Temperature

Bulian's shift from April to May is accompanied by an average high-temperature of a still tropical 31.9°C (89.4°F), a slight deviation from 31.8°C (89.2°F). Throughout May, Bulian records an average temperature of 24.6°C (76.3°F) at night.

Heat index

May's heat index is computed to be a blisteringly hot 44°C (111.2°F). Alert: Heat cramps and heat exhaustion are likely to occur. Prolonged exertion can lead to heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
