What was the climate like in the last reporting period?

The NWS climate summary for the Atlanta metropolitan area has now been updated with July 2024 figures.

In an article titled “What is the difference between climate and weather?” the National Ocean Service describes the difference as follows:

“Weather is what you see outside on a given day. For example, it could be 24°C and sunny, or -6°C and heavy snowfall. That's the weather.”

“Climate is the average of that weather. For example, you can expect snow in the northeast in January or heat and humidity in the southeast in July. That's climate. Climate records also include extremes such as record temperatures or record rainfall. If you've ever heard your local weather report say, “Today we hit a record for this day,” they're talking about climate records.

“So when we talk about climate change, we're talking about changes in the long-term averages of daily weather. In most places, the weather can change from minute to minute, hour to hour, day to day, and season to season. Climate, on the other hand, is the average of the weather over time and space.”

The climate report for the Atlanta region for the previous month shows how much the deviation is from the average temperatures of that month. The average temperature for a date is the average over a period of 30 years.
