Weather in August
Temperature
Wisner experiences its warmest period in July and August, averaging a high-temperature of 91.2°F (32.9°C).Heat index
In August, the heat index is computed to be a blazing hot 113°F (45°C). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
