Weather in September

September, the first month of the autumn in Bolivia, is still a tropical month, with temperature in the range of an average high of 31.3°C (88.3°F) and an average low of 24.4°C (75.9°F).

Temperature

Transitioning from August to September, Bolivia observes an average high-temperature of a still hot 31.3°C (88.3°F), differing subtly from the previous month. Bolivia's average low-temperature in the month of September is recorded at a moderately hot 24.4°C (75.9°F).

Heat index

The average heat index in September is calculated to be an extremely hot 42°C (107.6°F). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. 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 particularly relevant to children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Humidity

The average relative humidity in September is 81%.

Rainfall

In Bolivia, during September, the rain falls for 20.7 days and regularly aggregates up to 63mm (2.48") of precipitation. In Bolivia, during the entire year, the rain falls for 199.3 days and collects up to 529mm (20.83") of precipitation.

UV index

March through October, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high health risk from unsafe exposure to UV radiation for average individuals.
Note: A typical high UV index of 7 in September suggests the following recommendations:
Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
