March 2018 Climate Data for Memphis, TN


March Climate Recap

As is typical for early spring in the Mid-South, temperatures fluctuated quite a bit in March, however the monthly average ended up right at average. No records were set despite have high temperatures that ranged from the mid 40s to upper 70s and lows that swung from the near 60 degrees to near freezing. There was one day (13th) with a sub-freezing low temperature (31 degrees). This would have marked the start of the 2018 growing season if it were not for another sub-freezing low in the first week of April!

The trend of heavy precipitation in February continued into the first week of March, as nearly an inch and a half of rain fell in the first five days of the month and the Mississippi River and its tributaries remained high. Much of the rest of the month was dry however, until the last few days when a weather system produced over two inches of rain (and nearly 50% of the total for the month) on the 28th.
