Weather in April
Temperature
With the onset of April, the average high-temperature registers at a still moderately hot 81.1°F (27.3°C), subtly different from March's 80.2°F (26.8°C). April nights reflect a consistent temperature dip to a still warm 74.3°F (23.5°C), a slight descent from daytime peaks.Heat index
During April, the heat index is calculated to be a tropical 86°F (30°C). Staying active during long-term exposure might result in a state of exhaustion and cause heat cramps.One should consider that heat index numbers are for shaded settings and light wind. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
