June 2022 climate summary for Atlanta area

The NWS climate summary for metro Atlanta has now been updated with June figures.

In an article entitled What is the Difference between Climate and Weather?, the National Ocean Service describes the difference as follows:

Weather is what you see outside on any particular day. So, for example, it may be 75° degrees and sunny or it could be 20° degrees with heavy snow. That’s the weather.

Climate is the average of that weather. For example, you can expect snow in the Northeast in January or for it to be hot and humid in the Southeast in July. This is climate. The climate record also includes extreme values such as record high temperatures or record amounts of rainfall. If you’ve ever heard your local weather person say “today we hit a record high for this day,” she is talking about climate records.

So when we are talking about climate change, we are 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, however, is the average of weather over time and space.

The climate report for the Atlanta area for the previous month shows how much departure from the average temperatures that month represents. The average temperature for a date is the average over a 30-year period.
