Weather in May
Temperature
The shift into May reveals an average high-temperature of a still moderately hot 27.8°C (82°F), closely mirroring April's climate. In the month of May, the average low-temperature usually rests at a refreshing 17.8°C (64°F).Heat index
During May, the heat index is estimated at a hot 31°C (87.8°F). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.In reference to the heat index, it's for places in shade and with a slight wind. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
