Hi Meditator,
Bit of an open ended question.
Firstly the weather, yes it will be warming up by October, and depends on how much rain we have to how sticky it can get here. (yes, there are uncomfortable days because of humidity, even in the desert.) Check the
www.bom.gov.au to see what the average temsp are. Winds are south easterly a large perscentage of the time.
Given this is a bicycle forum, I assume you will be travelling by bike. Check out the road to Glen Helen Gorge, as it is all sealed. Glen Helen has a small pub with a camping ground, about 120km west of Alice, on the bank of the Finke river (dry). You also pass Ormiston Gorge, and can stay in the Ormiston camping ground area, as it is a park. Great swimming, fantastic Ormiston Pound walk.
You can go further out on the same road to Tylers Pass and on to Gosse Bluff, with about 30km of dirt road to traverse. No water from Glen Helen onwards.
A few art galleries in town, with nice prices. Are you talking about dot painting or lanscape paintings?
To give more advice, best to know more on what you want to do.
cheers

PS the rock is 480km from Alice, and has road houses along the way.
