The Lowdown

Alright, Rusty here, let’s break down what’s happening at Manly.

Water temp is about standard for the season, nothing wild. The first week and a half is mostly flat and mediocre, with a few so-so moments but nothing worth grabbing your board for. Then, right at the end of the 16-day window, we get a proper spike of energy that’s worth marking on the calendar.

We start with a long stretch of nothing exciting. From Thursday the 13th through the following week, the surf is small and mostly messy. There’s a little pulse on the 16th and 17th, but with cross-shore winds and short-period swell, it’s choppy and unsurfable. The first real chance to get wet is Wednesday morning the 19th – glassy conditions with a light NE breeze and a tiny 4 ft swell from the east. The combined energy is weak (143), so it’s more of a longboard or beginner session. The 20th is glassy again but even smaller.

The standout window is Wednesday the 26th. That morning, look out – a solid 8 ft S swell hits with a 10-second period, clean offshore winds from the SSW, and the combined energy is a thumping 1041. That’s proper groundswell energy, and the point at Manly should be handling it well. This is the best on offer: size, direction, and clean conditions. The afternoon gets bigger – 10 ft from the south – but the wind swings cross-off and the tide might make it tricky, so keep an eye out for closeouts or fat sections. The following days drop in size but stay clean, so there’s still a chance for a few clean lines.

If you’re a beginner, be careful on the 26th morning – 8 ft is pushing it, and the afternoon at 10 ft is expert territory. The crowds at Manly are often there, so expect company on the good days.

Bottom line: it’s a slow start, then a proper winter pulse arrives on the 26th. That’s the one to aim for.

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.
