Weather in April
Temperature
April witnesses a minor rise in the average high-temperature, transitioning from a warm 75.7°F (24.3°C) in March to a still moderately hot 82.2°F (27.9°C). Grand Island observes an average nighttime low-temperature of 63.1°F (17.3°C) during the month of April.Heat index
In April, the average heat index is computed to be a hot 87.8°F (31°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
