The National Weather Service office in Peachtree City is keeping a heat advisory in effect across metro Atlanta through the weekend as dangerously high temperatures and humidity combine to push the heat index well above 100°F.
Saturday’s high is forecast to reach approximately 92°F, with the heat index — what it actually feels like when humidity is factored in — climbing to 100°F or higher across much of the metro area. Sunday looks worse: highs near 95°F and a heat index that could reach the mid-100s.
The message from forecasters is simple: limit time outdoors, drink water, and check on people who are vulnerable to heat.
Why this weekend is especially concerning
Metro Atlanta gets hot every summer. But this weekend carries an extra layer of risk because of the World Cup.
Tens of thousands of visitors — many from cooler climates and unfamiliar with Georgia’s summer heat and humidity — are spending extended time outdoors at fan zones, Showcase Atlanta activations, and the FIFA Fan Festival at Centennial Olympic Park. Even on today’s off-day between matches, the fan festival and other outdoor events are drawing large crowds.
Heat-related illness does not require extreme temperatures. A heat index above 100°F, combined with prolonged sun exposure and physical activity, can lead to heat exhaustion and heat stroke — both medical emergencies.
Sunday could be the worst day
The NWS forecast for Sunday, June 29 calls for:
- High temperature: Near 95°F
- Heat index: Mid-100s, potentially approaching 105°F in some areas
- Humidity: Dew points in the low to mid-70s
- Thunderstorm risk: Scattered storms possible in north and east Georgia during the afternoon and evening
The scattered thunderstorm threat could provide temporary relief in areas where storms develop, but forecasters caution that storms will be isolated and many parts of the metro will not see rain. In areas that do get storms, the lightning risk adds another safety concern for people spending time outdoors.
Heat safety reminders
The NWS and local emergency management agencies are urging residents and visitors to take precautions:
- Hydrate frequently. Do not wait until you feel thirsty. Drink water consistently throughout the day.
- Seek shade. If you are attending an outdoor event, take breaks in shaded or air-conditioned areas.
- Avoid peak sun. The hottest part of the day is typically between noon and 5 p.m.
- Check on vulnerable people. The elderly, young children, and those with chronic health conditions are at highest risk.
- Never leave children or pets in a parked vehicle. Interior temperatures can exceed 130°F in minutes.
- Know the signs of heat illness. Heavy sweating followed by a sudden stop in sweating, dizziness, nausea, rapid heartbeat, and confusion are warning signs. Call 911 immediately for suspected heat stroke.
Cooling resources
The City of Atlanta and Fulton County have opened cooling centers at libraries and recreation centers across the metro. The city’s 311 line can direct residents to the nearest cooling center.
Many World Cup fan-zone organizers have added misting stations and water distribution points at outdoor activation sites, though officials stress that individual preparation is the most reliable protection.
Looking ahead
Temperatures are expected to moderate slightly in the first days of July, but forecasters say the broader pattern of above-average heat is likely to persist through the first half of the month — a stretch that coincides with the most high-profile World Cup matches remaining on Atlanta’s schedule.
