Weather in April
Temperature
April's arrival is noted with a slight increase in the average high-temperature, moving from a warm 75.7°F (24.3°C) in March to a still moderately hot 82°F (27.8°C). An average low-temperature of 65.8°F (18.8°C) marks the month of April.Heat index
Throughout April, the heat index is calculated to be a hot 86°F (30°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
