The biggest surprise for visitors to Natchez is the climate. If you like four seasons of the year, Natchez will suit you well. There is a definite summer, fall, winter and spring pattern in the area. While some may argue that our summers are hot — the average high temperature in July is 91.8 degrees — most summer days do not reach the extremes for which the Deep South is known.
Summer may seem the longest season and comes closest to being an “extreme” season. June, July and August have average temperatures of 90 and above, and May ranges in the mid to high 80s, as does September.
Oh, but wait for October. The clear blue skies come with mild temperatures that may rise into the 80s but are generally in the 70s. Natchez has a good reputation for beautiful fall weather.
First frost can come as early as November, but real wintry weather is most likely in January and February, as a rule. January is the coldest month, with high temperatures hovering at about 60.
The mild beautiful days in the winter months erase any misery that an occasional day or two of ice or freezing rain may bring.
The winters are made colorful by the beautiful red, pink, purple and variegated camellias that bloom in the winter months.
Natchez winters are influenced by the Gulf of Mexico to the south, the continental land mass and the prevailing southerly wind, to be technical about it.
The southerly winds provide a moist semitropical climate that makes afternoon thunderstorms likely — and numerous.
Although the days of high humidity from May well into the fall occasionally are uncomfortable, the afternoon rains are a relief.
In April, the average high temperature is about 78 degrees as compared to 92 in August. The average April low is about 55 as compared to 70 in August.
In the summertime, maximum average temperatures are in the 80s and 90s. In the winter, frequent warm tropical fronts break the spell of cold.
Cold spells rarely last longer than a few days, and hard freezes are not frequent. Ice storms and occasional snowfalls can occur, typically in the months of January and February.
Because of the area’s humidity and average temperatures, snowfall rarely accumulates at more than an inch and often melts off the same day.
On the other hand, Natchez weather is subject to rapid changes in the fall and winter, with sudden drops in temperature that can take a person from short sleeves one day into the woolen coat the next.
In the wintertime, Natchez averages only about 21 days of temperatures below 32 degrees. Normal daily lows average in the 40s.
By late March, flowering trees and shrubs generally are in full bloom.
