Weather in September
Temperature
During September, the average high-temperature is a still hot 30.8°C (87.4°F), maintaining a close resemblance to that of the preceding month. Lamduan temperatures generally rest at a low of 24.3°C (75.7°F) during the September nights.Heat index
In September, the heat index is calculated to be an extremely hot 41°C (105.8°F). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.Heat index specifics point out values are for conditions of shade and a slight breeze. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Persist in precautions and follow sun safety policies. Keeping sunburn at bay is imperative. The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
