Temperature

The transition from April to May brings an average high-temperature of a tropical 30.6°C (87.1°F), barely different from April's 29.7°C (85.5°F). Tapanã's nighttime temperature during May is consistently averaged at a moderately hot 23.4°C (74.1°F).

Heat index

The heat index value for May is appraised at an extremely hot 42°C (107.6°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. 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.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. As body temperatures escalate without effective heat release, one might face dehydration threats.

Humidity

In May, the average relative humidity is 88%.

UV index

May, July through October and December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for the average person.
Note: In May, the maximum UV index of 7 transforms into these recommendations:
Embrace precautions and observe sun safety norms. Evasion of sunburn is a necessity. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
