When Is The Florida Migration At Its Peak?

My dad is in his 4th year doing the snowbird thing and has settled into a mid-October to early May pattern. This 6 month minimum has allowed him to change his residency to FL along with it’s associated benefits vs NY. His condo complex remains at about 50% occupancy until after the holidays. NOW is the peak snowbird period as owners will continue to pile in over the next 10 days. Nearly all will be gone by May 1. The limits on our Canadien friends are a nuisance for most.
