Where to Find Warm Weather in the USA in March: at a glance
Prioritise southern Florida and the Keys for the most consistent warmth and ocean-adjacent activities.
Head to the Sonoran Desert in Arizona for dry, sunny afternoons perfect for hiking and outdoor exploration.
Choose the Gulf Coast of Texas or Louisiana for a mix of urban culture and coastal access before the humidity of later months arrives.
Anticipate cooler evenings regardless of the location, as inland and desert regions often experience a significant temperature drop once the sun sets.
How to choose a warm-weather trip in March
Selecting a warm destination in March involves balancing the desire for heat against the practical realities of the lingering winter season. While the southern states are warming, the term "warm" is relative; you will find comfortable, sun-drenched afternoons in the deserts or on the coast, but evening layers remain a necessity almost everywhere.
It is helpful to decide whether your goal is water-based activity or dry-land exploration. If your priority is swimming in the ocean, look to the southernmost reaches of Florida, as water temperatures in the Gulf of Mexico and the Atlantic remain brisk throughout the month.
If your goal is desert hiking or city walking, the American Southwest offers a sweet spot of temperate days that avoid the extreme heat of the summer, allowing for long hours of comfortable movement.
Eight warm-weather destinations for March
1. The Florida Keys
The Florida Keys provide arguably the most reliable warmth in the continental United States during March. As you traverse the Overseas Highway, you are surrounded by the Atlantic Ocean and the Gulf of Mexico. This is a time when the islands are busy, yet the climate remains pleasant rather than stifling.
You can spend your days snorkelling in the shallow reefs of John Pennekamp Coral Reef State Park or wandering the historic streets of Key West. The proximity to the water keeps the air feeling fresh, and the island lifestyle encourages a slower pace.
Because this is a popular month for travellers, expect a lively atmosphere across the various keys, with plenty of opportunities to sample local seafood.
2. Tucson, Arizona
Tucson serves as an ideal base for those who prefer dry, arid warmth over coastal humidity. In March, the Sonoran Desert is often in a state of quiet transition, with the potential for early-blooming wildflowers and cacti.
The city provides direct access to Saguaro National Park, where you can walk among thousands of the namesake cacti against a backdrop of mountain ranges. The temperature in March allows for extended time outdoors during the middle of the day, making it an excellent period for cycling or exploring the historic missions that dot the region.
The city’s cultural districts are highly walkable, offering a mix of architecture and local cuisine that reflects the intersection of regional histories.
3. Savannah, Georgia
By March, the squares and historic districts of Savannah begin to shake off the final traces of winter. While not as hot as the tropical latitudes, the city experiences a pleasant, mild climate that makes walking the moss-draped streets and riverfront paths deeply enjoyable.
This is a time when the azaleas often begin to bloom, adding colour to the historic parks. You can spend days exploring the various museums, riverfront warehouses, and local markets without the intense heat that characterises the late spring and summer months.
The city’s compact design makes it easy to explore on foot, and the mild air allows for outdoor dining and evening strolls along the city’s many public squares.
4. Palm Springs, California
Palm Springs is a quintessential desert destination that thrives in the March climate. The basin is shielded by mountains, creating a pocket of warmth that is perfect for those looking to escape the lingering cold elsewhere.
Beyond the mid-century modern architecture and the downtown shopping areas, the town provides immediate access to rugged desert terrain. You can take the aerial tramway up to the mountain stations for a change in perspective or explore the hiking trails of the nearby Indian Canyons.
The air is consistently dry, and while the mornings can be crisp, the afternoons are typically dominated by sunshine and warmth, making it a reliable spot for poolside relaxation.
5. New Orleans, Louisiana
March in New Orleans brings a sense of energy as the city enjoys temperatures that are generally comfortable for walking through the French Quarter and the Garden District. The humidity of the deep south has not yet reached its peak, making it an ideal window for exploring the city's unique blend of architectural styles and outdoor courtyard spaces.
You can spend your time touring historic cemeteries, visiting local markets, or simply enjoying the music that spills out from the clubs along the streets. The city’s parks, such as City Park with its ancient oaks, provide a sense of space and natural beauty that is particularly refreshing under the March sun.
6. San Antonio, Texas
San Antonio offers a compelling mix of history and riverfront urban design that works well in March. The famous River Walk is a central artery for exploration, allowing you to move through the heart of the city while remaining in a sunken, lush environment.
The weather is typically gentle, which is a major advantage when visiting the various historical sites, including the mission complex at the city's centre. Exploring the nearby botanical gardens or the historic Pearl District is particularly pleasant before the Texas summer heat arrives.
