*Sydney's score calculated to a 60.9% / D-, but climates where it has not snowed within a typical human lifetime (about 75-85 years) are capped to an E rating, the highest of which is a 59.4%. Since Sydney has not seen snow since 1836, this cap applies.
Sydney, but I wouldn't mind Sfax, although it's too dry for plants/vegetation.

Sydney. Sfax is desert garbage.

The "snow" in 1836 was said to be graupel, although it was 'recorded' and forecast as snow:

Most certainly not!
It very easily snows at 3° C or even slightly higher round here—especially beneath WSW/SW frontal systems.
The colonial settlers at the time would've certainly been familiar with a fall of snow; snow can fall at most peculiar places at times. Take, for instance, West Wallsend (70 m AMSL; 32° S, near Newcastle) in the winter of 1965.

I've heard of snow at 3C/38F and seen it, but it's typically light and doesn't stick. It's plausible that it snowed at that temperature, but heavy snow is nearly impossible that warm due to the dew point effect - if there's heavy precipitation at 3 C / 38 F, the dew point is probably above freezing, and it would be heavy rain, which I have seen a number of times in that temperature range.
This calculator shows that at 3 C / 38 F, it's likely (more than 50% chance) to be snow if the humidity is below ~65%. If the humidity is below ~54%, it's pretty much certain to be snow, at ~54-81% humidity, there is a diminishing chance of snow, and at 82%+ humidity it will NOT snow. Since precipitation typically falls at high humidities and precipitation below 65% humidity is fairly rare, it usually rains. Nevertheless, snow is still a possibility.
By the way, at 10 C / 50 F and 1% humidity precipitation would still be snow. But it would never precipitate at 1% humidity.
And as we can plainly see from Syndey's meteorological reports from 1836 (of which Ethereal had posted), the wind direction was chiefly SW; these sort of frontal systems yield rather dry and cold air for anywhere eastwards of the Great Dividing Range, thereby snowfall was quite a certainty for Sydney.
