Spring/early summer.
I live in a resort town in Arizona so its dead in terms of social events in the summer and it was too hot out in the summer too. I almost never lay out at the pool. it is too hot and I do not need the sun exposure.
a couple good perks about the summer in Arizona:
staycations. I will usually get a hotel on a random weekend at a nice resort for cheap. Next week is Labor Day so I will find a cheap deal on a hotel and do a weekend stay. I did that for the 4th of July this year. I would like to get away/out of town but a nice weekend at a resort is pretty money
golf - you can play premium courses for cheap since there is little demand
its hot so it forces to me go to Cali, go into the mountains in Northern AZ on weekends r
Springtime in Scottsdale, AZ is the best mainly due to the social events:
MLB Spring training baseball
all the good concerts in town are in the spring
Barrett Jackson cat auction (all kinds of car events that week)
Arabian Horse show
PGA tour event
Arizona state baseball games (Sun Devil here

)
hot chics and hotel pool parties
restaurant week
great hiking/sunrises
aint shit going in the summer lol - tumble weeds and expensive AC bills.
I grew up in Chicago so ive done enough winters -
