The Lowdown
Alright, Rusty here. Let’s look at what’s coming up for the next couple of weeks.
We’ve got a good run of surf starting Friday the 28th of August and carrying through well into the second week of September. The water is sitting at 29.3°, which is a touch warmer than normal for this time of year – a nice little bonus.
Friday morning kicks things off with a clean, glassy 2ft SW groundswell, period a solid 19 seconds. Combined energy is moderate (475). Small but pristine. Friday afternoon the swell bumps up a bit to 2.3ft, still glassy, energy climbing (611). A lovely start.
Saturday the 29th sees a real step up. Morning glass, 4.3ft SW swell with a 16-second period, energy getting strong (935). The afternoon gets a cross-on breeze, but the swell holds at 4.6ft and energy hits four digits (1061). Still good, just not as clean.
Sunday morning the 30th is another standout – glassy, 4.9ft SW swell, period 14 seconds, energy 979. That’s fun size. Afternoon turns onshore, so get out early.
Monday the 31st and Tuesday the 1st of September keep the pattern: clean mornings with 3.6ft SW swell, glassy winds, energy in the 400-500 range. Afternoons get bumpy.
Wednesday the 2nd of September is a little different. Morning is small (3ft) with a cross breeze, but the afternoon turns it on: 2.6ft SW swell, period 17 seconds, clean cross-off breeze. Energy 688 – a nice surprise.
Thursday the 3rd offers glassy 2.3ft SW swell in the morning, period 16 seconds, energy 744. Small but clean.
Now, the real standout is Saturday the 5th of September. Saturday morning is the pick of the whole forecast: glassy, 5.6ft SW swell, period 16 seconds, combined energy hitting a strong 1465. That’s excellent surf, but at that size it’s for experienced surfers only – beginners should stay on the beach. The afternoon gets a cross-on breeze, so go early.
Sunday the 6th of September keeps the quality high with a glassy 4.9ft SW swell, period 15 seconds, energy 1026. Another one for the more experienced. The afternoon stays glassy with 4.6ft – a great all-round day.
From Monday the 7th through to Saturday the 12th of September, the surf backs off a little, but there are still plenty of clean mornings with chest-to-shoulder high SW swell, periods around 14-16 seconds. The morning of the 10th and the 11th both look solid with clean conditions and energy in the 900s. The 12th is smaller but still rideable.
Overall, there’s surf on offer nearly every day. The absolute standouts are the morning of Saturday the 5th of September and the morning of Sunday the 6th. If you can only pick one, go for that Saturday morning – glassy, strong, and powerful.

Further information to help with frequently asked questions about our surf forecast for Quatro-Once (411) may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
