Weather in April
Temperature
A slight uplift in the average high-temperature marks April, adjusting from March's moderately hot 74.8°F (23.8°C) to a still warm 81.1°F (27.3°C). During April, an average low-temperature of 61.3°F (16.3°C) is observed.Heat index
April's mean heat index is appraised at a hot 86°F (30°C). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. 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 particularly relevant to children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
