Weather in April

As Natal moves into April, the weather starts to shift slightly. A noticeable decline in the amount of rainfall, now at 131mm (5.16"), signals the beginning of a drier season. April generally maintains a uniform climatic rhythm with its predecessor March, with slight differences in temperature and sunshine hours. A minor increase in relative humidity points towards a higher atmospheric moisture content, providing fertile conditions for afternoon showers. Yet, with sea temperatures remaining consistent, any outdoor activities in the water are still very much on the cards.

Temperature

Natal records an average high-temperature of a still hot 30°C (86°F) in April, closely mirroring the climate of the previous month. In Natal, April is characterized by an average low-temperature of 25.8°C (78.4°F), indicating a minor drop from daytime highs.

Heat index

The average heat index in April is calculated to be a fiery hot 37°C (98.6°F). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.
The standards for the heat index are set for locations in shade and under light breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Humidity

In April, the average relative humidity is 77%.

January through December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index of 6 to 7 symbolizes a high health vulnerability from unprotected exposure to Sun's UV rays for average individuals.
Note: The UV index of 7 during April leads to these advisories:
Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear. Caution! The reflection of sand and water significantly amplifies the Sun's UV radiation.
