The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for Manly-North Steyne over the next couple of weeks.
Right off the bat, it’s a bit of a slow start. The first real opportunity to get wet doesn’t arrive until Wednesday 22 July. Before that, Tuesday has some swell around 4 ft to 5 ft from the ENE, but the wind is cross or cross-on, making it choppy and messy. Not worth paddling out for.
Wednesday 22 July is where it starts to look interesting. The morning brings a 4 ft ENE swell, and with a light W cross-off breeze, things are clean. But the real gem is the afternoon — glassy conditions with a NNE breeze at just 3 mph, and a 4 ft ENE swell. The combined swell energy is moderate (210). That’s going to be smooth, clean, and fun for the advanced surfer this spot is made for. Best session of the week right there.
Thursday 23 July still has some clean waves in the morning — 3 ft from the ENE with a 12 mph offshore W wind, but the swell is dropping and the energy is down to 121. It’s surfable, but nothing special. The afternoon gets blown out by a strong 19 mph offshore, so it’s a bit too clean and blown out to really enjoy.
From Friday 24 July onward, the swell really fades. We’re looking at drops below 2 ft from the ENE through to the end of the month. The combined energy drops into single digits or low double digits. It’s small, weak, and while there are some offshore winds in the mornings, the waves just aren’t there. We’re talking a long stretch of tiny, poor surf right through to the end of July and into the first few days of August.
The long-range stuff around 1 August has a pulse of very long period swell (19 seconds) from the E, but the wave height is only 0.7 ft. That’s a tease. The energy is low (28). For a beach break like Manly, that long period on such a small wave won't do much — it’s more of a point break or reef wave.
So, the bottom line: Wednesday 22 July afternoon is your standout. It’s the cleanest, most fun surf in the whole outlook. The rest of the 16 days is mostly flat or too small to bother with. Hang tight and hope the forecasts change.
Rusty.
