Weather InformationWeather in Connecticut is less extreme than in other parts of New England, with an average of only nineteen days reaching above 90 degrees and only six falling below zero degrees.
Crowd InformationThe state offers many festivals and events throughout the year that may attract crowds. New Haven's sixteen-day International Festival of Art and Ideas in June fills the city with music, poetry, opera, dance, and art events. Also, there tends to be more crowds during fall foliage season.
Closure InformationMany of the amusement parks close after Labor Day and reopen before Memorial Day. During the winter, campgrounds and parks are liable to close due to adverse weather conditions.
When to SaveMidweek travel deals are a fairly reliable way to save money.
