Weather in September
Temperature
The beginning of September records an average high-temperature of a still hot 33.5°C (92.3°F), marking a negligible difference from August's 33.2°C (91.8°F). Miraíma experiences an average low-temperature reading of 23.5°C (74.3°F) throughout September.Heat index
September's mean heat index is calculated to be a blistering 42°C (107.6°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Understand that the heat index values take into account shaded locations and mild winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

A UV Index estimate of 6 to 7 represents a high health hazard from exposure to the Sun's UV rays for ordinary individuals.Note: The maximum UV index of 7 during September leads to these instructions:
Embrace precautions and observe sun safety norms. Evasion of sunburn is a necessity. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
