Weather in September
Temperature
The commencement of September introduces an average high-temperature of a tropical 31.8°C (89.2°F), closely mirroring the preceding month. Curral Velho measures a considerable dip from daytime highs with an average low-temperature of 18.9°C (66°F) during September.Heat index
For September, the heat index is appraised at a torrid 36°C (96.8°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
