Weather in April
Temperature
April introduces a marginal temperature uplift, with average high-temperatures adjusting from March's 76.8°F (24.9°C) to a still moderately hot 82.8°F (28.2°C). Nighttime temperatures in April average to a comfortable 64°F (17.8°C).Heat index
In April, the heat index is calculated to be a hot 87.8°F (31°C). With ongoing exposure and activity, one might experience weariness, and heat cramps could ensue.Know that the heat index computations account for shaded terrains and slight winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.

Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
