Weather in May

The last month of the autumn, May, is another tropical month in Meruoca, Brazil, with an average temperature fluctuating between 30.4°C (86.7°F) and 21.6°C (70.9°F).

Temperature

May denotes a minimal variation in the average high-temperature to a still tropical 30.4°C (86.7°F) from April's 30.3°C (86.5°F). Throughout the nights in May, an average low-temperature of 21.6°C (70.9°F) is noted.

Heat index

May's heat index is calculated to be an extremely hot 40°C (104°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for 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.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
