The Lowdown

Alright, grab a coffee and listen up. This is a bit of a mixed bag for the next couple of weeks at Narrabeen-Alley Rights. The first few days are a write-off, but we’ve got one solid window that’s worth circling on the calendar.

We start off flat and ugly. Thursday the 27th is a complete no-go with small, weak 2ft swell from the ENE and a messy cross-onshore breeze. The wave energy is pathetic at just 54. You’d be better off doing anything else.

Then we hit the good stuff. Friday morning the 28th is the standout. The wind goes glassy out of the WSW, the swell jumps to 6ft from the SSE, and combined energy is a solid 669. That’s proper groundswell with an 11-second period, and it’s lining up for the advanced crew. It’s a clean, powerful morning with the offshore wind, but it’s a short window – by Friday afternoon the wind swings onshore and it’s back to poor.

Saturday and Sunday fade quickly. Saturday morning has some 4ft from the SSE, but the wind is cross-shore and the quality is marginal. By Sunday morning we’re down to 2ft and clean but ordinary. The energy is already dropping to 122.

Then there’s a massive gap. From Monday the 31st all the way through to the start of September, the surf is tiny. We’re talking 1ft or less, mostly from the ENE, onshore winds, and the energy reading barely cracks 70. The second week looks bleak – a few clean offshore mornings in early September, but the swell never comes to life. The only real change is on Saturday the 5th of September afternoon, when a 3ft wave from the NE pops up, but it’s a short-period 5-second windswell, and it’s still ordinary. After that, it’s back to flat.

Nothing in the second half of the outlook suggests any real hope. The wind is offshore or clean, but the swell just isn’t there. Combined energy readings are often in the low teens or single digits. It’s a long stretch of nothing.

The water temperature at Narrabeen-Alley Rights is hovering around 64°F, which is about normal for this time of year.

So, bottom line: if you’re an advanced surfer, Friday morning the 28th of August is your only shot. Get out there early, because the rest of the window is a flat spell with a few tiny, forgettable bumps. Even the bigger swells later on are just windswell with no punch. It’s gonna be a waiting game.

Rusty.

A general guide to surfing at Narrabeen-Alley Rights can be found by selecting the local surf guide option on the grey menu.

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.
