Weather in April
Temperature
Osicala's warmest season falls during March and April, averaging a high-temperature of 35.1°C (95.2°F).Heat index
Throughout April, the heat index is appraised at a burning hot 46°C (114.8°F). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.Bear in mind that the heat index values are determined for shaded areas and light breezes. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. 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 hold particular significance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
