The Lowdown

G’day, Rusty here. Let’s have a look at what’s cookin’ for Narrabeen-Alley Rights (beach/sandbar) over the next coupla weeks. It’s a bit of a slow start, but there’s a window of hope if you’re patient.

Right off the bat, we’ve got a long stretch of not much. From now through to Thursday the 27th of August, it’s pretty grim – small, choppy, and onshore winds making a mess of things. The combined swell energy is barely registering (160 down to 40), so don’t bother paddling out unless you just want a wet float. Water temp is sittin’ around 63°, which is pretty much where you’d expect it for this time of year – no surprises there.

Now, Friday the 28th of August is where things finally turn. That morning’s got a clean 5ft swell from the SSE, with a period of 11 seconds – that’s proper groundswell energy, gonna have some push and shape. Winds are light cross-off from the WSW, so expect clean faces. The combined energy is a solid 605 – that’s moderate but with some grunt. For an advanced spot like this, that’s the standout session of the whole outlook. It’s gonna be a bit of a gem if you can sneak out. Saturday the 29th still has some leftover 5ft swell from the SSE (445 energy), but wind swings a little cross-shore, so it’s not quite as clean – still surfable though.

After that, it drops right off again. Sunday and Monday are tiny and junky, with energy down to 31 and 17. Then Tuesday the 1st of September throws up a little hope: morning brings 4ft from the SSE (340 energy) with clean offshore NW winds. That’s a solid window for a couple of hours, but by afternoon it’s back to short-period slop with NE wind. Wednesday and Thursday are flat again. Friday the 4th of September onwards is a write-off – tiny waves and onshore slop, with combined energy mostly below 50. Even a promising Monday the 7th of September bump from the SSE (317 energy, 4ft) gets ruined by fresh 19 mph winds – it’s gonna be messy and marginal.

Bottom line: this break is very consistent, but the surf quality is mostly poor. The standout is Friday morning the 28th of August. That’s the one to target. The rest of the run is either too small, too choppy, or blown out. If you’re a begginer, that 5ft might be a bit much, but for anyone else, that’s your wave.

Stay salty,
Rusty

Information about the Narrabeen-Alley Rights Surf forecast

The above surf forecast table for Narrabeen-Alley Rights provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Narrabeen-Alley Rights can be found by selecting the local surf guide option on the grey menu. Our Narrabeen-Alley Rights 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 (Narrabeen-Alley Rights) 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 Narrabeen-Alley Rights 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.
