Weather in April

April signals the beginning of the dry season in Rundu, reflected in a noteworthy drop in rainfall. The city’s average rainfall dips from 39mm (1.54") in March to just 22mm (0.87") in April, signifying the arrival of a drier climate. With this decrease in rainfall, temperatures also fall, and the city moves towards a cooler and semi-arid climate. As summer winds down, Rundu welcomes longer daylight hours and a general rise in atmospheric pressure. These transformations prompt a shift in the city’s climate from the warmer summer months to a cooler, arid season.

April's onset in Rundu brings an average high-temperature of a still warm 28.9°C (84°F), showing a minute difference from March's 29.7°C (85.5°F). During the nights in April, the temperature in Rundu averages to a comfortable 17.2°C (63°F).

Heat index

The average heat index in April is calculated to be a hot 30°C (86°F). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.
Data suggests that the heat index is set for environments in shade and with a light wind. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
