The Lowdown
Alright, mates, Rusty here. Let’s break down the next couple of weeks at Dee Why Point.
The forecast starts off flat and ugly. From Friday the 4th through the weekend, it’s small, junky, and wind-blown – think 2 to 3 foot of disorganized south swell with onshore and cross-shore breezes. Water temp is 64°, right around the norm for this time of year. Not worth suiting up.
We get our first real window on Monday the 7th. The morning session is clean – 5 foot of south swell with a 9-second period and a touch of offshore west wind. The energy is moderate (349), and the point should have some fun lines. The afternoon turns to chop with an east-southeast breeze, so hit it early.
Tuesday the 8th sees a jump in size – 7 to 8 foot from the south-southeast. The energy is pumping hard (839 and 1191), but the wind plays games. The morning is clean with a cross-off breeze, but that size is serious. The afternoon has onshore wind and a longer 11-second period, turning it into a washing machine. This is big-wave territory, only for the experts.
Wednesday the 9th is back to a more user-friendly 5 feet in the morning with light offshore winds and moderate energy (331). The arvo gets messy again with a fresh southerly, so make the most of the morning glass.
Thursday the 10th is the biggest, hitting 8 foot with a strong energy reading of 1197. But the howling south-southeast wind makes it lumpy and cross. The afternoon cleans up a bit with a cross-off, but you’re still dealing with heavy, powerful sets. Not a day to be casual.
Now for the standout: Friday the 11th. The morning has very good surf conditions – a clean 6-foot south swell with a proper 11-second period. The wind is a light cross-off, and the energy is strong (934). This is the total package: size, power, and clean conditions. Crowds are likely, but for a wave this good, that’s the price you pay.
After that, it’s a long fade. The weekend drops into poor onshore slop. The second week is mostly a bust – a brief, marginal window on Tuesday the 15th with a clean but smaller 6-foot swell and a cross-off breeze, but it’s not the same quality. From there, it’s small, weak, and messy for the rest of the period.
In short: the Monday morning session is your starting point, but Friday the 11th is the day to get excited about. That’s the one.
Rusty.
