Weather in September
Temperature
As September takes hold, the average high-temperature is a still tropical 33.5°C (92.3°F), nearly mirroring that of the previous month. Senador Pompeu's nighttime temperature in September demonstrates a noticeable plunge to a pleasant 21.1°C (70°F).Heat index
The heat index for September is evaluated at a torrid 38°C (100.4°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Be informed that the heat index values are oriented around shady conditions and gentle breezes. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

A UV Index reading of 6 to 7 represents a high health risk from unprotected exposure to Sun's UV rays for the ordinary person.Note: The daily high UV index of 7 in September translates into this advice:
Prevent overexposure. Protection from the sun's harmful effects is needed. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection.
