This only looks at one dimension: temperature. There are other dimensions to look at:

- Humidity, or rather: Dew Point. 22ºC / 72F feels awesome or nasty depending on whether dewpoint is 10ºC or 21ºC. Anything above 16ºC is generally unpleasant.

- Sunshine. Many overcast days can do a number on our well being, but some people actually prefer the softer light.

- Rainfall. Some prefer more on the dry side, others more on the lush side. Again, it's a personal preference.

- Variety throughout the year. Some of us actually enjoy the diversity of seasons while others prefer constance.

I'd add UV to the mix - i.e. Auckland climate is great, but on sunny day you generally stay away from it.

That's true of any place in the Southern hemisphere though.
