Planning time in Atlanta in October? You’ve picked one of the most comfortable months of the year. October weather in Atlanta is known for mild days, cooler nights, and much lower humidity than summer—ideal for festivals, outdoor dining, and exploring city neighborhoods.

Below is a clear, Atlanta-focused guide to what October is really like, plus what to pack, what to watch for, and how it affects daily life and travel.

Overall: Atlanta’s October Weather at a Glance

By October, Atlanta is easing out of the long, hot, humid summer and sliding into a much more comfortable fall.

Typical October patterns in Atlanta:

• Mild afternoons that often feel warm in the sun
• Cool, sometimes chilly mornings and evenings
• Lower humidity compared with summer
• Generally pleasant, with occasional rain systems and a few hot or cold swings

Here’s a simple overview of what you can usually expect:

Conditions can vary year to year, but this is the general feel Atlanta residents and visitors experience most Octobers.

Temperatures: How Warm or Cool Is October in Atlanta?

Daytime Temperatures

October afternoons in Atlanta are often described as “just right”:

• Early October can still feel a bit like late summer, with some days reaching the low 80s°F.
• Mid- to late October typically sits in the upper 60s to mid-70s°F during the day.
• In the sun, especially walking around Midtown, the BeltLine, or downtown, it can feel warmer than the numbers suggest.

If you’re planning outdoor activities—like visiting Piedmont Park, the Atlanta Botanical Garden, or zoo days—October is usually a comfortable time to stay outside for hours.

Morning and Evening Temperatures

Mornings and evenings are where you’ll notice the shift toward fall:

• Early morning lows often land in the 50s°F.
• Late October can bring a few mornings in the upper 40s°F, especially in more shaded or higher-elevation spots around the metro area.
• Even if the afternoon warms up, evenings on patios or at outdoor events can feel crisp.

Locals often keep a light jacket or sweater handy for early commutes, evening walks on the BeltLine, or fall festivals.

Rain, Storms, and Tropical Influences

How Rainy Is October in Atlanta?

October is not usually one of Atlanta’s soggiest months, but you should still expect:

• A handful of rainy days scattered through the month
• Most rain falling with passing fronts, not all-day washouts
• Some stretches of several dry, sunny days in a row

Rain can come as:

• Light showers
• Brief downpours with a cold front
• Overcast, drizzly days (less common but possible)

Keeping a small umbrella or light rain jacket in the car or day bag is practical if you’ll be out and about.

Storms and Severe Weather

Atlanta’s peak severe-weather seasons are usually spring and late fall, but October can still bring:

• Thunderstorms with a strong cold front
• Gusty winds and quick-changing skies
• Occasionally, strong storms that might bring down small limbs or cause localized power outages

For real-time alerts while you’re in the city, many locals rely on:

• Wireless emergency alerts on mobile phones
• Local TV and radio stations
• Weather apps with push notifications

The National Weather Service office that serves metro Atlanta is based in Peachtree City:

• National Weather Service – Peachtree City Office
  4 Falcon Drive
  Peachtree City, GA 30269

They provide official watches, warnings, and forecasts for Atlanta and surrounding counties.

Tropical Systems

Atlanta is far inland, but remnants of tropical storms or hurricanes in the Gulf or Atlantic can still affect October weather:

• Periods of steady, sometimes heavy rain
• Cloudy, breezy days
• Cooler temperatures under cloud cover

Major impacts like coastal storm surge don’t reach Atlanta, but travel plans (especially flights at Hartsfield-Jackson Atlanta International Airport) and outdoor events can be affected by these large storm systems.

Humidity and Air Quality in October

One of the biggest differences between October and Atlanta’s summer is how the air feels.

Humidity

By October:

• Humidity is usually moderate to low compared with July and August.
• Afternoons feel far less sticky, even on warmer days.
• You’re more likely to want a light layer in the morning than to feel weighed down by muggy air.

This is why October is a favorite month for outdoor dining, festivals, and hiking in the metro area and nearby North Georgia mountains.

Air Quality

Atlanta’s air quality tends to be better in fall than in peak summer:

• Less heat and high ozone conditions
• Less wildfire smoke influence than some summer periods (though smoke can occasionally drift in any time of year)

If you’re concerned about air quality, you can check local air quality indexes through:

• Weather apps
• Local news broadcasts
• National and state environmental resources

On most October days, many people find outdoor exercise—like running on the BeltLine, biking in Piedmont Park, or walking around Grant Park—fairly comfortable.

Sunrise, Sunset, and Daylight in October

October marks a noticeable shift in daylight in Atlanta:

• Early October:
  • Sunrises are still relatively early.
  • Evenings stay light enough for after-work outdoor time.
• Late October:
  • Mornings get noticeably darker when kids head to school.
  • Sunsets move earlier into the early evening.

Daylight Saving Time (the clock change) typically happens in early November, but by the last week of October you’ll already feel evenings creeping closer, which can affect:

• Outdoor sports practices and games
• After-work exercise routines
• Timing for outdoor events, patios, and attractions

If you’re planning photo sessions, scenic walks, or rooftop dinners, check the specific sunrise and sunset times for your dates, especially late in the month.

What to Wear in Atlanta in October

Packing or dressing for Atlanta in October is all about layers.

Clothing Tips for Locals and Visitors

Here’s a practical guide:

• Tops:
  • Short-sleeve shirts or light blouses for midday
  • A light sweater, cardigan, or hoodie to throw on mornings and evenings
• Bottoms:
  • Jeans, chinos, or casual pants
  • Some days are still warm enough for shorts or skirts, especially in early October
• Outerwear:
  • A light jacket (denim, light fleece, or a thin windbreaker)
  • A slightly warmer layer is helpful if you’ll be out late in late October
• Shoes:
  • Comfortable walking shoes or sneakers for city exploring
  • Closed-toe shoes are more comfortable on cooler mornings
• Extras:
  • Compact umbrella or lightweight rain jacket
  • Sunglasses and sunscreen for sunny afternoons
  • A light scarf can be helpful at outdoor events at night

Think in terms of “cool at 7 a.m., comfortable at 2 p.m., cool again at 9 p.m.” and you’ll pack correctly.

How October Weather Affects Daily Life in Atlanta

Events, Festivals, and Outdoor Activities

October is prime event season in Atlanta because of the comfortable weather. Popular fall happenings often include:

• Outdoor festivals and neighborhood events
• College and pro football games
• Pumpkin patches and corn mazes in the metro and nearby rural areas
• Outdoor concerts, markets, and art shows

Because the weather is usually pleasant:

• Crowds can be larger at parks and festivals on sunny weekends.
• Parking around busy areas like Piedmont Park, Midtown, Grant Park, and stadiums can be tight.

Checking the forecast and dressing in layers will keep you comfortable from morning to night.

Commuting and Traffic

Weather-related disruptions are usually minimal in October compared with winter or spring storms:

• Most days: normal Atlanta traffic, not weather-driven delays.
• On rainy mornings or evenings, expect slower commutes on interstates like I‑75, I‑85, I‑20, and the Perimeter (I‑285).
• Thunderstorms with heavy rain can cause ponding on roads and reduced visibility.

If you use MARTA (buses and rail) or other transit, October weather rarely causes major weather shutdowns, but heavy rain can still slow travel times.

Travel Planning: Flights, Driving, and Outdoor Plans

Flying Into or Out of Atlanta in October

At Hartsfield-Jackson Atlanta International Airport (ATL), October weather is often cooperative:

• Fewer heat-related delays than mid-summer
• Less risk of snow or ice than in winter
• Some delays still possible with strong thunderstorms or remnants of tropical systems

If you’re catching early morning or late-night flights, have a light jacket; the walk to parking decks, rideshares, or MARTA can feel cool.

Road Trips and Driving

October is a good month for driving to and around Atlanta:

• Comfortable conditions for long drives on I‑75, I‑85, or I‑20
• Occasional wet roads with fall cold fronts
• More leaf litter on neighborhood streets and some roads by late October, which can be slick when wet

If you’re heading to North Georgia for fall color (mountain towns, hiking spots, or state parks), be prepared for cooler temperatures than in the city, especially in the mornings and evenings.

Health and Comfort Considerations

While October weather in Atlanta is generally easy on most people, a few factors are worth noting:

• Allergies:
  • Fall pollen (especially ragweed and mold) can still be an issue for some residents and visitors.
  • Dry, breezy days can spread allergens more widely.
• Sun exposure:
  • The sun is less intense than in summer, but you can still get sunburned during long outdoor days.
  • Sunscreen, hats, and sunglasses are still helpful at festivals, parks, and sporting events.
• Temperature swings:
  • Rapid changes—like a cool, damp morning warming quickly to a sunny afternoon—can catch people off guard if they dress only for one part of the day.
  • Keeping a layer in your car or bag is an easy solution.

For official weather-related health advisories in the Atlanta area, information often comes through:

• The National Weather Service (Peachtree City office)
• State and local health and emergency management agencies
• Local news outlets
