The Lowdown
Alright, this is Rusty comin' at ya from the beach. Let's be honest, the next couple of weeks are lookin' pretty grim for a proper paddle. We’ve got a real flat spell headin’ our way, but there's a flicker of life right at the very end.
The water temp is sittin' at a nippy 62°F, which is about 2°F colder than usual for this time of year. You're gonna want the thick rubber, mate.
For the first ten days or so, it’s a write-off. We're talkin' tiny little windswells and cross-shore junk. Monday the 26th of August shows a bump of 6ft to 6ft from the ENE, but it’s short period slop around 6 seconds and the wind is cross-off. The energy is moderate, sittin' around 198 to 246, but that wave comment says it's marginal. Not really worth paddlin' out for.
Now, mark your calendar for Thursday the 27th of August. This is the only real standout in the whole run. Manly-North Steyne should wake up to a clean 6ft swell from the NE. It’s still a short period of 7 seconds, so it’ll be a bit lumpy, but the wind is a sweet offshore from the SW at 9 mph. The combined energy jumps up to a strong 486, and the wave comment says to expect good surf. This is the morning session to aim for. Just be aware the wind switches around to a messy cross-onshore by the afternoon, so get out early.
Everything after that drops right back off into the doldrums again. A few tiny pulses but nothing that’s gonna get a surfer out of bed.
So the takeaway? There's a solid nine-day stretch of nothing followed by a single, promising morning on the 27th. It’s not a classic forecast, but that Thursday mornin' could be a little gem if you're keen and can read a short-period NE swell.
Stay frothy,
Rusty

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-North 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.
