The Lowdown

Alright, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks at Narrabeen-Alley Rights. We’re looking at a pretty long stretch of flat, weak, and mostly messy conditions to kick things off, so don’t get too excited just yet.

The first week is pretty grim. A lot of tiny, wind-affected dribble with most days offering nothing worth paddling out for. Thursday the 10th through to Saturday the 13th are all “poor surf conditions” with swell heights barely cracking 2 feet. The energy is super low, with combined swell energy readings between 14 and 65 (weak). On Saturday the 12th, there’s a glassy window in the morning, but with a 0.7 ft ENE swell and a period of 14 seconds—that’s a long period but tiny. It’ll be clean but so small you’ll be floating. Sunday the 13th has a 3 ft NE swell but it’s short period (4 seconds) and messy with cross-shore winds.

Now, there’s a little flicker of hope on Monday the 14th morning. A clean, light north wind and a 2 ft swell from the NE at 6 seconds. The combined energy is 50 (weak), but the conditions are described as “clean” and “surfable waves but very ordinary conditions.” It’s still small and poppy, but maybe worth a quick session if you’re desperate.

From the 15th onwards, things get a bit more size but stay messy. Tuesday the 15th afternoon has a 6 ft SSE swell, with energy jumping to 281 (moderate), but it’s cross-onshore and choppy. Wednesday the 16th and Thursday the 17th are back to tiny again, though Thursday the 17th morning has glassy conditions with a 13-second period ENE swell at 0.7 ft—clean but tiny.

Finally, the standout in the whole outlook is Thursday the 24th of September morning. That’s over two weeks away, so keep an eye on it. The forecast shows a glassy 7 ft SSE swell with a period of 8 seconds. The combined energy is 578 (strong). The forecast says “expect very good surf conditions.” For a beach/sandbar setup like this, a 7 ft swell is sizey—get it on the right bank and it could be bloody fun. The glassy wind and solid energy make this the day to circle on the calendar. Just remember, it’s a long way out, so the call is promising but not locked in.

Overall, it’s a lean start. The first week is mostly a write-off. There’s a brief window on the 14th morning and a few clean but tiny moments, but the real gem is that 24th of September morning. For a spot that’s very consistent and exposed, this long gap of poor surf is a bit of a drag, but it tends not to stay this flat for long. Hang in there.

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.
