Weather in April
Temperature
With the onset of April, the average high-temperature subtly transitions from 76.5°F (24.7°C) in March to a still warm 82.6°F (28.1°C). April sees the temperature falling to a mean low of 64.6°F (18.1°C).Heat index
The heat index for April is calculated to be a hot 87.8°F (31°C). Staying active during long-term exposure might result in a state of exhaustion and cause heat cramps.It is emphasized that the heat index's values are meant for shaded zones with mild winds. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
