Weather in May
Temperature
The onset of May marks an average high-temperature of a still warm 27.3°C (81.1°F), hardly differing from April's 26.3°C (79.3°F). Butlers's nocturnal May readings average at a still warm 26.5°C (79.7°F), showing little variation from the daytime temperatures.Heat index
In May, the average heat index is computed to be a tropical 30°C (86°F). Fatigue might occur with continuous exposure and activity, potentially causing heat cramps.Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
