Quick Snapshot of Atlanta Weather in May

Here’s a simple overview of typical May conditions in Atlanta:

These are general patterns, not guarantees, but they reflect what most Atlantans experience in May.

Temperatures in Atlanta in May

Daytime temperatures

May in Atlanta usually feels warm but not fully summer-hot yet.

• Many days reach the mid-70s to low 80s°F.
• Early May can feel like mild spring; late May can feel like early summer.
• On sunnier, still days, it can feel hotter than the thermometer suggests, especially on pavement and in direct sun.

You’ll likely be comfortable in short sleeves during the day, especially walking around areas like Piedmont Park, the BeltLine, or Downtown/Midtown.

Nighttime temperatures

Evenings and early mornings in May are often pleasant and cooler:

• Temperatures frequently drop into the 50s and low 60s°F.
• Rooftop patios and outdoor dining in neighborhoods like Old Fourth Ward, Inman Park, and West Midtown are usually comfortable with a light layer.

If you’re planning to be out late—say at a game near Truist Park or an outdoor show at Chastain Park Amphitheatre—bringing a light jacket or sweater is a good idea, especially in early May.

Rain, Thunderstorms, and Severe Weather

Typical rain patterns in May

Atlanta’s May weather often includes:

• Scattered showers that can pass quickly
• Afternoon or evening thunderstorms, especially on warm, humid days
• Periods of several dry, sunny days in between rain events

Rain is not usually an all-day event every time; it’s common for storms to roll through and move out, leaving clearer skies afterward.

Thunderstorms and severe weather risks

May is part of Atlanta’s active thunderstorm season. You may encounter:

• Thunder and lightning
• Heavy downpours that can cause brief, localized street flooding
• Gusty winds
• Occasionally severe storms, which can bring strong wind, hail, and more intense lightning

If you’re in Atlanta during May, it’s smart to:

• Keep an eye on local forecasts from stations based in Atlanta or through weather apps.
• Pay attention to warnings or alerts issued through Fulton County or the City of Atlanta emergency channels.
• Have a plan to move indoors quickly if skies darken and thunder starts.

For up-to-date alerts, residents and visitors can follow local information from:

• City of Atlanta – Office of Emergency Preparedness
  • 55 Trinity Ave SW, Atlanta, GA 30303
  • Main City information line: (404) 330-6000

Humidity and “Feel” of the Air

Atlanta is known for its humidity, and in May you’ll start to feel it more consistently.

• Early May: Humidity is often moderate, and the air can feel fresh and comfortable, especially in the mornings.
• Late May: Conditions can feel more muggy, especially during the afternoon, giving a preview of Atlanta’s summer.

On humid days:

• Shade in places like Grant Park, Piedmont Park, or wooded trails around the Chattahoochee River can feel noticeably cooler.
• You may sweat more quickly when walking in direct sun, especially on concrete-heavy areas like Downtown or Buckhead.

Air Quality and Allergies

Pollen and seasonal allergies

Spring pollen season often continues into May in Atlanta, though it tends to peak earlier (March–April). In May:

• Tree pollen may start to ease.
• Grass pollen can still be noticeable.
• Some days with wind and dry weather may feel more irritating for sensitive individuals.

If you’re sensitive to pollen:

• Keep car and home windows closed on high-pollen days.
• Use recirculated air in your car when driving around Atlanta.
• Plan heavy outdoor activity (like running on the Atlanta BeltLine Eastside Trail) for times when pollen counts are typically lower, such as after rain.

For local air and pollen updates, Atlantans often check:

• Georgia Environmental Protection Division (EPD)
  • 2 Martin Luther King Jr. Dr SE, Suite 1456, Atlanta, GA 30334
  • Main office: (404) 657-5947

Air quality considerations

On most May days, air quality in Atlanta is generally acceptable for outdoor activities. However:

• Warmer, stagnant days can occasionally lead to poorer air conditions.
• Traffic-heavy corridors like Downtown Connector (I‑75/85) and I‑285 can feel more polluted during rush hours.

If you’re sensitive to air quality, consider:

• Exercising earlier in the morning.
• Using parks and trails set back from major roads, such as parts of the Chattahoochee River National Recreation Area or deeper sections of Freedom Park.

What to Wear in Atlanta in May

Clothing basics

For most people, a spring-to-summer wardrobe works best:

• Tops: T‑shirts, light blouses, short-sleeve shirts, breathable fabrics
• Bottoms: Jeans, light pants, shorts, skirts, or dresses
• Layers: A light jacket, cardigan, or hoodie for cooler mornings and evenings
• Footwear: Comfortable walking shoes, sneakers, or sandals for outdoor exploring

If you’re commuting or sightseeing around Midtown, Downtown, or Buckhead, plan for walking in mixed sun and shade. Breathable materials will keep you more comfortable.

Rain gear and accessories

Because of frequent showers and storms:

• Carry a compact umbrella or a light rain jacket if you’ll be out all day.
• Consider water-resistant shoes if you expect heavy rain.
• A hat and sunglasses are helpful for bright, sunny stretches, especially in open areas like Centennial Olympic Park.

Outdoor Activities and Events in May

May is a prime month for outdoor life in Atlanta, as long as you’re mindful of heat and storms.

Parks, trails, and green spaces

Popular outdoor spots are especially enjoyable in May:

• Piedmont Park – Great for picnics, walking, or festivals.
• Atlanta BeltLine – Ideal for biking, walking, and checking out restaurants and public art.
• Grant Park, Freedom Park, and neighborhood greenspaces – Often lively on weekends.

Tips for enjoying them in May:

• Outdoor attractions like the Atlanta Botanical Garden or Zoo Atlanta.

When attending events:

Getting around in changing weather

Rain showers and storms can affect both driving and public transit:

• If you’re using MARTA trains or buses, it’s wise to allow extra time during storms and to bring an umbrella for walking between stations and destinations.

Safety and Preparedness for May Weather

Storm and lightning safety

If a thunderstorm develops:

• Move indoors—into a building or fully enclosed vehicle—if you hear thunder.
• Avoid open fields, hilltops, and metal bleachers in parks like Piedmont Park or Grant Park.
• Wait until 30 minutes after the last thunder before resuming outdoor activities.

Many city facilities and large venues in Atlanta have designated shelter areas or indoor spaces, so locate them early if you’re attending outdoor events.

Flooding and heavy rain

Most May storms in Atlanta pass without major problems, but very heavy rain can cause:

• Brief street flooding, especially in low-lying areas and underpasses.
• Slower commutes and delays around major intersections and highways.

If you’re driving:

• Do not drive through water that looks deeper than a few inches; depth can be misleading.
• Use alternate routes if you see significant standing water.

How May Compares to Other Months in Atlanta

Understanding May in context can help you plan:
