Atlanta October Weather: What to Expect and How to Plan

October is one of the most comfortable months of the year in Atlanta, Georgia. The intense summer heat finally breaks, humidity drops, and fall colors start to show up across neighborhoods and parks. If you live in Atlanta or you’re visiting in October, this is a great time to be outside—if you know what to expect from the weather.

Typical Atlanta Weather in October

Atlanta’s October weather is best described as mild, pleasant, and changeable. You’ll often experience cool mornings, warm afternoons, and crisp evenings, with occasional rainy days.

Temperature overview

You can usually expect:

• Average highs: upper 60s to mid-70s °F
• Average lows: upper 40s to mid-50s °F
• Overall feel: light-jacket weather in the morning, T-shirt weather by mid-afternoon on many days

Cool fronts can bring a brief taste of chilly, almost winter-like mornings, especially late in the month, while a few lingering summer-like afternoons sometimes still show up in early October.

Humidity and comfort

Compared to Atlanta’s muggy summers, October feels much drier and more comfortable. You’re less likely to deal with heavy humidity, although:

• Early October can still have a slightly muggy afternoon or two.
• Later in the month, the air often turns crisper and drier, especially after a cold front moves through.

This makes October a popular time for outdoor festivals, football games, and hiking around the metro area.

Rain, Storms, and Tropical System Remnants

While October is not Atlanta’s rainiest month, you should still plan for occasional wet days.

Rain patterns

You may notice:

• Light to moderate showers spread across a few days each month
• Mostly dry stretches, especially when high pressure settles in
• A lower chance of daily afternoon thunderstorms compared to summer

Rain is often tied to passing cold fronts, which can also bring a noticeable drop in temperatures for a couple of days afterward.

Tropical influences

October is still within the Atlantic hurricane season. Atlanta is far inland, so direct hits are not a concern, but:

• Remnants of tropical storms or hurricanes can bring periods of steady rain and gusty winds.
• These events are usually well-forecast several days in advance, giving you time to adjust your plans.

When a tropical system’s remnants move through, you might see:

• Gray, overcast skies
• Cooler daytime highs than usual
• Slick roads and slower traffic on major routes like I-285, I-75, I-85, and I-20

Daylight and Sunrise/Sunset in October

By October, the long summer days are over, and Atlanta edges toward shorter daylight hours.

• Early October: Sunrise around 7:30 a.m., sunset close to 7:15–7:20 p.m.
• Late October: Sunrise closer to 7:50 a.m., sunset around 6:45 p.m.

Daylight saving time ends in early November, not October, so clocks stay the same all month. Still, you’ll notice:

• Dark mornings for early commuters and school drop-offs
• Earlier sunsets, affecting evening outdoor activities and rush hour visibility

This shift matters if you’re planning evening walks on the BeltLine, late rounds of golf, or outdoor dining around Midtown, Buckhead, or Inman Park.

How Atlanta’s October Weather Compares to Other Seasons

Understanding Atlanta’s October weather is easier when you compare it to the rest of the year:

• Compared to summer (June–August):

  • Much cooler and lower humidity
  • Far fewer afternoon thunderstorms
  • More comfortable for walking around Downtown, visiting attractions, or attending outdoor events

• Compared to winter (December–February):

  • Warmer and less harsh, especially in the mornings and evenings
  • No routine freezes, though the first light frost sometimes appears late in October in outlying suburbs
  • Rare to see any wintry weather

• Compared to spring (March–May):

  • More stable temperatures—spring can swing from chilly to hot quickly
  • Typically fewer strong thunderstorms than the late-spring peak
  • Less pollen than peak spring, though some people may still notice milder allergies

What to Wear in Atlanta in October

October is a layering month in Atlanta. Your clothing choices may need to adjust within the same day.

Everyday clothing tips

Consider:

• Light layers: T-shirts, long-sleeve shirts, and a light sweater or hoodie
• A medium-weight jacket for cool mornings and nights
• Comfortable jeans or chinos; shorts may still be comfortable on warmer afternoons, especially early in the month
• Closed-toe shoes or sneakers for walking, especially if you’ll be in parks or on trails

You’ll see a mix of outfits around Atlanta in October: some people in light jackets, others still in short sleeves on warmer days.

If you’re planning time at:

• Piedmont Park
• Atlanta BeltLine
• Chattahoochee River National Recreation Area
• Stone Mountain Park

You may want:

• A light jacket or fleece for early or late in the day

Outdoor Events and Activities in October Weather

October weather in Atlanta lines up well with many fall events and outdoor activities.

Festivals and sports

The city and metro area often host:

• Neighborhood fall festivals
• College and pro football games, with tailgating in cooler conditions
• Outdoor arts, music, and food events across Midtown, Downtown, and surrounding suburbs

The mild daytime temperatures make it easier to spend several hours outside without overheating, but it’s smart to:

• Bring a light jacket for evening events
• Pack a small umbrella if there’s a chance of showers
• Wear comfortable walking shoes, as many events involve a lot of standing and walking

Parks and trails

Cooler temperatures make October a great time to explore:

• Atlanta BeltLine Eastside and Westside Trails
• Piedmont Park, Grant Park, and Freedom Park
• Suburban green spaces in Sandy Springs, Roswell, Decatur, and beyond

You’ll likely find:

• Comfortable midday temperatures for jogging, biking, or walking dogs
• Early hints of fall foliage, especially late in the month
• Cooler breezes near shaded or higher-elevation areas

Fall Foliage and Seasonal Changes

While Atlanta doesn’t get fall color as early or intense as some mountain areas, October starts the transition.

• Early October: Mostly green trees, with a few early color changes
• Mid to late October: Increasing yellows and some reds, especially in parks and older neighborhoods
• Peak color in Atlanta: Often runs into late October or early November

Nearby higher-elevation areas, like North Georgia and the Chattahoochee National Forest, may see color earlier, making October a popular month for day trips from Atlanta.

Air Quality, Allergies, and Comfort

October often sees an improvement in air quality compared to hot, stagnant summer days. The cooler temperatures and reduced ozone patterns can make outdoor time more comfortable for many people.

However:

• Some people may still notice fall allergies, especially to weeds or leaf mold.
• If you’re sensitive, you may want to keep an eye on daily pollen and air quality updates before planning a long outdoor day.

Driving and Commuting in October Weather

For most of October, weather has less impact on commuting than in the stormier or colder months. Still, there are a few things to keep in mind:

• Morning fog can occasionally form, especially around rivers, low-lying areas, and outskirts of the metro.
• Wet leaves on roads after rain can make surfaces slick, particularly in tree-lined neighborhoods.
• Earlier sunsets mean more driving in the dark during evening rush hour on major interstates and surface streets.

Allowing extra time on days with rain or fog is helpful, especially on busy routes like:

• Downtown Connector (I-75/85)
• I-285 Perimeter
• GA-400 and other major corridors

Monitoring October Weather in Atlanta

Conditions can change quickly when a cold front or tropical system passes through, so staying informed is useful—especially for outdoor events, travel, or construction projects.

You can:

• Check local TV and radio weather forecasts from Atlanta-based stations
