Weather in April

April, the same as March, in Patos, Brazil, is a hot autumn month, with an average temperature varying between 31.8°C (89.2°F) and 21.2°C (70.2°F).

Temperature

The onset of April brings an average high-temperature of a still hot 31.8°C (89.2°F), nearly matching the March temperature. Patos experiences an average low-temperature of 21.2°C (70.2°F) in the month of April.

Heat index

In April, the heat index is calculated to be a scorching 41°C (105.8°F). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. 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 'real feel' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Humidity

The average relative humidity in April is 72%.

Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades.
