Weather in September
Temperature
In Uarini, September is identified by the highest average temperatures, reaching a peak of 34.7°C (94.5°F) and a low of 23.2°C (73.8°F).Heat index
In September, the heat index is calculated to be a life-threatening hot 49°C (120.2°F). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.Be advised, the heat index considers values for conditions in shade and with a light breeze. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
