Temperature

Arari's shift from April to May is accompanied by an average high-temperature of a still tropical 30.3°C (86.5°F), a slight deviation from 30.2°C (86.4°F). Throughout the month of May, Arari expects an average low of 22.5°C (72.5°F).

Heat index

May's heat index is appraised at an extremely hot 42°C (107.6°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are essentially critical for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

UV index

The months with the highest UV index are May, July through November, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high health hazard from unsafe exposure to UV radiation for average individuals.
Note: The maximum daily UV index, 7 in May, converts into the following recommendations:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
