Sydney = which USDA hardiness zones?

[Mohsen]

It would be great if I could find the right equivalent for weather in Sydney according to USDA hardiness zones?10a, 9b ?

Depending on what part of Sydney, the coast/city would be zone 10, (possible that areas right by the water could be zone 11), with areas further inland zone 9

The use of the USDA system in Australia can be very subjective.........Generally speaking Sydney on a whole is probably similar to southern California but there are differences........ Whereas Brisbane is probably similar to southern Florida....... No doubt there would be some sheltered coastal positions in Sydney that would have warmer minimums than some Brisbane suburbs however those same Brisbane suburbs would be capable of growing a more diverse range of palms more successfully due to higher average temperatures, Coconut Palms are a classic example of this as they will grow in most Brisbane suburbs.

Thanks for the reply ...the problem I have is : as we moved to this property exactly a year ago I have only seen one winter...it was rather cold and some night -1 as well...but my neighbor said that he hasn't seen such a cold winter in 30 years so hopefully last winter was exception...I hope that we don't have any frost...another historical data shows that Sydney hasn't had any snow since 1830 so my guess is that it shows we had very rare minus temperature in winters...I don't think we could grow Coconut even in the warmest coastal suburbs in Sydney...

The issue is that I became a palm- lover after we bought this property , Otherwise I would take that into consideration to buy a property in a  warmer suburb

As your garden develops so too will microclimates so I probably wouldn't be too concerned, you will still have a wide array of gorgeous palms that you will have success with

Old thread, but Sydney ranges from 11a at the coast to as low as 9b in the areas lying on Blue Mountain's foot. Most of Western Sydney is zone 10.
