Guajará-Mirim in May witnesses an average high-temperature of a still tropical 30.7°C (87.3°F), indicating a slight variation from April's 30.6°C (87.1°F). Throughout May, Guajará-Mirim witnesses a nighttime temperature average of 20.8°C (69.4°F).

Heat index

Throughout May, the heat index is computed to be a blistering 41°C (105.8°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold great significance to children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

In May, the average relative humidity is 82%.

Note: A daily high UV index of 6 in May leads to these guidelines:
Persist with precautions and heed sun safety advice. Prevention of sunburn is compulsory. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck.
