High / low are average daily temperatures (°C). “Feels” reflects how hot or cold it feels, allowing for humidity.

Northeast (New England & Mid‑Atlantic)

March tends to feel like a handoff from winter to spring: coastal winds keep Boston and Providence brisk while inland valleys see mud and melting snow. Early spring festivals start to pop up (St. Patrick’s events in NYC, maple sugaring in Vermont), and the season’s first good hiking days often follow late‑month warm spells. Bring layers-thermal base layers plus a waterproof shell-and be prepared for travel rescheduling around nor’easters that sometimes form this month.

Southeast (Carolinas, Georgia, southern Appalachians)

March sees rapid warming and the start of spring festival season-Azaleas in bloom at the Charleston Spring Festival and dogwoods along Blue Ridge trails-while lowland areas can be humid. Severe‑weather season edges closer; occasional strong storms and tornado outbreaks are possible, especially in the western Carolinas and Georgia’s interior. Travelers should carry a light rain layer and be mindful of flexible plans if attending outdoor events.

Florida & Gulf Coast (Florida peninsula, Gulf beaches, Tampa Bay, New Orleans area)

March signals warming-Orlando heats up for spring breakers and coastal towns begin to feel summery-while precipitation stays relatively low across most of the peninsula. Theme parks run busy; if you’re avoiding crowds aim for weekdays and book fast‑pass options. For beachgoers the water is warming; bring reef shoes for rocky stretches and be alert for occasional red tide advisories along the Gulf.

Midwest & Great Lakes (Chicago, Detroit, Minneapolis, Great Lakes shoreline)

March begins a slow thaw; in Michigan and around the Great Lakes expect slushy roads, slushy sidewalks and dramatic swings between cold snaps and milder spells. Early spring events pop up-St. Patrick’s festivities in many Midwestern cities-and lake ice breaks can lift spirits but complicate boating schedules. Bring waterproof shoes for wet conditions and be prepared for muddy trails as snowmelt feeds swollen rivers.

Great Plains & Central US (Kansas, Nebraska, Oklahoma, Missouri, parts of Texas Panhandle)

March signals the approach of severe weather season-temperatures rise and the region becomes volatile with storms, hail and the first tornado outbreaks of spring. Spring travel should include awareness of weather shelters and local siren systems, especially if road‑tripping across sparsely populated routes. Warmer afternoons are good for early agricultural festivals and farm‑to‑table events; pack a small emergency kit just in case.

Rocky Mountains & Intermountain West (Colorado, Utah, Wyoming, Idaho, Montana foothills)

March starts to feel transitional: spring storms alternate with sunny, bluebird days and variable conditions make melt‑freeze cycles common at lower elevations. Ski resorts still operate at higher altitudes, and spring skiing festivals begin; pack layers for both icy mornings and warm afternoons. If you’re road‑tripping, check mountain pass conditions-mud and snowmelt can make some scenic drives messy.

Southwest (Arizona, New Mexico, Nevada deserts, southern California inland)

March heats up in the low deserts-Tucson’s spring festivals and Phoenix’s outdoor events fill calendars-while windier conditions can create dusty days in open basins. In southern Nevada (Las Vegas) this is an enjoyable month with warm days and comfortable nights, though high‑traffic events often push hotel rates higher. If visiting the Grand Canyon, spring winds at the rim can be strong-pack a windproof layer.

Pacific Coast & Pacific Northwest (California coast, Oregon, Washington, coastal national parks)

March starts to green the hills: wildflowers in California’s coastal ranges can bloom early in warmer years, and the Cascades begin to see spring snowmelt and avalanche risk at elevation. Roadside waterfalls along the Oregon coast become impressive and whale‑watching ramps up from several headlands. Pack layered clothing for chilly mornings and watch for spring break crowds at popular coastal parks.
