Weather in May
Temperature
May's arrival coincides with a marginal rise in the average high-temperature, moving from April's 77.7°F (25.4°C) to a still moderately hot 84.7°F (29.3°C). May nights cool down to an average low-temperature of 63.7°F (17.6°C).Heat index
Throughout May, the heat index is computed to be a tropical 93.2°F (34°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
