Weather in September
Temperature
In Layou, September is the month with the highest recorded average temperatures, measuring a high of 28.7°C (83.7°F) and a low of 27.9°C (82.2°F).Heat index
For most parts of September, the heat index is computed to be a hot 33°C (91.4°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.One should consider that heat index numbers are for shaded settings and light wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular 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.

Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects. Heads up! Sand and water reflection magnifies the UV exposure from the Sun.
