Climate and Temperatures
Best time to travel / Season
Miami and Miami Beach are very popular during winter and especially at Christmas.
In summer the beaches get crowded, but that's why people come: people watching.
In summer expect an high humidity which influences the human sense of heat. Watch the published so-called 'Heat-Index' which reflects the actual temperature and how it is felt by humans, which is higher.
Example: if we have an actual temperature of 30C you might feel if it were 36C.
During winter bring always some warmer clothes and a jacket. Especially the evenings and nights can get a little colder.
