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 Barataria is gradually decreasing during the winter, falling from 15% to 12% over the course of the season.

The lowest chance of a muggy day during the winter is 6% on January 23.

For reference, on July 22, the muggiest day of the year, there are muggy conditions 99% of the time, while on January 23, the least muggy day of the year, there are muggy conditions 6% of the time.

Temperature and Dew Point

There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Barataria.

For each station, the records are corrected for the elevation difference between that station and Barataria 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 Barataria is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Barataria and a given station.

The stations contributing to this reconstruction are:
