Weather in April
Temperature
In Iona, the average high-temperature in April slightly increases from a moderately hot 75.7°F (24.3°C) in March to a still warm 81.1°F (27.3°C). Iona, during the month of April, experiences an average low-temperature of 69.1°F (20.6°C).Heat index
The heat index in April is evaluated at a tropical 86°F (30°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Realize that the values for the heat index are set for shaded places and light winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. 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.
Humidity
In April, the average relative humidity is 72%.Rainfall

Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. The Sun's UV radiation is most intense from 10 a.m. to 4 p.m. Try to avoid direct sun exposure during these hours. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure. Heads up! Sand and water reflection magnifies the UV exposure from the Sun.
