The first month of the summer, June, is a hot month in Decatur, Mississippi, with an average temperature varying between 69.8°F (21°C) and 90.5°F (32.5°C).

Temperature

Decatur's transition into June brings a slight rise in the average high-temperature, moving from a warm 83.5°F (28.6°C) in May to a tropical 90.5°F (32.5°C). Decatur usually reports an average low-temperature of 69.8°F (21°C) during the month of June.

Heat index

For June, the heat index is computed to be an extremely hot 109.4°F (43°C). Mind: Heat cramps along with heat exhaustion are anticipated. Heatstroke can develop with continued physical activity.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

In June, the average relative humidity is 73%.

Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Boost your sun resistance with garments that are densely woven yet spacious.
