January is deep winter across much of the United States. Expect very cold temperatures in New England, the Midwest, and the Mid-Atlantic states. You can also expect cold weather in states in the Southeast and Southwest, though temperatures are typically milder here than in the North and Midwest. Temperatures usually are connected to altitude, with destinations at higher elevations being colder. For mild temperatures, head to Hawaii, Arizona, or Florida.
No matter what you’re looking for, the United States has plenty to offer in January. Whether you’re hitting the slopes, escaping the cold, or just looking for an amazing vacation, you have tons of options. Take your pick.

What to Pack
Packing is dependent on where you will be going and, of course, the weather and the activities you plan to do. In general, the south and west are more casual than the northeastern states. Cities will give you more opportunities to dress well (at least business casual) than in rural areas. The following tips may be something you haven't considered:
- You'll need a hat, no matter where you go. If its sunny a had can shield you from the heat and glaring sun. If it is a cold place, you'll need a hat because you lose the most body warmth from your head.
- Sunscreen is needed for both skiing and boating.
- Except in resort areas, darker clothing is best for the season.
- Weatherproof jackets and shoes are ideal for places where it may rain, snow or be foggy like San Francisco, New York City, and New Orleans.
- Layering is always ideal whether it be under a warm coat for colder climates, or a light jacket for warmer climates. Even in the desert, you'll need a jacket for evenings as it cools down fast.
- Walking shoes and footwear for sports you intend to participate in are must-pack items for January travel.
January Events in the United States
In the United States, the big winter holidays are celebrated in December, so January can be a time when there are not too many holidays to affect your travel plans.
- January events kick off with New Year's Day festivities such as the Tournament of Roses Parade in sunny Pasadena, Southern California, near Los Angeles.
- The world-famous Sundance Film Festival takes place in snowy Park City, Utah.
- Martin Luther King Jr. Day is an American federal holiday marking the birthday of Martin Luther King Jr., civil rights leader. Many businesses and government offices are closed. MLK Day is observed on the third Monday of January each year. Many people get out and do volunteer work on this day in honor of Dr. King.
Activities and Events For Snow Lovers
If you have a magical Winter Wonderland vacation in mind, there is no place like New York City. Fifth Avenue offers beautiful holiday window displays in the biggest department stores. Snow-covered Central Park is filled with horse-drawn carriages and Christmas lights. And of course, if you’re in New York during the first week of January, the Rockefeller Christmas Tree lighting is a holiday tradition not to miss.
New York in the winter is definitely chilly but it’s not quite as extreme as some other U.S. cities because it's on the coast and the temperature is regulated by the ocean. Boston and Chicago are two popular destinations in the United States that have colder weather, thanks to the latter being located north and the former in the west away from the ocean air. Both cities average below 36 degrees during January and both get much colder at night. If you’re planning a trip to one of these cities in January, prepare for low temperatures and dress warmly!
If you are looking to get away for a weekend at the slopes, there are many ski destinations to pick from. Colorado is a popular place for a ski getaway, with Aspen, Steamboat Springs, and many other mountains; you’ll have your pick of locations! Utah is another popular place to ski with several famous mountains to choose from. If you’re more interested in a ski trip on the East Coast, Vermont is the place to go.
Activities and Events For Beach Lovers
If you’re looking for a sunnier, milder place to visit in January, there are many cities to check out: Las Vegas, San Francisco, Los Angeles, and New Orleans are some popular destinations. Las Vegas offers many indoor activities with all of the famous concerts and shows to check out (and, of course, gambling!). San Francisco’s weather tends to be pretty mild throughout the year so any time is a great time to visit. L.A. is known for its sunny weather, but if you’re looking to avoid the extreme heat, January is a really pleasant time to visit.
New Orleans is another popular destination to explore during the winter because humidity levels drop, the weather tends to be milder and visiting the famous city before Mardi Gras is a way to avoid the crowds.
Hawaii and Florida are also postcard-worthy places to get away from the cold in January. With temperatures averaging in the 70s and 80s, they are the perfect place to escape all that snow. With beautiful beaches, a plethora of theme parks, and incredible natural beauty, you really can’t go wrong with a trip to these destinations.
Activities and Events For Desert Lovers
Another warm-weather destination is the desert of Arizona, Southern New Mexico, and Nevada. January is a month where "snowbirds," retirees from the northern states who spend extended time in the warmer climates of Florida and Arizona, will flock to the desert to stay in RV's, vacation homes, resorts, and condos. Favorite winter activities are golf, hiking, Spring Training Baseball, and relaxing around the pool.
January Travel Tips
January travel can present some challenges.
- In warmer climates, January, after the December holidays have passed, is a time that retirees head for their winter retreats in Florida and Arizona, especially. It is a time when vacation rentals and resorts are very busy.
- If you are flying in or out of airports in the northeastern United States, pay particular attention to the weather. Snowstorms can blanket areas shutting down road and air transportation.
- In some areas, since the holidays have passed and children have returned to school, January is seen as a shoulder season and prices in places like Santa Fe, New Mexico and ski resorts can be lower.
