The sequence of high heat and humidity will last the entire work week.
ATLANTA — The first significant heat wave of the summer is coming to northern Georgia starting Sunday. Highs will climb to the low and mid 90s and with increasing humidity it will be 100s most afternoons.
The reason for this mid-June sizzle is a large heat dome rising from the west. The jet stream is pushing north, trapping the southeast in a long stretch of hot, humid, foggy afternoons with limited afternoon thunderstorms.
Atlanta has only hit 90° three times this summer so far and our hottest temperature of the year so far was 92° in early June. Not only will we have our hottest temperatures of the upcoming season this week, but we will also be close to some record highs.
We spend an average of 47 days at 90° or more each year in the Peach State capital. The record number of days at this threshold is 91 a few years ago in 2019.

Here’s how the predicted highs against the Heat Index play out day after day. Monday will be the first day that many of us will be able to see this triple-digit heat index. Tuesday and Wednesday look just as warm, but closer to record territory. Tuesday’s daily record is 96°, set in 2016. Wednesday’s daily record is also just 96° since 1952.
With schools closed and summer camp season in full swing, it will be especially important for vulnerable young campers to take breaks from the sun and high heat and to stay hydrated. Those who work outdoors should also be aware of how easily it becomes easy to overwork yourself in this dangerous combination of summer heat and humidity. Know the signs to look for in heat exhaustion and heat stroke.

And for those with furry friends, remember to avoid afternoon walking and avoid paved surfaces. Grassy surfaces stay much cooler in direct sunlight than concrete and asphalt!
