The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Manly-North Steyne. Gotta be straight with you – it’s a tough start. We’re lookin’ at a solid week of barely a ripple before things finally get their act together.
The opening days are a write-off. From Thursday the 30th of July right through to Wednesday the 5th of August, you’re lookin’ at tiny dribbles under 1ft, mostly from the ENE, with combined energy readings barely hitting double digits (7). It’s just not worth paddling out for that. The wind is often clean or offshore, but there’s simply no swell to work with.
There’s a tease on Sunday the 2nd of August afternoon. A 6ft SE swell rolls in with a solid 12-second period and moderate energy (860), but it’s got a 16 mph NE onshore wind on it. That’s gonna be a mess. For an advanced spot like this, that’s more of a kite-surfing setup than a paddle session.
The first real sign of life comes Monday the 3rd of August. The morning has a 4ft SE swell (250 combined energy), but it’s cross-offshore with a moderate breeze. It’s marginal, but you *might* find a rogue one. The afternoon cleans up with a light offshore wind from the W and a 3ft SE swell at 11 seconds (182 energy). It’s ordinary, but surfable.
Now, the standout window. You wanna circle Monday the 10th of August and the following days. Monday morning sees a 5ft NE swell, period of 6 seconds, with a light cross-offshore breeze and clean conditions. The combined energy is 265 – a solid step up. It’s not perfect, but it’s the best we’ve seen.
But the real gem? That’s Wednesday the 12th of August. The morning brings a 6ft ESE swell, 11-second period, and a clean offshore WSW wind at 16 mph. The combined energy jumps to 786 – strong, powerful stuff. This is proper groundswell, and for an exposed break like Manly-North Steyne, that’s gonna produce some serious, well-shaped lines. The offshore wind will be holding ‘em up, making for some sick, hollow walls. It’s best for the advanced crew who can handle that size and power.
The energy holds through Thursday the 13th (4ft ESE, 302 energy) and Friday the 14th (4ft ESE, 292 energy) with offshore winds continuing. Thursday afternoon gets a bit of a cross-shore bump, but the mornings are golden.
So, if you’re keen, don’t bother for the first week. Hold out for that Monday the 10th, and absolutely be on it for the Wednesday the 12th. That’s the one to get excited about. Water temp is about average for this time of year, nothing weird going on.
Rusty.

Information about the Manly-North Steyne Surf forecast
The above surf forecast table for Manly-North Steyne provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Manly-North Steyne can be found by selecting the local surf guide option on the grey menu. Our Manly-North Steyne 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-North Steyne) 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-North Steyne 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.
