What to Pack for United States
Complete packing checklist tailored to United States's climate and culture
Climate Overview
The United States has a diverse temperate climate with significant regional and seasonal variations. Generally, expect warm summers (70-90°F/21-32°C) and cold winters (20-40°F/-7 to 4°C), with spring and fall offering mild, transitional weather. Precipitation varies widely, from dry Southwest deserts to the rainy Pacific Northwest. Packing requires a layered approach, as temperatures can swing dramatically between day and night, especially in mountainous regions or during shoulder seasons. Always check the specific forecast for your destination, as the US spans multiple climate zones from Florida's humidity to Arizona's arid heat.

Luggage Recommendation
For most US trips, a carry-on sized spinner suitcase (22") paired with a personal item/daypack is ideal. This avoids checked bag fees on domestic flights and makes navigating large airports, public transit, and hotels easier. If visiting multiple climates or on an extended trip, a medium checked bag (24-26") may be necessary. Due to long walking distances in terminals and cities, prioritize luggage with smooth-rolling wheels.
