Weather in May
Temperature
The shift into May uncovers an average high-temperature of a still moderately hot 28.1°C (82.6°F), subtly different from the previous month. Throughout May, a steady low-temperature average of 19.6°C (67.3°F) is noted.Heat index
May's mean heat index is appraised at a tropical 34°C (93.2°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical 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.

Limit direct exposure to the Sun during these hours. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
