Weather in September
Temperature
Ananás notes the warmest temperatures in September, with a high average of 36.5°C (97.7°F) and a low of 23.1°C (73.6°F).Heat index
For most parts of September, the heat index is calculated to be a blisteringly hot 43°C (109.4°F). Stay alert: Heat cramps and heat exhaustion are expected. Heatstroke is a likely outcome of ongoing activity.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened 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. Protection against sun damage is needed. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
