The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this Dee Why Point outlook is a real mixed bag, with a lot of waiting around for the good stuff. We’ve got a solid 16-day window ahead, but the first week is mostly about picking your moments. The real standout is a big one, but it’s a long way off and it’s for the big dogs only.
Alright, let’s start with the early days. From Saturday the 18th right through to the end of the week, the surf is pretty ordinary. The swell is small, around 3 ft to 3 ft, from the east, and the period is short, around 6 to 9 seconds – that’s weak, short-period windswell, with combined energy values between 61 and 131, so not much to work with. The winds are mostly cross or onshore, making it choppy and messy. There’s a brief window on Monday morning the 20th: we get a 5 ft east-northeast swell with a 10-second period (moderate energy at 687), and a light offshore wind from the west. That’s clean, but it’s only for a few hours before the wind swings onshore. The afternoon is a write-off. For the rest of the week, it’s tiny, inconsistent, and often blown out. Wednesday afternoon the 22nd goes glassy, but the swell is only 3 ft – not worth paddling out for.
Then we hit Thursday the 23rd afternoon, and things change. A new 7 ft south swell rolls in with an 8-second period, giving us a solid push of energy (565). But the wind is cross-shore from the southeast, so it’s bumpy. The next morning, Friday the 24th, is a bit better with a 4 ft south swell and a light cross-offshore wind from the southwest, keeping it clean. Still, it’s nothing special.
After that, we go into a real quiet spell. From Saturday the 25th all the way through to Tuesday the 28th morning, the swell drops right off – we’re looking at 1 ft to 2 ft from the south, with long periods (up to 14 seconds) but virtually no energy. The combined energy values are down in the 55 to 106 range. It’s a dead period. You’d be better off doing something else.
Things start to perk up a bit on Tuesday the 28th afternoon. The swell picks up to 4 ft from the south (9 seconds, energy 238), and the wind goes glassy from the west. That’s clean, but it’s still only a marginal wave. Wednesday the 29th offers similar small surf, but Thursday the 30th is a write-off again with tiny 1 ft swell.
Now, here’s the big one. Mark your calendar for Friday the 31st of July. This is the standout. We’re looking at a massive 13 ft south swell with a 13-second period – that’s very long-period groundswell, and the combined energy is a whopping 8411. The morning is clean with a light offshore wind from the west. But here’s the thing: Dee Why Point is an advanced break, and this swell is well over 8 ft. It’s too big for anyone but experts. The long period means it’s going to be powerful and lining up well on this point, but the size will make it seriously heavy. The afternoon drops to 12 ft, but the wind goes cross-onshore, so it’ll get messy. If you’re an expert, that Friday morning is the session to aim for. It’s still a week and a half away, so keep an eye on it, but it’s promising.
The following Saturday the 1st of August still has plenty of size, with a 10 ft south-southeast swell (period 11 seconds, energy 1922), but the wind is cross-shore from the south-southeast, so it’s not as clean. Sunday the 2nd of August morning sees another 12 ft south swell, but again, it’s too big for most.
So, to sum it up: the first week is mostly a slog with a few clean-but-small windows. The real action is the last week of July into early August, with that massive swell on the 31st being the highlight. But it’s for experts only. The water temperature is average for this time of year, so expect a normal winter wetsuit.
Rusty.
