April weather forecast
Riberalta, Bolivia

April symbolizes the dramatic turning point in Riberalta’s weather patterns. There is a consistent decrease in rainfall and humidity, indicating the end of the wet season. An important shift is the reduced precipitation of 108mm (4.25"), almost halving from March's total rainfall.

Riberalta experiences a recorded average high-temperature of a hot 30.4°C (86.7°F) in April, closely aligned with March's 29.8°C (85.6°F). In the month of April, the average temperature dips to an agreeable 21.9°C (71.4°F) during the night.

Heat index

For April, the heat index is computed to be a blisteringly hot 41°C (105.8°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', determines the feeling of heat when you account for the relative humidity. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Deter overexposure. Protecting against the sun's effects is essential. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
