The Lowdown
G’day, Rusty here. Let’s be straight with you—this outlook for Dee Why Point is a real mixed bag, and for the most part, it’s a long wait for the good stuff. The start is flat and messy, with onshore winds and weak, poor-quality surf. The only real standout comes mid-week next week, but it’s a beast that only the experienced should even think about.
Right now, Saturday the 12th, we’ve got a weak 3ft S swell at 10 seconds, but with a stiff 12 mph ENE onshore, it’s just choppy and sloppy. Water temp is 63°, which is about 1° cooler than average for this time of year—nothing weird, just a touch nippy. Sunday and Monday stay in the doldrums, with tiny 2ft to 3ft S swell and cross-to-onshore winds. Tuesday the 15th morning sees a tiny bump from the NE at 2ft, but period is a pitiful 7 seconds, so energy is weak at 67. It’s clean with a light offshore, but there’s nothing to ride.
Then we hit the big one. Wednesday the 16th is the only time this window fires. Morning brings a solid 10ft S swell at 9 seconds, and the afternoon pushes it to 12ft S at 10 seconds. Combined energy is massive—1247 in the morning, jumping to 2523 in the afternoon. That’s serious, raw power. Winds are cross-offshore from the SSW (22-25 mph), which will groom it, but this is a point break for advanced surfers only. At 12ft, it’s well over the 8ft mark, so beginners and most intermediates stay out. The direction is S, and Dee Why Point’s optimum is SSE, so it’s close enough to work well, but this is a heavy, powerful groundswell that will jack up and hold its shape. Expect long lulls between sets, but the ones that come through will be absolute freight trains. Crowds? This spot is often busy, so with this size, it’ll be packed with the crew who can handle it.
Thursday the 17th still has size, but it’s dropping—10ft in the morning, 8ft by afternoon—with moderate S winds. Quality is marginal, and with rain showers around, it’s not the clean, epic day Wednesday will be. After that, it fades fast. Friday the 18th drops to 3ft, and the rest of the outlook into the second week is a wasteland of tiny 1.0ft to 3ft swells, short periods, and onshore winds. The 19th and 20th have tiny clean windows with offshore winds, but the swell is barely there—combined energy as low as 35.
There’s a long gap of poor-to-flat conditions from the 18th right through to the 27th. The only flicker is Wednesday the 23rd, with a weak 3ft SSE swell and some clouds, but winds are onshore again. Bottom line: if you want a paddle, Wednesday the 16th afternoon is the one—big, raw, and for experts only. The rest is a write-off.
Stay safe out there.
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.
