I think the thing is that generally you can plan to have a day out and pretty much know that you will be able to do it without getting rained off. Having said that we came back from a beach walk today, soaked to the skin. But it was good, and cooled us off nicely.
It can get too hot up here in Central Queensland to be outside during the day, and yes, the mozzies do attack, but cover up, spray and burn stuff to keep them away, and the dark evenings can be fun. All the sports fields are lit and life still goes on even after dark, although QLD people do go to bed early and get up early!
Yes, I think we do spend more time outside, but it's not all day, every day.
