North America in March: Weather, Crowds & What to Expect

Arctic & Subarctic (Northern Canada, Alaska, Greenland)

By March the light increases sharply and conditions begin to feel more energetic: sledding, ice‑fishing and winter festivals continue while approaching spring produces firmer sea-ice for coastal travel. Anchorage and Whitehorse still experience snow but daytime hours lengthen, making exploration of towns and nearby ranges more comfortable. Ski resorts in Alaska and interior Canada are still in full swing, while aurora viewing remains excellent in clear, cold nights.

Pacific Coast & Western Mountains (Pacific Northwest, British Columbia, Yukon south, California coast, Cascades, Sierra, Rockies foothills)

Early spring transition in March finds clear, crisp days mixed with late storms; Vancouver’s rain lessens occasionally and lowland wildflowers start to appear around Victoria. Ski lifts remain open in higher resorts, while melting in lower elevations creates muddy trails in places like the Columbia Gorge. California’s coastal hills bloom in sheltered spots; pack layers for cool mornings and sudden rain showers.

Southwest US & Northern Mexico (Baja California, Sonoran & Chihuahuan Deserts, Arizona, New Mexico, northern Mexico states)

March ushers in warming conditions and popular spring-break crowds in parts of southern California and Baja; cities like La Paz and Los Cabos become lively as boat and whale-watching tours operate strongly. Inland deserts warm quickly - day hikes into Saguaro or Organ Pipe areas become appealing but carry ample water and sun protection. Mountain passes retain snow at high elevations, offering a cool contrast to the desert heat.

Great Plains & Midwest (Canadian Prairies, US Plains & Midwest: Saskatchewan, Manitoba, North Dakota, South Dakota, Nebraska, Iowa, Illinois, Minnesota, Wisconsin, Missouri)

By March the pattern shifts toward transition: days lengthen and severe-weather setups begin to appear, especially in the southern Plains and Midwest where late-season snow may alternate with the first thaw. Early spring can also bring the first severe thunderstorm outbreaks and tornado risk in places such as Oklahoma and central Kansas. Pack for volatility: waterproof layers and warm clothes for cold snaps, plus an eye on severe-weather watches.

Northeast & Atlantic Canada (New England, Quebec, Newfoundland & Labrador, Nova Scotia, Prince Edward Island, New Brunswick)

March brings the first hints of spring while nor’easters can still deliver heavy coastal snow and flooding: St. John’s and Halifax see variable conditions with mix of snow and rain. Inland trails start to thaw and the mud season begins in late March in some areas of Atlantic Canada; plan footwear for sloppy conditions. Shoulder-season travel offers lower prices but bring waterproof layers and flexible connections.

Southeast US, Gulf Coast, Caribbean & Central America (Florida, Gulf states, Yucatán, Belize, Guatemala, Honduras, Nicaragua, Costa Rica, Panama, Greater Antilles, Lesser Antilles)

Warm, busy travel signals March as spring break peaks: Florida beaches, Cancún and popular Caribbean islands become frenetic with warm days and low rainfall. Inland Central American locations remain comfortable; Nicaragua and Costa Rica’s Pacific coast are dry and hot. For calmer experiences, opt for highland cloud-forest treks in Guatemala or Costa Rica, and make reservations early for popular coastal spots.
