No. 3: Utah
Strengths: Good health care, weather
The Beehive State -- which claimed the No. 3 spot in last year's rating, as well -- scored above the national average all around, getting particularly good marks for low cost of living, comfortable weather and good health care.
Utah has the sixth-best weather in the nation, thanks to its dry climate and clear, sunny skies. It's also one of the most affordable states in the country. The state's health care system is also top-notch, ranking seventh-best in the country, according to the Agency for Healthcare Research and Quality.
Another healthy piece of news for retirees looking to live in Utah: The state saw relatively few elderly residents admitted to the hospital for the flu, suggesting immunizations are widely distributed to the 65-and-older crowd. Utah also has fewer diabetes-related hospitalizations than many other states and a lower cancer rate.
