Weather in May
Temperature
With the onset of May, Wisner's weather sees a minor temperature rise, transitioning from a moderately hot 76.8°F (24.9°C) in April to a still warm 83.8°F (28.8°C). Wisner records an average low of 62.6°F (17°C) throughout the nights in May.Heat index
For May, the heat index is computed to be a tropical 91.4°F (33°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
