Atlanta Weather in October: What to Expect and How to Prepare

October in Atlanta, Georgia is often one of the most comfortable and enjoyable times of year. The intense summer heat finally backs off, humidity drops, and fall colors start showing up in parks and neighborhoods across the city.

If you’re planning to live in, visit, or explore Atlanta in October, here’s exactly what you need to know about the weather and how to plan around it.

Typical Atlanta Weather in October

Atlanta’s October weather is best described as mild, pleasant, and increasingly fall-like.

Temperature overview

You can generally expect:

• Early October: Warm days, mild nights
• Mid-October: Noticeably cooler mornings and evenings
• Late October: More “true fall” days, with some chilly starts

Typical daily temperatures in Atlanta in October

Nights can feel quite cool, especially if you’re out late at outdoor events, in places like Piedmont Park, The Battery Atlanta, or at an evening game.

Humidity, Rain, and Storms

Humidity levels

Compared with summer, October humidity in Atlanta is usually much lower. You’ll notice:

• Far fewer sticky, muggy days
• Comfortable afternoons, especially in the shade
• Cooler, drier air in the mornings and evenings

This makes October a popular month for outdoor events, patios, hiking, festivals, and sports.

Rain patterns

October is not usually a washout month, but rain still happens.

You may see:

• Light to moderate showers a few days during the month
• An occasional passing cold front that brings clouds, gusty winds, and a day of rain
• At times, heavier rain if tropical systems in the Atlantic or Gulf track inland

Thunderstorms are less frequent than in summer, but they’re still possible, especially early in the month.

Daylight and Sunrise/Sunset Times

October brings shorter days as Atlanta moves deeper into fall.

• Early October:
  • Sunrise: roughly around 7:30 a.m. (shifts slightly during the month)
  • Sunset: roughly around 7:15–7:20 p.m.
• Late October:
  • Sunrise: closer to 7:50 a.m.
  • Sunset: around 6:40–6:50 p.m.

Evenings get dark earlier, which matters if you’re:

• Commuting from Downtown, Midtown, or Buckhead
• Going for after-work walks on the BeltLine
• Planning outdoor events or kids’ sports practices

Daylight Saving Time doesn’t end until early November, so the clock hasn’t changed yet, but you’ll feel the days getting noticeably shorter.

What to Wear in Atlanta in October

Packing or dressing for Atlanta weather in October means being ready for layers.

Everyday clothing tips

For most days, consider:

• Tops: T-shirts, light long-sleeve shirts, casual blouses
• Layers: Light sweater, cardigan, or thin jacket you can take on and off
• Bottoms: Jeans, chinos, or lightweight pants; shorts are still comfortable on warmer days
• Shoes: Sneakers, flats, or casual boots

You might leave home in a light jacket in the morning and be comfortable in short sleeves by afternoon.

For evenings and outdoor events

If you’re going to:

• A game at Mercedes-Benz Stadium or Truist Park
• An outdoor concert at Cadence Bank Amphitheatre at Chastain Park
• A fall festival or pumpkin patch in the metro area

Bring:

• A light to medium-weight jacket or fleece
• Possibly a scarf or hat for late October nights, especially if you get cold easily

For visitors staying in hotels

Hotel interiors and indoor spaces across Atlanta can be well air-conditioned, even in October. If you run cold indoors, you may want:

• A light sweater or long-sleeve layer for restaurants, shops, and offices
• Comfortable closed-toe shoes if you plan to walk the Atlanta BeltLine or explore Downtown and Midtown

Outdoor Activities and Events in October Weather

October is one of the best months for being outside in Atlanta. The weather typically supports:

• Festivals and fairs around the city and in nearby suburbs
• Hiking and nature walks at places like Stone Mountain Park, Sweetwater Creek State Park, or along the Chattahoochee River
• Patio dining in neighborhoods like Inman Park, Virginia-Highland, West Midtown, and Old Fourth Ward
• College and pro football tailgates and games

Because temperatures are milder and humidity is lower, you can usually spend hours outside comfortably, especially with:

• Sunscreen during midday
• A light jacket or extra layer in your bag for later

Air Quality, Allergies, and Comfort

Air quality

By October, Atlanta’s summer ozone and smog concerns usually ease, especially on cooler, breezy days. However:

• On calm, warmer days, haze is still possible
• Traffic-heavy corridors like the Downtown Connector (I-75/I-85) can feel stuffy during rush hour

Anyone sensitive to air quality may want to check daily forecasts from local outlets or the Georgia Environmental Protection Division.

Fall allergies

Many Atlanta residents notice fall allergies acting up in October due to:

• Ragweed
• Mold (especially after rain or in damp, leafy areas)
• Tree and grass pollen in some spots

People with seasonal allergies often keep tissues, over-the-counter remedies, and sunglasses handy to reduce irritation. For personal medical decisions or treatment, contacting a local clinic or provider is recommended.

How Atlanta October Weather Affects Daily Life

Commuting and traffic

Weather in October is usually not a major disruption for driving around the Atlanta metro, but you may see:

• Foggy mornings, especially in low-lying areas or near the Chattahoochee River
• Wet roads on days when a cold front moves through
• Occasional fallen leaves making some neighborhood streets slick when damp

Most major commuting routes—like I-285, GA-400, I-20, and I-85—operate normally, with standard rush-hour delays rather than weather-related issues.

Heating and cooling at home

In homes and apartments across Atlanta, October is often a transition month:

• Many people turn off central air for much of the month
• You may need light heat on a few especially cool mornings or nights, especially in late October
• Open-window days are common, particularly in shaded neighborhoods and higher-elevation spots

If you’re moving to Atlanta or staying long-term, October is a good time to:

• Schedule HVAC checks before winter
• Replace filters and test your heating system while the weather is still mild

Planning Travel to Atlanta in October

What visitors should pack

If you’re traveling to Atlanta in October, consider packing:

• Short-sleeve shirts and a couple of lightweight long-sleeves
• One or two sweaters or cardigans
• A light or medium jacket for cooler evenings
• Comfortable walking shoes for city exploration and parks
• Umbrella or compact rain jacket, just in case of showers
• Sunglasses and a hat for brighter afternoons

You’ll likely use all your layers at some point during the month because of the daily temperature swings.

At the airport and around town

Hartsfield–Jackson Atlanta International Airport (ATL) can feel warm and busy inside, but once outside, the October air is usually comfortable.

When you arrive:

• Check the daily high and low; dressing in layers helps when moving between indoor spaces, MARTA, rideshares, and walking around Downtown or Midtown.
• If you’re heading directly to a game, festival, or outdoor event, keep a light jacket in your bag even if it feels warm on arrival.

• Local TV stations based in Atlanta for detailed daily forecasts
