The Lowdown
Right off the bat, things are pretty flat and ugly around here. We’ve got a bit of a wait ahead. The first real chance at a wave doesn't show up until Thursday morning the 27th, so there’s a couple of days of nothing much to start.
Manly is a point break that’s fairly consistent and sheltered, but we need the stars to align.
That Thursday morning the 27th is your first real standout. You’ve got a 5ft swell coming from the south with a period of 8 seconds. The combined wave energy is moderate (415). The best part is the wind: glassy, dead calm. That’s about as clean as it gets for a point break like this. The water temp is sitting at 63°F, which is about average for this time of year.
Friday the 28th morning is another moment to watch. The swell drops to around 3ft from the south, 9-second period, but again, we get that glassy wind off the northwest. Wave energy is still moderate (281). It’s not huge, but clean and surfable.
Then on Monday the 31st morning, there’s a real interesting one. A tiny 2ft swell from the south, but the period jumps to 19 seconds—that’s very long period groundswell. The energy is moderate (455). Again, glassy wind. For a point break, that long period can wrap in nicely and give you some real shape, but the size is tiny, so it’ll be more of a longboard glide than anything powerful.
Into Tuesday the 1st of September morning, we’ve got another clean one: around 3ft from the south, 14-second period, glassy wind off the west. Energy at 454. Another solid, clean morning.
Honestly, after that first week, the second week looks pretty grim. There are small pulses, but the wind gets on it, and the swell is weak and short period. The 5th of September Saturday has a 5ft swell from the SSW, but it’s only 7 seconds and the wind is cross-off, so it’ll be chopped up and messy. Not worth paddling out for.
Overall, the best bet is Thursday morning the 27th and the Monday the 31st morning. Keep expectations in check for the rest.

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.
