However, it also experiences a slight increase in rainfall, signaling the subtle approach of the wet season. August suspends the city in an interesting weather dynamic, creating a bridge between the apex of the dry season and the deemed return of rainfall. The combination of high heat and imminent rain showers provide a distinctive blend of weather characteristics challenging to predict.

Temperature

The arrival of August in Riberalta marks a slight shift to an average high-temperature of a very hot 35.2°C (95.4°F) from July's 32.7°C (90.9°F). Riberalta anticipates a pronounced temperature drop from daily highs during the nights of August, with an average low of 20.6°C (69.1°F).

Heat index

August's average heat index is computed to be an extremely hot 42°C (107.6°F). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
