The Lowdown
G’day, Rusty here. Let’s talk about what’s goin’ down at Dee Why Point over the next couple weeks. There’s a few windows that are gonna get your heart pumpin’.
We start this Friday the 11th with some solid lines. A 5ft swell from the SSE, with a light cross-off breeze out of the SSW, keepin’ it clean. The water temp is 64°, right about normal for the season. The energy’s in the moderate zone (509). A decent session for the advanced crew.
Saturday the 12th is the true stand out. Glassy, windless conditions. The swell drops to 4ft, but the period stretches out to a solid 12 seconds from the SSE – just perfect for this point. That long period means more power and better shape. The energy is still moderate (484). It’ll be clean as. Just know the crowds show up often here, so be sharp.
Then we hit a quiet patch. From Sunday the 13th through Tuesday the 15th, it’s small, weak, and mostly messy. Swells under 3ft, winds are cross-on or onshore. About a 3 to 4 day lull.
Wednesday the 16th brings a big pulse. 10ft in the morning, then a solid 12ft in the arvo, all from the south (9-10 second period). Wind stays cross-off, so it’s clean, but that’s way too big for this spot unless you’re a full-on expert. The wave energy is massive (2601). Not for the faint-hearted.
Thursday the 17th stays big – 8ft in the morning, 7ft in the arvo. Still clean with cross-off winds, but still only for the pros. Energy stays strong (1158 to 734).
Friday the 18th gives us a calm morning with glass-off conditions and a tiny 2ft swell. But the period is a massive 20 seconds from the SSE – that’s a very long groundswell. Energy is moderate (578). It’ll be clean, but those long-period swells can be tricky on the point. Fun little waves if you time it right.
From the 19th to the 22nd, it’s mostly small, weak, and onshore. Nothing worth getting wet for.
The 23rd of September brings another big south swell – 10ft – but the wind is cross-on and the period’s only 8 seconds. Choppy and messy.
The final highlight is Thursday the 24th. Morning glass, 6ft from the SSE, with an 8-second period. Moderate energy (411). Clean and solid. A great way to close out the 16 days.
So, for the best of the best: Saturday the 12th morning – glassy perfection. Thursday the 24th morning as a backup. The big stuff mid-month is for the diehards only.
Rusty, out.

Information about the Dee Why Point Surf forecast
The above surf forecast table for Dee Why Point provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Dee Why Point can be found by selecting the local surf guide option on the grey menu. Our Dee Why Point surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Dee Why Point) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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 Dee Why Point 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.
