The best time to visit the US

High season in the USA

With a landmass covering 9.8m km², the USA is suitable for travel year-round – but the climate varies widely depending on the region you are planning to travel to. During the summer months of June-August, northern states are pleasantly warm, while the southern states and tropical areas can get very hot and humid. The fall season of September-November brings cooler temperatures and spectacular vistas in the northern states as the leaves turn red and orange. The winter is mild throughout the southern states, while the northern regions experience colder temperatures and snowfall, with regions such as Denver becoming popular ski destinations from November through to April.

Low season in the USA

Low season in the USA varies by region, given the country’s huge size. Northern destinations such as New York and Chicago can be very cold between January and March, but with many indoor attractions such as galleries and museums, it can be a good opportunity to avoid the crowds. Winter in the southern half of the country also brings fewer crowds – with pleasant temperatures between November and March in regions such as Florida. It’s worth noting that temperatures in desert regions drop significantly at night during the winter months – so remember to bring warm clothes!
