The Lowdown
G’day, Rusty here. Let’s cut to it: the start of this period is a dud. Monday the 14th has a tiny 0.7m southerly swell, but the north breeze and onshore chop ruin it. Tuesday the 15th is small and ordinary—0.9m, short period, clean-ish but no power. You’d be guessing.
Then Wednesday the 16th fires up—3.5m of south swell, period 10, and the energy is roaring at 2245. That’s a serious slab of water, and while the wind is offshore and the waves are clean, this is big and heavy. Not a beginner day. Thursday the 17th follows with 3m and 3258 in the bank—same story, powerful and raw. Only experienced surfers should even think about it. The first real standout is Friday morning the 18th: 1.6m of south swell, period 9, and it’s glassy—dead calm, no wind. That’s the one. It’s clean, lined up, and the energy is moderate (450), so it’s got some push but not scary. That’s your best bet for a genuinely enjoyable session.
After that, it dribbles away. Saturday the 19th is down to 0.8m, and Sunday the 20th is nearly flat—energy at 30, which is weak. The 21st through the 24th are poor: small, onshore northeasterlies, no shape. We’re talking about a gap of several days where you’re better off doing something else. The second week is not much better—Tuesday the 22nd and Wednesday the 23rd have some size (1–1.7m) but the wind is onshore, messy, and the periods are short. Thursday the 24th through Saturday the 26th stay in the 1–1.8m range, but it’s all NE wind, onshore, and choppy. Poor conditions. Sunday the 27th has a slight cross-off and 1.6m, but it’s still not clean. Monday the 28th has 1.8m with a bit of cross-off, but the energy is only moderate (693) and the period is short. Tuesday the 29th is similar—1–1.4m, cross-off, but messy.
Manly (point) is sheltered and likes the SE direction, which the south swells match up with. But on the big days (16th and 17th), it’s going to be heavy and raw, and with some short periods, it might close out. The water’s 17°, which is a bit colder than average—about a degree off, so you’ll want a decent wetsuit.
So, your window is Friday morning. That’s the standout—clean, glassy, rideable. The rest of the run is either too big and raw or too small and sloppy. It’s not a classic stretch, but that one morning is worth the wait. Keep an eye on it, but don’t hold your breath for much else.
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.
