• Snow is rare, and when it happens, even small amounts can impact roads and schools.
• Rainy days are common; cold, clear days pop up in between.

What locals and visitors should know:

Practical tips:

• If a winter weather advisory is issued, give yourself extra time on MARTA, local roads, and interstates.
• Check local weather before heading to Hartsfield–Jackson Atlanta International Airport, where delays can ripple quickly.

Spring in Atlanta (March–May)

What it’s like:

• Thunderstorms become more frequent, especially in late spring.

What to expect outdoors:

• Mornings can be cool; afternoons often feel warm.
• Short, intense thunderstorms may roll through, sometimes with lightning and gusty winds.

Practical tips:

What it’s like:

• Summers are hot and humid, with daytime highs often in the upper 80s to 90s°F.
• Late-afternoon pop-up thunderstorms are common, especially when heat and humidity build.
• Heat index values can make it feel hotter than the actual air temperature.

Key weather factors:

• Heavy downpours: Sudden storms can cause localized flooding on low-lying roads and underpasses.

Practical tips:

• Stay hydrated and take breaks in shade or air-conditioned spaces, such as downtown office towers, malls, and MARTA stations.
• For outdoor work or exercise on trails like the Silver Comet Trail or the Atlanta BeltLine, aim for early mornings or later evenings.

Tornadoes are not an everyday occurrence in the city, but they are taken seriously when watches or warnings are issued.

Practical safety basics:

• If you’re staying in a hotel downtown, ask staff or review posted safety information to know where to go in severe weather.

Heat, Humidity, and Air Quality in Atlanta

Heat and Humidity

In summer, much of Atlanta’s discomfort comes from high humidity, especially:

• Around midday and afternoon
• In areas with limited shade or tree cover
• On paved surfaces like big parking lots or busy roadways

How locals cope:

• Using public parks, shaded green spaces, and indoor venues to escape peak heat
• Timing outdoor activities, errands, and exercise for earlier or later in the day

Air Quality and Pollen

Atlanta can experience reduced air quality at times due to:

• Ozone on hot, stagnant days
• Vehicle traffic in dense corridors
• Pollen surges in spring

If you are sensitive to these conditions:

• Monitor local forecasts that mention “air quality alerts” or “code orange/red” days.
• Consider scheduling outdoor activities for times when air quality is reported as moderate or better.

Flooding and Heavy Rain in the Atlanta Area

Heavy rains, especially from slow-moving storms or tropical moisture, can lead to:

• Street flooding in low-lying neighborhoods
• Water collecting under railroad underpasses, highway underpasses, and small creeks
• Brief but intense drainage backups in parts of the city

What to watch for:

• Avoid driving through standing water, particularly at underpasses and poorly drained intersections.
• Give yourself extra travel time when rain is in the forecast, especially during rush hours.

Tropical Systems and Remnants

Atlanta is inland, but it can still be affected by:

• Remnants of tropical storms or hurricanes
• Prolonged periods of rain and gusty winds
• Isolated power outages from downed limbs and lines

These systems usually bring lots of rain rather than hurricane-force winds, but they can still disrupt travel and outdoor plans.
