The arrival of May sees an average high-temperature of a tropical 30.3°C (86.5°F), hardly diverging from April's 29.7°C (85.5°F). May nights observe an average temperature dip to a pleasant 22.6°C (72.7°F).

Heat index

May's average heat index is evaluated at an extremely hot 42°C (107.6°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
