Weather in May
Temperature
May's arrival coincides with a subtle temperature rise, moving from April's 73.9°F (23.3°C) to a still warm 80.6°F (27°C). An average low-temperature of 63.1°F (17.3°C) is observed during May nights.Heat index
May's average heat index is evaluated at a tropical 86°F (30°C). Prolonged activity during exposure might result in a state of fatigue and cause heat cramps.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', determines the feeling of heat when you account for the relative humidity. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
