The Lowdown
G’day, Rusty here. Let’s lay it out plain for Dee Why Point over the next couple of weeks. It’s going to be a grind, with a long flat stretch before we get a real pulse of energy.
The first week is almost a total write-off. From Wednesday the 9th through to Tuesday the 15th, we’re looking at surf dropping from a messy 10ft down to nothing. Winds are mostly cross-off or onshore, and there’s barely a pulse in the water. It’s the kind of run that has you doing boat maintenance instead.
One little window appears on the morning of Saturday the 12th. There’s a 4ft SSE swell with a 12-second period, and the wind is dead glassy. On a point like this, that’s a recipe for clean, lined-up sets. The energy is weak though (478), so it’s not going to be powerful, but if you’re after a longboard glide, this is your moment.
Then it flatlines again for the rest of that week. Monday the 16th tries to build a bit of size to 4ft, but it’s onshore and messy. Not worth the paddle.
Now, the real action starts on Friday the 18th afternoon. A solid S pulse hits with an 8ft swell, but the period is a short 7 seconds. Offshore wind makes it come alive, and the energy climbs to a moderate 659. It’s gonna be raw and powerful, proper point surf. This is the first standout of the window.
But the big one arrives on Saturday the 19th. The swell jumps to a solid 10ft from the SSE with an 11-second period. Energy is strong at 1788. The wind is cross-shore so it’ll be lumpy on top, but the size and grunt are unmistakable. This is strictly for experts—over 8ft and heavy. If you’re not comfortable in big, powerful surf, sit this one out on the rocks.
After that, the ocean backs right off again. Sunday the 20th onwards is small, onshore and flat, with a brief, unimpressive bump on the 23rd that’s onshore and not worth the effort.
So the game plan is simple. If you’re desperate, hit the glassy Saturday morning on the 12th for clean lines. But the real windows are Friday afternoon the 18th for clean, powerful conditions at 8ft, and Saturday the 19th for the biggest, rawest swell of the period at 10ft—just be sure you know what you’re doing.
Water temp’s sitting at 64°, which is about normal, so the wetsuit needs are standard for spring.
Keep your eyes on the forecast and be ready to move when that Friday groundswell hits.
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.
