The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Manly-South Steyne over the next couple of weeks.
There’s a bit of a quiet start, but things are looking up towards the end of the month and into the first few days of August. The water temp is sitting right around 64°, which is dead average for this time of year, so no surprises there.
The first real sign of life shows up on the morning of Thursday, the 30th of July. Manly-South Steyne (reef) will see a solid 6ft south swell pushing in with moderate wave energy (826). The wind will be offshore from the WSW, keeping things clean. This is a standout window for the advanced crew, but heads up – this place is *inconsistent* and *sheltered*, so you have to pick your moment. The swell direction is SSE, not the S optimum, but it’s still the best on offer for a while.
The real gem of the whole forecast looks like Friday morning, the 31st of July. The swell is pumping at 7ft from the south, carrying strong energy (1230). The south-west wind is cross-offshore, so the face will be clean. This is a serious groundswell with a 10-second period, offering proper shape and power. It’s a big one though – over 5ft, so not for beginners, and at 7ft it’s pushing into expert territory. The reef setup here should handle that long-period energy well. Word of caution: crowds are possible at this spot.
Saturday, the 1st of August, is still worth a paddle. The swell drops to 4ft from the SSE, but Saturday afternoon looks glassy with a light SE breeze and clean conditions. Nothing epic, but a fun, mellow session.
After that, the outlook gets pretty ordinary. From Sunday the 2nd through to the 11th of August, the surf is either small, junky, or blown out. There are a few mornings with clean conditions but the swell is weak or the period is too short for any real quality. The morning of the 7th of August has a 5ft swell with glassy conditions, but the period is a short 6 seconds, so expect fat, weak waves.
The long-range stuff around the 8th and 9th of August shows a bit of size (6ft to 7ft), but the wind is mostly onshore or cross-shore, making it messy. Not worth getting excited about this far out.
Overall, your best bet is Friday morning, the 31st of July. Get on it early.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Manly-South Steyne 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.
