The Lowdown

Alright mate, Rusty here. Let’s break down what’s happening for the next stretch.

Right off the bat, we’ve got a long, quiet spell. The first few days are a bit of a write-off. Thursday the 20th starts with poor surf conditions and a weak, short-period NE swell around 4ft, with a light cross breeze. The combined energy is super weak at 148. Water temp is sitting at 63°F, which is about average for this time of year – nothing to write home about there.

We’ll be waiting through Thursday, Friday, and into Saturday, with nothing worth paddling out for. The wind comes and goes, but the swell is tiny and the period is short. It’s a tough stretch.

Sunday morning the 23rd offers a tiny glimmer – glassy conditions with a light W wind, and a 2ft NE swell, period bumping up to 9 seconds. The energy is still weak (55), but it’s clean. You could get a few knee-high ones if you’re desperate.

Monday morning the 24th stays small, but Monday afternoon sees a glassy E wind and a 3ft ENE swell. The energy is still weak (62), but it’s surfable. Tuesday the 25th is the first real highlight. Light rain, but a light SSW wind keeps it clean, with a 3ft ENE swell at 9 seconds. The energy ticks into moderate (106). The afternoon is even better – glassy with an ESE wind, same swell, solid energy (101). That’s your first real chance for a fun, clean session on small waves.

Wednesday the 26th gets blown out by a strong SW wind, so forget it. Thursday the 27th morning has a nice offshore SW wind and a 2ft ENE swell at 8 seconds – clean but small. Energy is weak (69). Friday the 28th morning is glassy with a calm wind, a 3ft ENE swell at 6 seconds – still weak (55), but clean.

Then we hit a big gap. Saturday the 29th and Sunday the 30th are rough with strong cross-onshore winds and messy, choppy surf. The swell picks up to 7ft on Sunday, but it’s all wind-affected. Not good.

Now, into the second week, things get interesting. Monday the 31st of August morning sees a 8ft ENE swell, period 8 seconds, energy jumping to 828 – moderate. The wind is a cross-shore N breeze, so it’s a bit lumpy. But the afternoon is a real standout: a 12ft ENE swell at 9 seconds, massive energy at 2863. The wind is onshore though, and the swell is predicted to be too big for this break. This is expert-only territory, and even then, it’s gonna be a beast.

Tuesday the 1st of September morning is the biggest of the run: a 13ft ENE swell, period 10 seconds, energy at 4457 – very strong. The wind is offshore WSW, so it’s clean, but again, this is massive. Only for the brave. The afternoon drops to 10ft, still huge.

Wednesday the 2nd of September morning sees a cleaner 7ft E swell at 10 seconds, energy 932. The wind is a clean offshore SSW. This is a serious session for experienced surfers, but the size and power mean it’s not for everyone.

Thursday the 3rd of September morning is the final real standout. A 5ft E swell at 9 seconds, energy 318, with a clean offshore SW wind. This is the best blend of size and quality for the whole period. The swell is solid, the wind is glassy, and it’s not too big. This is the one to aim for.

After that, it fades out quickly. Friday the 4th of September is back to tiny, weak surf.

So, the standout days are Tuesday the 25th for the small, clean afternoon session, and Thursday the 3rd of September morning for the best all-round conditions. The massive swells on the 31st and 1st are for experts only.

Stay safe, keep your eyes on the horizon, and I’ll see you out there.

Rusty.

A general guide to surfing at Manly-North Steyne 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 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.
