Weather in May

In May, the heat index is evaluated at a very hot 95°F (35°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. 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. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