The city feels open and inviting during this month, with a steady flow of visitors contributing to a lively but not overwhelming atmosphere.
7. St. Augustine, Florida
As the oldest continuously inhabited European-established settlement in the continental United States, St. Augustine provides a unique historical backdrop for a March getaway. The coastal location ensures a moderate climate, perfect for walking the narrow, colonial-era streets of the old town.
You can visit the massive masonry fort that guards the harbour or take time to walk the local beaches. While the Atlantic water might still be on the cooler side for swimming, the weather is consistently conducive to sightseeing and outdoor exploration.
The city has a distinct character that feels different from the glitzier parts of Florida, making it a great choice for those interested in heritage and architecture.
8. Death Valley National Park, California
For travellers who want to experience the dramatic landscapes of the desert without the lethal heat of summer, March is one of the best times to visit Death Valley. The valley floor remains comfortably warm, allowing for safe exploration of iconic locations like the salt flats at Badwater Basin or the colourful formations at Artists Palette.
Because the elevation changes significantly within the park, you can often find cooler temperatures by driving to higher points like Dante’s View. It is a stark, vast environment that feels entirely removed from the rest of the world.
Ensure you have ample supplies and a vehicle in good working order before heading into these remote areas.
Planning your March trip
When planning a trip to a warmer climate in March, the most important consideration is the difference between air and water temperatures. Do not assume that warm air equates to swimmable ocean water; if your heart is set on swimming, stick to southern Florida or be prepared for brisk conditions.
Packing should focus on layers. Regardless of how warm the afternoons are in places like Tucson or Palm Springs, the temperatures will plummet as soon as the sun goes down, so bring a light jacket or fleece.
For city trips like New Orleans or Savannah, comfortable walking shoes are essential as these places are best discovered by wandering through their various districts. If you choose a desert destination, remember that the sun is strong even when the air feels moderate, so hats and sunscreen are mandatory daily companions.
Frequently asked questions
Which is warmer: the California desert or the Florida coast?
The Florida coast generally offers more consistent warmth in March, particularly as you move further south toward the Keys. The California desert, such as Palm Springs or the Mojave, offers pleasant, sunny days, but the temperature difference between day and night is much more pronounced than in Florida.
Is the water warm enough for swimming in March?
Ocean swimming in March is generally limited to the southernmost points of Florida. In most other coastal locations in the USA, including the Gulf Coast and the northern Florida beaches, the water temperature remains quite brisk. Always check local conditions before heading to the beach with a swim in mind.
Will I encounter crowds in these warm destinations during March?
March is a popular month for domestic travel, particularly during school spring break periods. Destinations like the Florida Keys and major desert resort towns often see an increase in visitors.
You can often find quieter moments by staying slightly outside of the central tourist zones or visiting attractions early in the morning.
Is a rental car necessary for these trips?
In desert destinations like Death Valley or around Tucson, a rental car is essential for exploring the vast landscapes. In cities like New Orleans, Savannah, or the historic core of St. Augustine, you can often manage with walking and local transport, though a car provides more flexibility for reaching outlying natural areas.
Are the national parks in the desert fully accessible?
Most desert national parks are open and fully accessible in March. This is a peak time for visitation due to the temperate weather. However, always check the park’s official website for any specific area closures or road maintenance projects that might affect your planned route before you set out.
Should I pack heavy clothing for a March trip to the south?
You do not need heavy winter gear, but you should absolutely bring layers. A lightweight windbreaker, a medium-weight sweater, and trousers are necessary for almost all these destinations. The evenings in the desert and the early mornings in the south can feel surprisingly chilly once the sun is no longer active.
How does March weather compare to April?
April is generally warmer than March across the United States. While March is a transition month where the weather can still swing, April typically sees more stable, consistent warmth and a higher likelihood of fully blooming landscapes. If you prefer higher temperatures, April is often the more reliable choice.
Are there specific festivals to watch for in March?
Many cities hold cultural or music festivals in March to celebrate the return of spring. Because these events often shift dates, it is best to check the local municipal or tourism board websites for the destination you choose. Expect that accommodation in those cities may fill up quickly during major festival weekends.
Final thoughts
For those seeking a reliable escape from the cold, the Florida Keys provide the most consistent warmth for a coastal stay, while the desert landscapes of Tucson or Palm Springs are ideal for those who prefer dry, sun-filled days. Choose your destination based on whether you prefer the maritime charm of historic coastal towns or the expansive, rugged beauty of the desert.
