Weather in July
Temperature
July welcomes an average high-temperature of a still tropical 91.8°F (33.2°C), not much different from the preceding month. In Picayune, the average nighttime temperature during July is a warm 75°F (23.9°C).Heat index
In July, the heat index is calculated to be a burning hot 114.8°F (46°C). Stay on guard: Heat exhaustion and heat cramps are predicted. Ongoing effort can cause heatstroke.Note that heat index values are valued for light wind and location in the shade. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
Humidity
The average relative humidity in July is 75%.Rainfall
In Picayune, in July, it is raining for 22.2 days, with typically 4.65" (118mm) of accumulated precipitation. Throughout the year, there are 178.7 rainfall days, and 38.62" (981mm) of precipitation is accumulated.Snowfall

Sunshine
The average sunshine in July is 10.3h.UV index
May through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for average individuals.Note: In July, the maximum UV index of 7 transforms into these recommendations:
Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
