Weather in May
Temperature
The average high-temperature is a still moderately hot 29.8°C (85.6°F) in May, consistent with April. An average low-temperature of 21.9°C (71.4°F) marks the month of May.Heat index
May's average heat index is evaluated at a blistering 40°C (104°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
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. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
