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

October is one of the most comfortable and popular months of the year in Atlanta, Georgia. The intense summer heat starts to fade, humidity drops, and the city’s parks, neighborhoods, and outdoor venues become especially inviting.

If you live in Atlanta or are planning a fall trip, understanding Atlanta weather in October can help you pack smart, plan outdoor plans, and know what to expect day to day.

Typical Temperatures in Atlanta in October

October in Atlanta is generally mild and pleasant, with a noticeable shift from warm early in the month to cool by the end.

Typical temperature range:

Key points:

• Afternoons are usually warm enough for short sleeves.
• Mornings and nights can feel cool, especially later in the month.
• Indoor spaces (offices, restaurants, hotels) may still run air conditioning some days, but you’ll also see more people in light jackets outside.

Humidity and “Feel” of the Air

If you’re used to Atlanta’s sticky summers, October will feel like a relief.

• Humidity drops compared to July and August.
• The air often feels crisper and drier, especially in the mornings.
• On some days after a rain, it can still feel a bit muggy, but it’s usually manageable.

For many Atlanta residents, October is prime “porch weather” and perfect for patios at restaurants around Midtown, Inman Park, and the BeltLine.

Rain, Storms, and Tropical Influences

October is not the rainiest month in Atlanta, but showers are still possible.

Rain Patterns

• Expect scattered light to moderate showers a few days during the month.
• All-day washouts are less common but can happen.
• Many days are clear or partly cloudy, making October a good month for outdoor plans.

Tropical Systems

October falls near the tail end of Atlantic hurricane season. While hurricanes do not directly hit Atlanta, remnants of tropical systems can:

• Bring periods of heavy rain
• Create gusty winds
• Lead to downed branches and localized flooding in low-lying areas

When a tropical system is forecast, people in Atlanta often:

• Watch updates from local TV stations and the National Weather Service (NWS) Atlanta office
• Allow extra travel time, especially on I‑285, I‑75, I‑85, and GA‑400

Daylight and Sunset Times in October

Days get noticeably shorter through the month.

Approximate pattern:

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

There is no time change during October itself (Daylight Saving Time ends in early November), but you’ll definitely notice darker evenings if you’re out on the Atlanta BeltLine, in Piedmont Park, or commuting home.

What to Wear in Atlanta in October

October is classic “layering season” in Atlanta. Your clothing needs can shift over the course of a single day.

Everyday Clothing Tips

For most people, this kind of wardrobe works best:

• Tops:
  • Short-sleeve shirts or light blouses for daytime
  • Light sweater, cardigan, or long-sleeve shirt for mornings/evenings
• Bottoms:
  • Jeans, chinos, or casual pants
  • On warmer days, shorts or skirts are still comfortable
• Outerwear:
  • Light jacket (denim, windbreaker, or thin puffer)
  • A slightly warmer layer if you run cold or will be out late at night
• Shoes:
  • Comfortable walking shoes or sneakers for exploring neighborhoods and trails
  • Closed-toe shoes are more comfortable on cooler or rainy days

Packing Tips for Visitors

If you’re visiting Atlanta in October:

• Pack for both warm and cool conditions—not heavy winter gear, but enough layers.
• Include:
  • 1–2 light jackets
  • A compact rain jacket or small umbrella
  • Comfortable shoes for walking in Downtown, Midtown, and along the BeltLine
• If you’re attending a game at Mercedes-Benz Stadium or Truist Park, remember indoor stadiums and crowds can feel warmer than the outside air.

Outdoor Activities and Seasonal Events in October

October weather in Atlanta is ideal for getting outside.

Popular Outdoor Spots

With comfortable temperatures and lower humidity, you can enjoy:

Fall Festivals and Events

Many Atlanta fall festivals and neighborhood events land in October because the weather is so cooperative. People often plan:

• College football tailgates and Falcons game days

For these, it’s wise to:

• Dress in layers 🌤️

Air Quality, Allergies, and Seasonal Changes

October can feel easier for many people than peak summer, but there are still a few things to keep in mind.

Air Quality in Atlanta in October

• Atlanta’s summer ozone issues usually ease up by October due to cooler temperatures.
• On days with stagnant air or lingering haze, sensitive groups may still notice some discomfort.
• When air quality is a concern, local officials may share information through the Georgia Environmental Protection Division (EPD) and City of Atlanta communication channels.

Fall Allergies

Even though the worst of spring pollen is over, some people notice fall allergies:

• Ragweed and other weeds can trigger symptoms.
• Cooler air sometimes encourages more open windows, which can let allergens inside.

If you’re sensitive, keeping an eye on local pollen counts and rinsing off after outdoor activities can be helpful.

How October Compares to Other Atlanta Seasons

Understanding October weather is easier when you see it next to other times of year:

• Compared to summer (June–August):
  • Much cooler and far less humid
  • Fewer late-day thunderstorms
  • More comfortable for walking in neighborhoods like Virginia-Highland or Old Fourth Ward
• Compared to winter (December–February):
  • Warmer and more stable weather
  • Very low chance of ice or snow
  • Less need for heavy coats, hats, and gloves
• Compared to spring (March–May):
  • Similar mild temperatures, but less pollen than peak spring
  • Often more predictable day-to-day than early spring

For many Atlanta residents, October and April compete as the most pleasant months of the year.
