Weather in May
Temperature
May's average high-temperature stands at a still warm 27.3°C (81.1°F), showing little deviation from April's 28.3°C (82.9°F). A steady low-temperature average of 24°C (75.2°F) is logged during May, reflecting a modest dip from daytime readings.Heat index
The heat index value for May is calculated to be a tropical 31°C (87.8°F). If one remains active during constant exposure, it might cause exhaustion and heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
