Alright, Dee Why crew, Rusty here. We’ve got a bit of a mixed bag coming our way, so don’t expect firing waves every day. The first week is pretty average, with small, weak swell and dodgy winds for the most part. The whole opening stretch from the 21st to the 26th of August is a write-off – we’re talking tiny 0.7ft to 1ft slop with poor conditions and the combined energy barely getting out of the double digits (47 to 308). It’s just not worth paddling out.
Things finally start looking up on the 27th of August. That Thursday morning, a solid 1.8m (6ft) south swell rolls in with a decent 11-second period, and the wind is glassy offshore from the southwest. The combined energy is pumping at 732, meaning there's some proper grunt in the water. This is the real standout of the whole period – clean, punchy lines at Dee Why Point (Sydney) with that offshore wind keeping it smooth. The water temp’s about average for this time of year, nothing unusual there. Keep in mind, this spot is consistent and catches a lot of swell, and with a south swell like this, it’ll be lining up nicely. Because it’s a point break, that long 11-second period will give you nice, peeling waves with good shape – but it’s still clean enough for a ripping session. The afternoon goes a bit messy with a cross-onshore ESE wind, so hit it early. Crowds are often here, so expect a few other punters in the water.
After that high point, the 28th and 29th are okay but nothing to write home about – 1.0m to 1.6m (3ft to 5ft) but with messy winds or just ordinary conditions. The 30th sees a jump in size with a 2.2m (7ft) NE swell on the Sunday morning, but it’s accompanied by rain showers and a strong onshore wind, making it choppy as all hell. That combined energy hits 1013, a huge amount of power, but it’s just not paddle-friendly. Honestly, that day looks more interesting for a kite session than a surf.
The first couple of days of September (1st and 2nd) are a bit more promising again. Tuesday the 1st has a clean 1.3m (4ft) easterly swell in the morning with light offshore SSW wind – decent, surfable conditions, and the energy is 351, that’s moderate power. A solid option if you missed the 27th. After that, things fizzle out again, with smaller, weaker swells and poor winds through to the 5th. The 4th of September has a completely glassy morning with a 0.6m (2ft) long-period easterly groundswell (11 seconds), but it’s very small, and the energy is weak (93). That’s an indication the swell is too small to really get going.
So, if you want the best of the best, circle the 27th of August (Thursday morning) – that’s the one to burn a sickie for. The first week of September offers a few clean, smaller days but nothing with the same punch. The gaps in between are full of poor or marginal surf, with long waits between good windows. Stay patient.
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.
