April weather forecast
Rinca, Indonesia

April, like March, in Rinca, Indonesia, is another warm autumn month, with an average temperature ranging between min 23.8°C (74.8°F) and max 28.6°C (83.5°F).

Temperature

April is marked by an average high-temperature of a still warm 28.6°C (83.5°F), maintaining the same climate as March. Rinca maintains an average of approximately a still warm 23.8°C (74.8°F) during April nights, with only a minimal decrease from the daytime temperature.

Heat index

Throughout April, the heat index is computed to be a fiery hot 35°C (95°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Humidity

In Rinca, the average relative humidity in April is 85%.

Rainfall

In Rinca, during April, the rain falls for 25.4 days and regularly aggregates up to 156mm (6.14") of precipitation. Throughout the year, there are 229.6 rainfall days, and 1680mm (66.14") of precipitation is accumulated.

Sunshine

In Rinca, the average sunshine in April is 7.7h.

UV index

January through May, September through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high health risk from unsafe exposure to UV radiation for ordinary individuals.
Note: The maximum UV index of 7 during April translates into these guidelines:
Prevent overexposure. Protection from the sun's harmful effects is needed. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
