Dee Why Point Surf Forecast and Surf Report

Alright, let’s break it down. Rusty here.

Honestly, the next two weeks are a tough watch. There’s a whole lot of nothing and a lot of wind-ruined small stuff. You gotta wait it out, but there is a payoff at the end, especially for the experienced crew.

We’re looking at Dee Why Point. Monday the 17th and Tuesday the 18th are total washouts. Tiny waves, onshore, just poor. The energy is weak (about 189) and that’s as good as it gets early on. The water is sitting around 63°F, which is about 2°F cooler than usual for this time of year, so it’s a bit nippy.

Wednesday the 19th morning gives us a little hope. There’s a 2ft swell from the ESE with a 10-second period, and the wind is glassy – dead calm. That’s a huge plus. The energy is moderate (161). The waves are surfable, but nothing special. It’s the only clean-looking session for a while though.

From Thursday the 20th all the way through to Friday the 28th of August, it’s a long, flat stretch. The swell is tiny, mostly under 3ft, with short periods and poor wind. Some mornings have clean offshore breezes, but there’s just no wave to ride. Energy readings are low, often in the double digits or low triple digits. That’s a solid 9-day gap with nothing worth paddling out for.

Then, things get serious. The forecast kicks off on Saturday the 29th of August. A solid 7ft south swell arrives, but with a short period of 8 seconds. The wind is a fresh cross-offshore, keeping it clean. The energy jumps to 847 – that’s strong. This is big and powerful, but short-period. At 7ft, it’s getting into the no-go zone for beginners. The south swell direction works for Dee Why Point, but short-period south swells can be a bit unruly.

Sunday the 30th keeps the energy pouring in. Another 7ft south swell in the morning, building to 8ft in the afternoon. Periods are still short at 9 and 10 seconds. The energy is massive (813 and 973). The wind holds clean from the south-southwest. This is big, powerful, and will be a serious challenge. At 8ft, that’s expert-only territory. The short period means it will be fast and dumpy. This is the most significant swell of the entire forecast.

Monday the 31st of August remains solid, with 7ft to 8ft south swell, but the period stays short. Winds are cross-offshore. The energy is still very strong (600-766). It’s a series of big, windy days that are more about raw power than clean waves.

Finally, moving into Tuesday the 1st of September, the swell drops to 5ft from the south, but the period lengthens to 12 seconds – that’s a proper groundswell. The energy is still very strong (807). The wind is light and cross-shore, so not glassy, but not messy. This longer period will produce better shape, with more power and longer lulls. The south swell direction is a good match for Dee Why Point. This is likely the best all-round day of the entire outlook: decent size, groundswell energy, and light winds. Remember, it’s a long-range call, so it’s promising but not locked in.

For the best session, I’d call out Sunday the 30th of August for the sheer power, but only for experts who can handle a fast, short-period 8ft wave. For the best combination of size, shape, and conditions, Tuesday the 1st of September is the standout. The 12-second groundswell, strong energy, and manageable size make it the most promising session for competent surfers.
