Weather in May
Temperature
The beginning of May signals a minor rise in the average high-temperature, moving from a moderately hot 74.5°F (23.6°C) in April to a still warm 81.7°F (27.6°C). Throughout May, the temperature tends to fall to a consistent average low of 63°F (17.2°C).Heat index
May's heat index is estimated at a hot 86°F (30°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.For clarity, heat index numbers account for light winds and areas under shade. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
