Weather in May
Temperature
Grapeland's May weather indicates a minor ascent in high-temperatures, adjusting from a moderately hot 77.4°F (25.2°C) in April to a still warm 84.9°F (29.4°C). May's nights observe an average temperature of 64°F (17.8°C).Heat index
May's heat index is calculated to be a very hot 95°F (35°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
