With April's advent, Barrocas sees an average high-temperature of a still hot 31°C (87.8°F), subtly shifted from March's 32.8°C (91°F). Barrocas, in the month of April, anticipates a consistent average low-temperature of 21.3°C (70.3°F).

Heat index

The average heat index in April is estimated at an extremely hot 40°C (104°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.

Humidity

In April, the average relative humidity in Barrocas is 77%.

UV index

Note: The daily maximum UV index of 6 in April interprets into the following advice:
Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
