Weather in May
Temperature
As Martha transitions into May, the average high-temperature is observed to slightly rise from 73.9°F (23.3°C) in April to a still moderately hot 82.6°F (28.1°C). In May, the average low-temperature is a comfortable 61.5°F (16.4°C).Heat index
May's average heat index is estimated at a tropical 86°F (30°C). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.When referencing the heat index, its values are suitable for shady environments and light breezes. 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 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
