Weather in September
The first month of the spring, September, is still a hot month in Orocó, Brazil, with an average temperature fluctuating between 20.8°C (69.4°F) and 32.2°C (90°F).Temperature
September ushers in an average high-temperature of a still tropical 32.2°C (90°F), aligning closely with the preceding month. In September, the nighttime temperature lowers to an average of 20.8°C (69.4°F).Heat index
The heat index in September is computed to be a torrid 36°C (96.8°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
