How Rainy Is March in Atlanta?

March is often a moderately wet month:

• Expect several days of light to moderate rain
• Some systems bring heavier showers and localized downpours
• Rain can be on-and-off during the day rather than all‑day washouts

You’ll want to keep an umbrella or light rain jacket available, especially if you walk, bike, or use MARTA around downtown and midtown.

Thunderstorms and Severe Weather Potential

Atlanta begins to shift into its spring thunderstorm season in March:

• Isolated thunderstorms can develop, especially as warm fronts move in
• Some storms bring gusty winds, heavy rain, and frequent lightning
• On occasion, March can see stronger storms across North Georgia

For local severe weather updates, residents and visitors typically rely on:

  Recorded forecast line: (770) 486‑1133

• Local TV and radio stations for real‑time alerts

If you’ll be spending time outdoors around Piedmont Park, the Atlanta BeltLine, or Stone Mountain, it’s smart to check the forecast before you head out, especially on warm, humid days that follow a cooler spell.

Humidity Levels

Humidity in March is usually noticeable but not oppressive:

• Cool mornings can feel crisp or slightly damp
• Afternoon humidity rises on warmer days but is generally comfortable
• It’s nowhere near the heavy humidity of late spring and summer

Light, breathable layers usually handle both temperature and humidity shifts well.

What to Wear in Atlanta in March

Planning your wardrobe for March in Atlanta is all about flexible layering.

Everyday Clothing Tips

Consider packing or wearing:

• Base layers: T‑shirts or lightweight long sleeves
• Top layers: Cardigans, light sweaters, or casual button‑downs
• Outerwear: A light to medium‑weight jacket or windbreaker
• Bottoms: Jeans, chinos, or other mid‑weight pants; some days can work for lighter fabrics
• Shoes: Closed‑toe shoes or sneakers that handle occasional puddles

Locals often start the day in a jacket and long sleeves, then shed layers by lunchtime once the sun comes out.

For Evenings and Early Mornings

Even in late March, sunrise and late‑night outings can be cool:

• Keep a warm layer (fleece, thicker sweater, or lined jacket) handy
• If you’re planning rooftop bars, outdoor concerts, or night games, expect temperatures to feel a full 10–20°F cooler than mid‑day

For Visitors Coming from Colder or Warmer Climates

• If you’re arriving from a colder northern climate, March in Atlanta will likely feel mild to warm, but don’t underestimate the cool, damp mornings.
• If you’re visiting from a tropical or very warm climate, you may want heavier layers than you think for evenings and rainy days.

Outdoor Activities and Events in March

March is when Atlanta’s outdoor life really starts to wake up, as long as you keep an eye on the forecast.

Parks, Trails, and Neighborhood Strolls

Common places Atlantans enjoy in March:

• Piedmont Park – Great for walking, jogging, and picnics on milder days
• Atlanta BeltLine Eastside and Westside Trails – Popular for biking and walking, especially on sunny weekends
• Freedom Park, Grant Park, and Historic Fourth Ward Park – Good for relaxed strolls as trees and flowers begin to bloom
• Atlanta Botanical Garden – Early spring blooms start showing, making March a popular time for visits

Because March can be wet, some unpaved paths may be muddy. Waterproof or easy‑to‑clean shoes are useful if you plan to explore nature areas.

Sports and Festivals

Depending on the year, March can feature:

• Spring training–style events or early baseball activities nearby
• Atlanta United home matches at Mercedes‑Benz Stadium starting up their season
• Various 5K and 10K races, community events, and neighborhood festivals

Stadium events and races generally go on in light rain but may be delayed for severe weather, so checking conditions before you leave is wise.

March Weather and Atlanta Pollen Season 🌸

For many people in Atlanta, March means pollen.

When Pollen Begins to Spike

• Tree pollen—especially from oak, pine, and other local species—often ramps up in March.
• Some years, the bright yellow‑green pollen dust on cars, sidewalks, and outdoor furniture becomes noticeable before the month ends.

Even if temperatures are mild, the air can feel less pleasant for people who are sensitive to pollen.

Practical Tips for Pollen Season

• Keep car windows closed on high‑pollen days while driving around the city.
• Consider changing clothes or rinsing off after long periods outdoors, particularly if you’ve been in parks or wooded areas.
• If you have allergy concerns, some residents check daily pollen counts shared by local media and weather services.

How March Weather Affects Driving and Commuting

Road Conditions

Snow and ice are rare in March, but other weather‑related issues can still affect Atlanta traffic:

• Heavy rain can create brief ponding on roads and highways.
• Thunderstorms may reduce visibility and slow traffic on I‑75, I‑85, I‑20, and the Downtown Connector.
• Tree debris and slick patches can appear after strong winds.

March is a good time to check your wipers and tire tread, especially if you rely on your car to navigate the city and suburbs.

Using MARTA and Other Transit

MARTA rail and bus service generally operates regardless of rain, but:

• Sudden thunderstorms can make platforms and bus stops windy and wet.
• A compact umbrella or rain jacket is useful if you transfer between trains and buses or walk a few blocks to your destination.

You can monitor local conditions and travel advisories through:

• Georgia Department of Transportation (GDOT)

Health and Comfort Considerations (Non‑Medical)

Without offering medical advice, many Atlantans keep a few comfort basics in mind for March:

• Dress in layers to avoid getting chilled in the morning and overheated by mid‑day.
• Stay dry if you’re out in steady rain; wet clothes in breezy 50s–60s°F temperatures can feel colder than the thermometer suggests.
• If you’re sensitive to barometric changes, March’s shifting weather patterns can be noticeable as fronts move in and out.
