Temperature

Mariana's temperatures peak on average in May, reaching 33.3°C (91.9°F) at their highest and 26.4°C (79.5°F) at their lowest.

Heat index

In May, the heat index is evaluated at a life-threatening hot 45°C (113°F). Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Note: The maximum daily UV index of 7 in May converts into the following recommendations:
Fend off overexposure. Sun protection is vital. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
