Coastal California is typically cooler than all of the states you mentioned in summer and warmer in einter. The other states have their own homeless populations- even Minneapolis get encampments that last into winter- but none are as favorable to outdoor survival and comfort as the southern Pacific Coast. Also, california spends much more than all of the other states on providing assistance to the homeless, and is far more tolerant of bad behavior (public drug use, drunkeness, defecation, etc). California isn't bad at handling the homeless so much as it is bad at getting the homeless to become housed, mentally and financially stable.
