The USA has varied seasons in each of its regions, but in general, the best time to visit the USA during Spring and Fall, however Summer months from May to September are considered the peak time for tourists to visit the country. Spring generally lasts from March to May as it is a beautiful season for most of the country. It is the best time to visit heritage sites and a great time for outdoor activities like hiking, biking, and camping because of the varied terrain. Spring comes a little late in places of Northern USA. Another favourable season is the Fall from September to November. This is the time when the country celebrates the Harvest season and the weather is pleasant. Mountain driving, camping and rock climbing are the most enjoyed activities by tourists. The summer months, on the other hand, could bring a really hot and humid temperature to the country although it's considered the peak tourist season. It is an ideal time for beaches and exploring nature. The hurricane season hits the USA during August and September which is not a good time to visit the country. Another time that could be horrendous is in December during the snowfall which lasts until February. The winter season is generally an offseason to visit the USA. However, visiting the country during Christmas and New Year's Eve could be a different experience.
