I live here year-round, and nowadays (as opposed to the 80's and early 90's) there is very little difference in the traffic and number of people in the restaurants, grocery stores, shopping centers, etc. throughout the year. Used to be that you'd get the annual influx of snowbirds from November through February, and the spring breakers in March, but other than that, it was pretty deserted from Labor Day until Memorial Day. That is definitely no longer the case.
