Weather in April
April marks a significant drop in both temperature and rainfall. Rain showers decrease dramatically to a minimal 19mm (0.75"), while temperatures experience a minimal reduction. The decrease in cloud cover allows for increased sunshine, averaging 9.4 hours daily. Although wind speeds now peak, their maximum speed is around just 10.7km/h (6.6mph), reducing as the month progresses. With the decline in rainfall, April lays down the transition from a warm, wet summer to a cooler, drier winter in Ruacana.Temperature
The advent of April observes an average high-temperature of a still hot 30.1°C (86.2°F), nearly identical to March's 30.2°C (86.4°F). During April, Ruacana witnesses a consistent average low-temperature of 20.1°C (68.2°F).Heat index
For most parts of April, the heat index is computed to be a tropical 31°C (87.8°F). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
