Weather in May
Temperature
May witnesses a minor rise in the average high-temperature, transitioning from 78.4°F (25.8°C) in April to a still warm 84.7°F (29.3°C). Geismar's average low-temperature for the month of May records at a comfortable 66°F (18.9°C).Heat index
For May, the heat index is calculated to be a fiery hot 95°F (35°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
