May weather forecast
Luís Correia, Brazil

May, the last month of the autumn in Luís Correia, is another tropical month, with an average temperature varying between 30.7°C (87.3°F) and 24.6°C (76.3°F).

Temperature

A minimal variation is noted in Luís Correia's average high-temperature at the onset of May, reaching a still tropical 30.7°C (87.3°F) from April's 30.6°C (87.1°F). In May, Luís Correia experiences an average nighttime temperature of 24.6°C (76.3°F).

Heat index

During May, the heat index is estimated at a scorching 40°C (104°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Humidity

The months with the highest humidity are April and May, with an average relative humidity of 81%.

UV index

January through December, with an average maximum UV index of 7, are months with the highest UV index. The months with the lowest UV index in Luís Correia are January through December, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for average individuals.
Note: The UV index of 7 in May translates into these instructions:
Prevent overexposure. Protection from the sun's harmful effects is needed. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat. Take note! Sand and water reflections strengthen the Sun's UV exposure.
