Weather in April
Temperature
The start of April signals a slight increase in the average high-temperature, moving from 23.5°C (74.3°F) in March to a still warm 27.2°C (81°F). In Cao Bang, April is marked by an average low-temperature of 17.8°C (64°F).Heat index
The average heat index in April is calculated to be a hot 30°C (86°F). One might feel worn out with persistent exposure and activity, resulting in heat cramps.Records show heat index calculations are tailored for shaded regions and mild winds. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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.
