Cloud Cover in January
A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Enterprise, the chance of a wet day over the course of January is gradually increasing, starting the month at 29% and ending it at 32%.
For reference, the year's highest daily chance of a wet day is 54% on July 18, and its lowest chance is 18% on October 16.
Probability of Precipitation in January
To show variation within the month and not just the monthly total, we show the rainfall accumulated over a sliding 31-day period centered around each day.
The average sliding 31-day rainfall during January in Enterprise is gradually increasing, starting the month at 4.4 inches, when it rarely exceeds 7.5 inches or falls below 1.8 inches, and ending the month at 4.8 inches, when it rarely exceeds 7.6 inches or falls below 2.1 inches.
Average Monthly Rainfall in January
Over the course of January in Enterprise, the length of the day is increasing. From the start to the end of the month, the length of the day increases by 32 minutes, implying an average daily increase of 1 minute, 4 seconds, and weekly increase of 7 minutes, 29 seconds.
The shortest day of the month is January 1, with 10 hours, 10 minutes of daylight and the longest day is January 31, with 10 hours, 42 minutes of daylight.
Hours of Daylight and Twilight in January
The latest sunrise of the month in Enterprise is 6:43 AM on January 8 and the earliest sunrise is 7 minutes earlier at 6:36 AM on January 31.
The earliest sunset is 4:52 PM on January 1 and the latest sunset is 26 minutes later at 5:17 PM on January 31.
Daylight saving time is observed in Enterprise during 2017, but it neither starts nor ends during January, so the entire month is in standard time.
For reference, on June 21, the longest day of the year, the Sun rises at 5:39 AM and sets 14 hours, 11 minutes later, at 7:50 PM, while on December 21, the shortest day of the year, it rises at 6:38 AM and sets 10 hours, 7 minutes later, at 4:45 PM.

We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.
The chance that a given day will be muggy in Enterprise is essentially constant during January, remaining within 1% of 2% throughout.
The lowest chance of a muggy day during January is 1% on January 31.
For reference, on July 23, the muggiest day of the year, there are muggy conditions 97% of the time, while on January 24, the least muggy day of the year, there are muggy conditions 1% of the time.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.
The average hourly wind speed in Enterprise is essentially constant during January, remaining within 0.1 miles per hour of 3.1 miles per hour throughout.
For reference, on February 25, the windiest day of the year, the daily average wind speed is 3.3 miles per hour, while on August 6, the calmest day of the year, the daily average wind speed is 2.1 miles per hour.

Enterprise is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water.
The average surface water temperature in Enterprise is gradually decreasing during January, falling by 2°F, from 65°F to 63°F, over the course of the month.

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.
The average daily incident shortwave solar energy in Enterprise is gradually increasing during January, rising by 0.6 kWh, from 3.0 kWh to 3.6 kWh, over the course of the month.

This report illustrates the typical weather in Enterprise year round, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Enterprise.
For each station, the records are corrected for the elevation difference between that station and Enterprise according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at Enterprise is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Enterprise and a given station.
The stations contributing to this reconstruction are: Fort Rucker, Lowe Army Heliport (53%, 11 kilometers, northeast); Cairns Army Airfield (Fort Rucker) (37%, 14 kilometers, east); Andalusia, Andalusia-Opp Municipal Airport (5%, 51 kilometers, west); and Florala Municipal Airport (5%, 53 kilometers, southwest).
All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.
All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.
