Weather in April
Temperature
As April unfolds, the average high-temperature reaches a warm 29.7°C (85.5°F), hinting at a slight fluctuation from the previous month. During April, the average low-temperature is a pleasant 20.8°C (69.4°F).Heat index
During April, the heat index is computed to be a very hot 38°C (100.4°F). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.When assessing, remember that heat index measurements are for light winds and shaded spots. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
