Compared to August, September registers a minor decrease in rainfall but remains significantly high. Prolonged daylight persists with subtle shifts in temperature, aiding to maintain the warm and humid climate. September's notable climatic feature remains its extended rainfall periods, synonymous with the previous months.

Temperature

September observes an average high-temperature of a still warm 29.3°C (84.7°F), marking an insignificant difference from August's 29°C (84.2°F). Despite a noticeable differential from daytime highs, Beni notes an average nighttime low-temperature of 16.6°C (61.9°F) in September.

Heat index

For September, the heat index is calculated to be a sweltering 35°C (95°F). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

UV index

The months with the highest UV index are January through July, September through December, with an average maximum UV index of 6. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for ordinary individuals.
Note: The daily high UV index of 6 during September translates into the following recommendations:
Stay clear of intense sun exposure. Solar protection is of utmost significance. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
