United States: when to go?
continental modéré climate
The United States offers exceptional climatic diversity, but flagship destinations like New York, Washington, and the East Coast experience a moderate continental climate with four well-defined seasons. Summer (June-August) is hot and humid with temperatures often exceeding 30°C, while winter (December-February) can be harsh with snow and below-freezing temperatures. Spring (April-May) and fall (September-October) are the best periods to explore these regions: pleasant temperatures between 15 and 25°C, moderate rainfall, and stunning autumn colors. These intermediate seasons allow you to fully enjoy city visits, national parks, and outdoor activities without enduring extreme weather conditions. For optimal travel, choose May-June or September-October depending on your preferences.
