2023 Yearly Climate Review for Memphis, TN

3 min read

Climate Recap

2023 will go into the history books as the fourth warmest year on record in Memphis with near average precipitation for the year. However, those overall statistics do now tell the entire story, particularly with respect to precipitation. Below is a summary of monthly temperature and precipitation data. On average, spring and summer were near to cooler than average. However, the cool season from fall to winter was much warmer than average. This resulted in an overall annual departure from normal of +1.7 degrees. There were 16 warm weather records set in 2023 and no cool temperature records.

On the precipitation side, with the exception of a dry May, precipitation ran above to well above average. The back half of the year, though, saw that surplus disappear, resulting in severe to extreme fall and early winter drought across the metro, and exceptional drought in north MS. In 2023, NWS-Memphis issued 372 Severe Thunderstorm Warnings, 83 Tornado Warnings, and 54 Flash Flood Warnings for their 5-county coverage area over the Mid-South.
