Weather in May
Temperature
May's average high-temperature stands at a still warm 29.5°C (85.1°F), showing little deviation from April's 29.7°C (85.5°F). May nights cool down to an average low-temperature of 23.3°C (73.9°F).Heat index
Throughout May, the heat index is computed to be a very hot 38°C (100.4°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

A UV Index estimate of 6 to 7 represents a high health hazard from exposure to the Sun's UV rays for average individuals.Note: A maximum UV index of 6 in May translates into the following recommendations:
Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. Remember that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. Make an effort to avoid direct sun exposure during these hours. To best shield against UV radiation, choose sun-safe garments and dependable sunglasses.
