The Lowdown

Alright, let’s get into it. This is Rusty, and I’m looking at the next couple of weeks for Manly.

Honestly, it’s a pretty slow start. The first week is mostly a write-off for decent surf. We’ve got a gap of about four days where there’s really nothing worth paddling out for. The wind is all over the shop, mostly cross or cross-onshore, and the swell is small and weak. Monday the 19th of August morning shows a glimmer of hope with glassy conditions and a 4ft swell from the ESE, but the period is a short 6 seconds and the energy is weak (202), so it’s just ordinary, mushy waves. Not a standout.

The real highlight, the one you’ve been waiting for, lands on Sunday the 23rd of August. The morning is where it’s at. We’ve got a solid 10ft swell from the south, with a 9-second period, and the combined energy is pumping at 2743 – that’s strong wave energy. The wind is a light offshore from the WNW, making it glassy and clean. This is excellent surf, but at 10ft, this is for experienced surfers only. Beginners, stay on the beach for this one. Manly is a point break, and with that south swell, it should handle the size well. The water temp is about average for this time of year, so no surprises there.

The following Monday morning, the 24th, still has some clean 5ft south swell, but it’s a step down in energy. Tuesday the 25th morning sees a 6ft south swell with a cross-shore breeze, but it’s marginal.

Looking further out, the second week is a bit of a mixed bag. Thursday the 26th and Friday the 27th have some solid 6-6ft south swell, but the wind is howling from the west at 15-22 mph, making it clean but very windy. The energy is decent (856 on the 26th morning), but it’s a battle. The best bet in that second week might be Saturday the 29th morning, with a 5ft swell from the NE, clean cross-offshore wind, and moderate energy (501), but it’s described as marginal due to tide issues. Still, it’s a better option than the rest.

So, to sum it up: the standout is Sunday the 23rd of August morning. That’s the one to circle on your calendar. The rest is either small, windy, or just ordinary. Keep your expectations in check.

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.
