Manacapuru, Brazil, marks the onset of June with an average high-temperature of a still tropical 31.3°C (88.3°F), a subtle shift from May's 30.2°C (86.4°F). Throughout June, Manacapuru registers a consistent average low-temperature of 22.8°C (73°F).

Heat index

The heat index value during June is calculated to be an extremely hot 42°C (107.6°F). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Guard oneself from overexposure. Defence against sun injury is vital. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays.
