It depends on what you are allergic to, how long it takes you to become sensitized to something new.
I grew up in southern Michigan, my allergies were to what was growing there. In summer we could get away from most of those allergens by going to the U.P. or the northern parts of the L.P. Going south into corn country, they just got worse.
Twelve weeks in San Antonio, either my Michigan allergies were still acting up or my fellow trainees kept reinfecting me with rhinoviruses. Two years in coastal Carolina I was mostly symptom free, two years in Indianapolis got me back into allergy country. Then in Central Florida, I was symptom free for the first year but before the end of the second I had been sensitized to Florida pollens and molds.
The usual problem in Arizona is that all the migrants from the Midwest and Northeast have brought their favorite ornamental plants with them, in that climate they just need watering. When you get into the frost-free parts of Florida, a lot of the northern plants don't do well, so you are mostly dealing with a new flora, exposing yourself to mostly new allergens. It takes a while for your overactive immune system to respond, but eventually it will.
