Weather in April
Temperature
The average temperatures reach their apex in April, averaging 32.9°C (91.2°F) at the high end and 22°C (71.6°F) at the low end.Heat index
April's mean heat index is evaluated at a blazing hot 46°C (114.8°F). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.When assessing, remember that heat index measurements are for light winds and shaded spots. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
