Weather in May
Temperature
Brazil experiences a minor change to a still moderately hot 29.4°C (84.9°F) in average high-temperature during May, closely reflecting April. May registers an average low temperature of 26°C (78.8°F), subtly lower than the daytime maximum.Heat index
The heat index for May is evaluated at a very hot 35°C (95°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for the average person.Note: A maximum UV index of 7 in May translates into the following recommendations:
Guard against overexposure. Protection from sun-induced harm is essential. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
