Updates in hr min s Forecast update imminent
Alright, Rusty here. Look, I’m not gonna sugarcoat it—this stretch is pretty ordinary for Manly-South Steyne (reef) over the next week or so. We’ve got a long, quiet gap before anything really gets going.
The immediate future is a bust. Friday the 3rd through to Sunday the 12th of July is basically a write-off for any decent surf. There’s just no energy in the water. You’re looking at weak, tiny swell—nothing breaking with any real push. The combined swell energy barely hits double digits for most of that first week. There’s a tiny pulse on Saturday the 4th with 3ft from the south and a period of 12 seconds, giving us 274 units of energy, but the wind is just okay. It’s not worth getting wet for.
Sunday the 5th sees a big jump in size—10ft from the south—but that comes with a strong 19 mph cross-off wind and the energy reading is high at 1654. For a reef break, that’s going to be a messy, blown-out situation. Not for the faint-hearted. Monday and Tuesday the 6th and 7th have some size in the 7ft to 8ft range, but the wind is all over the place, mostly cross or cross-off, making it a lumpy, average experience. You’d be fighting it.
Then, from the 8th to the 12th, we drop right back down. Tiny waves, low energy. For a spot that’s already inconsistent, this is a real flat spell. The water temp is about 66°, which is about average for this time of year, so nothing unusual there.
The Standout
Hold on for Saturday the 18th of July. That’s your ticket. A proper pulse of groundswell arrives. The morning session is the pick: 12ft from the south with a period of 11 seconds. The combined energy is massive at 2718. The wind is offshore from the west at 9 mph, giving us clean, lined-up waves. This is deep, powerful stuff—over 8ft, so this is strictly for experienced surfers only. It’ll be a challenging but rewarding session if you know what you’re doing. The afternoon stays big at 13ft but the wind switches onshore from the northeast, which will mess up the face. Get out early.
So, there it is. A lot of waiting for one solid day. Keep an eye on that 18th.
Rusty.

A general guide to surfing at Manly-South Steyne can be found by selecting the local surf guide option on the grey menu. Our Manly-South Steyne surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
