The Lowdown
Alright, this is Rusty, and I’ve got the long-range outlook for Dee Why Point coming at you in feet and miles per hour. Let’s get into it because we’ve got a big slab of time to work through.
Right now, we’re looking at a pretty tough start. From Tuesday morning all the way through to Thursday morning next week, there’s not a single good session on the cards. That’s a long gap – about a week and a half with basically nothing worth paddling out for. The swell is either tiny, on the wrong angle, or the wind has it chopped up. It’s a real dry spell for Dee Why Point.
But hold on, because things finally turn around on Friday morning, the 18th of September. That’s the standout. The morning brings a glassy, clean start with a 4ft swell from the south, and the wind is dead calm – that’s glass. The wave energy is moderate (350), and with that period around 9 seconds, it’s got some shape. For a point break, this is the one to aim for. The water temp is about average for this time of year, so nothing crazy to report there.
After that Friday morning window, it goes back to ordinary. The wind swings onshore in the afternoon and stays messy through the weekend. Then we get another interesting moment on Tuesday morning, the 22nd. Look, it’s a bit further out, so take it with a grain of salt, but the forecast has glassy conditions again with a 5ft south swell. That’s a solid size with moderate-to-strong energy (802). The period is 10 seconds, so decent shape. If this holds, Tuesday morning could be another good one, especially if the wind stays as calm as predicted. This is your second standout, but remember it’s a week and a half away.
After that Tuesday, the rest of the run into the end of September looks pretty poor. Winds are mostly onshore or cross-onshore from the northeast, and the swell gets messy or weak. There’s nothing else I’d get excited about. Even when the swell bumps up a bit, the conditions just don’t line up.
So, the plan: wait it out until Friday morning the 18th, and maybe circle Tuesday the 22nd on the calendar. That’s your best bet for clean, rideable waves at Dee Why Point. Crowds are often a factor here, so don’t expect to have it to yourself. I’ll be there for that Friday glass-off.
Rusty.

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.
