Sure.
No significant elevations or topographic noise would mean free way for persistent continental northerly winds to reach Sydney –not VERY continental as the trajectory of the air mass wouldn’t go through a lot of landmass-, but enough to bring a lot of sunny 31-33C days. Yes, there would be a lot of Northeast too, plus the breeze lurking around and the sporadic cold fronts which would help activate convection and cool down temps. So I can imagine some 20/27C summer averages becoming something like 20/29C.
OTOH, there would be also free way for winds from the Southwest to bring some interesting winter lows, so I can see winters being a bit cooler too. We can’t expect a mid-low latitude spot exposed to a lot of land to the west to keep an annual range of just 10 or 11C.
Actually, yeah, now I see what you mean. Hotter, more stable summers (but with far milder records) defo sounds likely. Kinda like Adelaide but with wetter and milder summers. |

Maybe if you explained it like Marcelo did (i.e., with proper non-Swedish English tsk tsk)…there wouldn't have been much confusion. At the start of the argument, you were acting like the whole year would get warmer without the GDR. So, like, don't even try. |

What makes you think it'll get hotter summers without the GDR? Explain yourself thoroughly.

I did think of that, considering that no mountains would be in the way to hinder hot and dry north-westerlies. But at the same time, I had thought that the Ranges naturally warm things up towards their slopes, hence the hotter records in far western Sydney than those in the middle of NSW (where no mountains are "covering" them from the desert heat). So maybe the extreme heat in the far west could be UHI related? P.S. Winters would definitely be wetter and colder for sure. This is unequivocal. |

It's got nothing to do with those northwesterlies, but rather the fact that localised sea-breezes wouldn't be as effective anymore without the GDR; those cooler, cloudier 23° C summer days would become sunny 28°–30° C days, as the northwesterlies dominate over easterlies. But the record high would be no greater than 42° C at most, so a lot more "boring". |

And will southerly busters become reduced or "milder" without the GDR? Since you say that cloudy 23C days will turn into sunny 28C days. I wonder how wet and stormy summers/early autumns would be too. (If that's the case, then Sydney will become a quasi Mediterranean climate with longer, very wet winters and it wouldn't be as bad as my hypothetical one in this thread - So maybe I should revise my climate table  ) |

At the start of the argument, you were acting like the whole year would get warmer without the GDR. So, like, don't even try. There's nothing wrong with my English. Maybe you should work on your reading comprehension. "The desert is hot, the ocean is cool"; if in winter the ocean is warmer than the desert then whatever. My argument applies whenever the desert is hotter than the ocean. I've also only brought up summer temps in my examples anyway. But whatever, I really don't wish for this to become the start of another discussion/debate. |

Here is the revised climate table:  Summers are drier, sunnier and warmer (assuming that seabreezes won't be that significant). Winters aren't that rainy, but still rather wet and gloomy-ish. |

Probably not a realistic GDR-free Sydney, but those average highs and lows merit an A. Rainfall isn't that bad considering the sunshine levels (US West Coast perspective)

B+, equal to the current Sydney IMO. The near-perfect summer are however, partly let down by the mild, cloudy wet winters with lots of Failbourne weather.
