The Lowdown
Alright mates, Rusty here. Let's break down the next couple of weeks.
The start of this run is a right-off. From Friday the 14th through to the 21st, it's a week of ugly, onshore conditions with weak, short-period swell. There are a few clean reprieves, like early Saturday the 15th, but the surf is just not there. It's a real dry spell, so don't bother waxing up for a while.
The entire picture changes in the second week. The one to get amped on is Tuesday the 25th. We're looking at a 12ft south swell with an 11-second period, and the energy is massive – 5029, which is as strong as it gets. It's supposed to be glassy with a light north wind, which is perfect for our south-facing point at Manly. This is heavy, serious surf – for experts only, no question. This is the standout of the whole window.
A couple of days before, on the 23rd, there's a bit of a pulse with 6ft to 7ft of south swell, but the conditions are iffy and the tide looks like it could spoil the party. Not a guarantee.
After that big Tuesday, it backs down. Wednesday the 26th is still big at 8ft, but the north-east wind will chop it up. Thursday the 27th has a late arvo window with good offshore west-south-west wind and 5ft of south-south-east swell – that's a clean, solid option. Friday the 28th morning is also looking glassy with 5ft of south-east swell.
Also, the water is about 3°F colder than normal for this time of year, so bring the extra rubber.
So, my advice: sit tight, save your energy for the 25th, and keep the 27th and 28th on the radar for some cleaner waves.
Rusty out.

Information about the Manly Surf forecast
The above surf forecast table for Manly provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Manly can be found by selecting the local surf guide option on the grey menu. Our Manly 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. If you surf the same spot (Manly) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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 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.
