Weather in May
Temperature
May showcases a minor temperature ascent, adjusting from April's warm 74.8°F (23.8°C) to a still moderately hot 81.9°F (27.7°C). Nighttime temperature dips to a mean of 69.8°F (21°C) during May.Heat index
May's mean heat index is calculated to be a tropical 87.8°F (31°C). If one remains active during constant exposure, it might cause exhaustion and heat cramps.Consider that heat index readings are for situations in the shade and light wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
