What was the climate like in the last reporting period?
The NWS Climate Summary for Metro Atlanta has now been updated with August 2023 numbers.
In an article entitled What is the difference between climate and weather? The National Ocean Service describes the difference as follows:
“The weather is what you see outside on any given day. So, for example, it could be 75 degrees and sunny or it could be 20 degrees with heavy snow. That’s what the weather is.”
“Climate is the average of that weather. For example, you can expect it to snow in the Northeast in January or to be hot and humid in the Southeast in July. That’s the climate. The climate record also includes outliers such as record high temperatures or Record rainfall amounts. If you’ve ever heard your local meteorologist say, “Today we set a record for the day,” she’s talking about climate records.
“So when we talk about climate change, we’re talking about changes in long-term averages of daily weather. In most places, weather can change from minute to minute, hour to hour, day to day, and season to season. Climate is Average weather over time and space.
The Atlanta area climate report for the previous month shows how much of a departure from average temperatures that month represents. The average temperature for a date is the average over a 30-year period.
