The Lowdown
G’day, Rusty here. Let’s break down the next couple of weeks.
Right now, it’s flat and pretty lifeless. We’ve got a whole run of weak, disorganized slop from Wednesday the 19th right through to Tuesday the 25th. The energy readings are low (between 17 and 268), the swells are short-period and from all over the compass, and onshore winds are messing up most of what little there is. A few mornings look glassy, but there’s just no push. It’s a waiting game.
Wednesday the 26th, things start to move. A moderate South swell fills in, but it’s still rough around the edges. The morning is clean with an offshore wind, and energy jumps to 258. It’s rideable, but it’s just a warm-up.
The first real standout is Thursday the 27th. The morning session is the pick of the first week. Swell pushes up to 1.5m from the South (343 energy), and with a light westerly cross-offshore breeze, Dee Why Point will be clean and lined up. Water temp is 17°, which is about 0.7° cooler than normal for this time of year—not a major shift, but you’ll feel it. This is the one to get before the seabreeze ruin the arvo.
Friday the 28th eases off a touch, but still surfable.
Now, mark your calendars for Saturday the 29th. That’s the big one. Swell jumps to 2.4m early with energy at 963—a proper push. The wind is a fresh offshore westerly, so the faces will be clean. This is expert territory; it’s too big for beginners. By the afternoon, it’s hitting 3.0m with energy at 1482, and the offshore wind kicks up to 30 km/h. That’s a serious, heavy ocean. Only the well-prepared need apply.
Sunday the 30th is still huge—3.0m—but the wind swings to a strong 40 km/h southerly, making it cross-offshore and lumpy. The energy is cranking (2775), so it’s a powerful, challenging day for experts only.
Monday the 31st, the swell backs down slightly to 2.5m, but it’s still a long-period Southerly groundswell (11 seconds). The morning wind eases off, but it’s cross-offshore. This is a big, powerful swell—better suited to a point or reef break where it can hold its shape. On a beach break like this, it might be a bit straight and difficult.
The first few days of September are a fade-out. Tuesday the 1st has leftovers but onshore wind. Wednesday and Thursday the 2nd and 3rd drop right back down to small, clean leftovers at best.
So, here’s the call: wait for Thursday the 27th morning, and be ready for the monster on Saturday the 29th. The long-range stuff is promising but less certain, so keep checking back. The slow start is just the price of admission for that late-week payoff.
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.
