Weather in April
Temperature
April marks a minor ascent in the average high-temperature, adjusting from March's moderately hot 76.6°F (24.8°C) to a still warm 82.8°F (28.2°C). Keysville experiences an average temperature drop to an enjoyable 63.9°F (17.7°C) during April nights.Heat index
April's heat index is estimated at a tropical 87.8°F (31°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
