Weather in April
Temperature
April's climate shows a minor adjustment in average high-temperatures to a still moderately hot 80.6°F (27°C) from March's 76.5°F (24.7°C). Surfside documents a consistent average low-temperature of 73.2°F (22.9°C) at night during April.Heat index
The average heat index in April is calculated to be 84.2°F (29°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.Heat index determinations are made taking into account the shade and light air movements. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
