Weather in May
Temperature

For May, the heat index is evaluated at a sweltering 37°C (98.6°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. As body temperatures escalate without effective heat release, one might face dehydration threats.
