The best time to visit the US depends greatly on where you are visiting – the sheer size of the country means the weather varies greatly.
Generally, for a visit to the East Coast, April to October are the best months, though summer in New York can become quite warm and humid.
The best time to travel to the West Coast is between May to September, and the citiies of Los Angeles, San Francisco and Las Vegas can generally be visited all year round.
Hawaii is a tropical year-round destination, though October and November are hot and dry and not the best time for hiking.
The most popular time to visit Alaska is between April and August due to the favourable weather and accessibility around the state, and although it can be rainy from late-September, this is also when the northern lights begin to appear.
