The USA is vast, so rainy seasons vary by region. Florida and the Southeast have a pronounced rainy season from June to September. Hawaii's wettest months are November to March. California and the Southwest see most rain in winter (December to March), while the Northeast (New York, Boston) has fairly even rainfall year-round.
The best time to visit the USA depends on your destination. For most, spring (April–June) and autumn (September–November) offer pleasant weather and fewer crowds. Summer is popular but can be hot and humid in many regions.
