Quick Overview: Atlanta Weather in March

Here’s a simple snapshot of what Atlanta March weather is typically like:

These are general patterns, not guarantees. March can serve up a few almost-winter days and a few almost-summer days in the same week.

Temperature: From Chilly Starts to Mild Afternoons

Typical Daytime Highs

During March in Atlanta:

• Afternoons usually climb into the 60s°F, with warm stretches that can reach the 70s°F.
• On cooler days, highs may stay in the 50s°F, especially early in the month.

This makes March one of the most pleasant times to be outdoors in the city, from walking the BeltLine to visiting Piedmont Park or Grant Park.

Morning and Nighttime Lows

Overnight and early morning temperatures tend to be:

• In the 40s°F, sometimes dipping into the upper 30s°F early in the month.
• Occasional light frost is still possible, especially in the first half of March, though it’s not an everyday occurrence.

If you’re heading out early—whether to MARTA stations, the airport, or morning runs on the Silver Comet Trail—you’ll want a jacket.

Clothing Tips for March Temperatures

Because of the swings between morning and afternoon:

• Layering is key:
  • Light or medium-weight jacket in the morning
  • Long sleeves or light sweater as a base layer
  • Option to switch to a T-shirt or lighter top by afternoon
• Keep a compact rain jacket or windbreaker in your bag, especially if you’ll be out all day.

Rain and Storms: March Can Be Wet and Stormy

How Rainy Is March in Atlanta?

March typically brings:

• Regular rain chances, from light showers to steady rain.
• Several rainy days spread through the month, not necessarily all-day washouts.
• Periods of overcast, gray skies between sunny stretches.

Atlanta’s March weather is influenced by changing seasons, so cold fronts and warm, moist Gulf air can clash, bringing more active weather patterns.

Thunderstorms and Severe Weather Potential

March is part of the early severe-weather season for north Georgia. It is not unusual to see:

• Thunderstorms, some with:
  • Heavy rain
  • Lightning
  • Gusty winds
• Occasional strong to severe storms, which can include:
  • Damaging straight-line winds
  • Small hail
  • Isolated tornadoes in the region

Severe weather does not happen every day, but it’s something Atlanta residents stay aware of in March.

⚠️ Smart habits in March:

• Keep a reliable weather app on your phone with alerts turned on.
• If you hear about a severe thunderstorm or tornado watch/warning, move indoors and stay away from windows until it passes.
• If you’re visiting and staying in a hotel, know where the interior hallway or designated shelter area is.

For local emergency information and preparedness guidance, residents can refer to Fulton County Emergency Management Agency (public contact information is typically listed through county offices and public safety channels).

Humidity and Comfort Level

Atlanta’s humidity in March is:

• Noticeable on milder, rainy days but
• Less intense than the thick humidity of late spring and summer.

On many days, the weather feels:

• Comfortably mild during the afternoon
• Slightly cool and damp after rain or in the evenings

It’s a good time for outdoor activities like:

• Walking around Midtown or Downtown
• Visiting the Atlanta Botanical Garden
• Hiking at Stone Mountain Park or Chattahoochee River National Recreation Area

Daylight, Time Change, and Daily Rhythm

Daylight Saving Time in March

In March, Atlanta:

• “Springs forward” to Daylight Saving Time (usually the second Sunday in March).
• This shifts clocks one hour ahead, giving you:
  • More evening daylight
  • Darker mornings for a short time

This change can be particularly helpful if you like:

• Evening runs on the BeltLine
• After-work visits to parks, patios, or outdoor events

Sunrise and Sunset

By late March in Atlanta, you can generally expect:

• Earlier sunrises than winter, though not extremely early
• Later sunsets, often after 7:00 p.m., depending on the date

This longer daylight window pairs nicely with the milder temperatures for after-work outings and weekend plans.

Pollen and Early Spring Allergies

March is often the start of pollen season in Atlanta, especially:

• Tree pollen, which can spike noticeably during warm, dry stretches.
• The beginning of the city’s familiar yellow pollen dust on cars, porches, and sidewalks, especially late March into early April.

If you’re sensitive to pollen:

• Check daily pollen counts through local news or weather services.
• Keep windows closed on high-pollen days, especially while driving or sleeping.
• Consider rinsing off or changing clothes after extended time outdoors.

Public health questions related to allergies, asthma, or respiratory conditions can often be discussed with local health providers or, for general information, through organizations such as the Fulton County Board of Health.

Best Outdoor Activities for March Weather in Atlanta

Because March is often pleasantly mild, it’s a strong month for exploring the city.

Attractions and Events
