The Lowdown
G’day, Rusty here. Let’s break down what Dee Why Point has cookin’ over the next couple weeks.
First off, it’s flat and ugly to start. Saturday the 12th and Sunday the 13th are scrubs – small, weak waves with onshore winds messin’ things up. Energy’s low, around 322 to 173, and waves are barely 3ft to 3ft. Not worth wetting a suit.
Monday the 14th and Tuesday the 15th ain’t much better – tiny 2ft to 3ft waves, cross-onshore breezes, and chop. Energy drops to 137 or lower. Poor.
Then comes Wednesday the 16th of September. That’s the big one. A solid south swell hits – morning sees 10ft, and the afternoon pumps at 12ft. That’s expert-only territory. The swell’s from the south with a period of 9 to 10 seconds – proper groundswell – and the wind is clean cross-off from the SSW. Combined energy is huge: 1540 in the mornin’, and a massive 2717 in the afternoon – strong to very strong wave energy. The afternoon gets a good call, but the swell’s too big for this break. For the crew of experienced surfers, this is the session. Water temp is about average for the time of year.
Thursday the 17th stays big – 10ft in the morning, 8ft in the afternoon, with clean cross-off winds and strong energy (1608 and 1025). Tide might be tricky, but it’s still a big swell run.
After that, it fades fast. Friday the 18th and Saturday the 19th drop to tiny 2ft to 2ft, onshore wind returns, energy under 334. Sunday the 20th is flat – 1ft, energy in the 50s. Don’t bother.
Monday the 21st brings a bump to 5ft from the SSE, but wind is cross-onshore and messy – energy around 208. Still poor.
Tuesday the 22nd through Friday the 25th of September is mostly flat again – waves under 2ft, energy below 100, onshore or cross-on wind. A long, dull stretch.
Friday the 25th of September morning offers a small window: 6ft from the south at 10 seconds, light cross-shore wind, gentle chop – energy at 718 (moderate to strong). But the afternoon turns onshore and poor.
Saturday the 26th and Sunday the 27th wrap it up with 7ft to 5ft from the SSE and ESE, but cross-onshore wind makes it choppy, energy dropping from 734 to 415. Poor.
Bottom line: Wednesday the 16th of September afternoon is the standout – massive, clean south swell with cross-off winds, but strictly for experts. Friday the 25th morning is a distant second.

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.
