The Lowdown
Alright, Rusty here. Let’s talk about what’s on the menu for Manly over the next couple of weeks.
It’s a bit of a slow start, honestly. We’ve got a long stretch of pretty ordinary conditions coming through. From Sunday, the 30th of August, right through to the end of the first week of September, the surf is just not cooperating. The swell is small, the wind is all over the shop, and the quality is poor. You’ll be looking at a solid week of nothing really worth paddling out for. The energy is weak, with combined swell readings barely cracking 200, and often sitting below 100.
Things finally start to look up around Sunday, the 6th of September. That morning, Manly gets a bit of a pulse – a clean 6ft S swell, with a 10-second period. The wind is a light offshore from the S, so the conditions should be clean. The energy jumps up to 722, which is a decent kick. This is the first real standout of the period. It’s not a monster, but after that long flat spell, it’s a welcome sight. It’s a good size for a point break, but at nearly 6ft, it might be a bit much for absolute beginners.
Looking further ahead to the second week, the real gem is sitting on Friday, the 11th of September. That morning, Manly is looking at a proper 10ft S swell, with a 10-second period. The wind is glassy, dead calm. This is a big one. The combined energy is a massive 1616. This is expert territory, no doubt. That’s a powerful, clean, south swell hitting the point with no wind. It’s a long-range call, so keep an eye on it, but that Friday morning window is the one to circle on the calendar. The afternoon does get messy with onshore wind, so get it early.
Between those two standouts, you’ve got a mix of small, clean days and blown-out afternoons. The 8th and 13th of September have some glassy morning windows, but the swell is tiny – under 2ft. Not enough for a proper session, but maybe a longboard cruise if you’re desperate.
The water temp is sitting at 63°F, which is about 1°F below normal. Nothing wild, just your average late winter chill.
So, to sum it up: the first week is a write-off. The 6th of September is your first proper chance, and the 11th of September morning is the big one to aim for. Get on it.
Rusty.

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.
