Weather in May
Temperature
The shift into May is marked by a modest rise in the average high-temperature, moving from April's warm 73.9°F (23.3°C) to a still moderately hot 82°F (27.8°C). Throughout the nights in May, an average low-temperature of 61.9°F (16.6°C) is noted.Heat index
The heat index in May is computed to be a hot 87.8°F (31°C). Remaining active during long-lasting exposure could cause fatigue, leading to heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
