When I moved back to Australia I chose to live in Brisbane because of the great weather.
There are a few quirks though.
The height of summer is from Christmas. Summer is generally not hot when compared with southern cities, often with the temperature lying between 30-35 degrees, you have all the advantages of life in the tropics without the killer humidity (I grew up in North Queensland).
The worst part of summer is that from about Christmas onward it tends to rain nearly every day, even if it is just a short shower. The first year back from abroad it seemed to be sunny from Monday to Friday and rain on the weekends.
Yet it is rare that Brisbane has a full day of rain, meaning you easily plan outdoor activities even if the forecast is for showers. Often when there is a forecast of rain there is no rain or it only rains in certain parts of South East Queensland.
Summer is the time of the year that people head to the beach or the mountains to take the edge off the heat.
Autumn manages to arrive with a rush around May when we will suddenly have a cold snap. Which is good because it takes us from summer mode into winter mode even though the temperature usually comes back to the mid 20s for rest of May and June. This is when people start become interested in outdoor activities other than the beach, in particular hiking.
July tends to be cold, though it can vary. I like the fact that my friends from the Northern part of the world contact me and say "It is winter in Australia now, what is the temperature like?" Then I get to reply with "A bit cold today, around 20 degrees". They usually think I mean -20 degrees but I manage to correct this mistake to cries of disbelief.
Winter's main hassle is that some days it will be in the mid 20s and other days it will be between 15 and 20 degrees making it hard to plan too far ahead. Yet it is a great time for a whole range of outdoor activities. Also I can't seem to find a single pub that has a good winter beer on tap, definitely it is a summer mind set all year round.
It is rare to see a day in winter cold enough not to see somewhere out and about wearing t-shirt, shorts and thongs (flip-flops for people from other countries reading this).
When Spring arrives Brisbanites are reluctant to shrug off the Winter mindset until the sudden urge for barbecues and the beach hit them and the feeling of summer takes us all.
Abandoning the old 4 season mindset of cold climates, my favourite and least liked seasons are
Jacaranda Season: comes in September and lasts until early November and is accompanied by the Flame Trees coming into bloom as well.
Dry Season: When it isn't raining every day I feel better, no matter how cold it gets.
Wet Season: Is more annoying than anything else though some years it can be damaging downpours and floods.
Footy Season: Is the worst because Brisbanites starved of any entertainment flood the streets in team colours. In all codes I support teams from other states.
Spring is amazing in Brisbane - the perfect weather for exploring the outdoor parks, bikeways, and walking tracks about town. The jacaranda trees can be spotted across the city in September/October and it is great to play in all the fallen blossoms which create a magical purple carpet along the roads and footpaths.
