 mph, light cross-off and clean. Combined energy at 1033, moderate but tidy. This is the best of the first week for anyone who wants clean, manageable waves without the full-on power of the earlier days. Crowds are often a thing here, so expect company.

Monday morning keeps it tidy with 4ft, cross-off breeze from the NE, and clean conditions. Good for a fun session, but nothing special. Tuesday sees the swell dropping right off – 4ft and then 2ft by the afternoon. Wednesday is tiny, under 3ft, and despite clean cross-off winds, there’s bugger-all wave energy (169 on Wednesday morning). A gap of a few quiet days here.

Thursday the 20th picks up again – glassy conditions with no wind in the afternoon, 4ft SW swell. That’s about as clean as it gets, energy at 729. A proper glass-off session for the patient. Friday the 21st is ruined by strong NNE winds, and Saturday the 22nd is light rain and moderate offshore from the NNW – 3ft, clean, but only so-so. Sunday the 23rd is a write-off with poor surf and lumpy conditions.

Now, looking further out, Monday the 24th brings a fresh pulse – 7ft SW groundswell, 15-second period, but strong NW winds at 19 mph make it a bit messy. Energy is 2287, so there’s power, but it’s not the cleanest. Tuesday the 25th is smaller at 6-6ft, but with cross-shore winds and a bit of chop. Wednesday the 26th sees another solid push – 10ft WSW swell, period 12 seconds, and moderate cross-off wind. Energy hits 2376, but again, the wind isn’t perfect.

Thursday the 27th is a monster – 15ft SW groundswell with a 16-second period and 16638 energy. That’s huge. The data says it’s too big for the break, and with a moderate onshore south wind, it’s going to be a wild, dangerous mess. Only for the absolute elite, if anyone at all.

Finally, Friday the 28th wraps it up with a lovely glassy morning – 6ft SW groundswell, 13-second period, NE breeze at 3 mph, and clean as a whistle. Energy is 1222, moderate. That’s a proper finisher for the confident surfer who wants clean, solid waves with no wind.

Overall, the standout is Sunday morning the 16th – clean, 5ft, light cross-off. For the brave, Friday the 28th morning is glassy and promising, but it’s two weeks out, so keep an eye on it.

Rusty.
