Weather in September
Temperature
With the onset of September, a modest change to a still warm 29.7°C (85.5°F) from August's 29.2°C (84.6°F) is noted in high-temperature. Bento Fernandes observes an average nighttime low-temperature of 22.6°C (72.7°F) during the month of September.Heat index
In September, the average heat index is calculated to be a sweltering 35°C (95°F). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.Know that the heat index computations account for shaded terrains and slight winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
