Weather in September
Temperature
Barayong experiences a subtle adjustment in high-temperatures to a still hot 30.7°C (87.3°F) with the onset of September, maintaining near parity with August's 31.1°C (88°F). During the month of September, Barayong experiences a steady low-temperature average of 24°C (75.2°F).Heat index
The heat index value during September is computed to be an extremely hot 40°C (104°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Be aware that heat index ratings are designed for shaded locations and minor breezes. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. 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.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for the ordinary person.Note: In September, the maximum UV index of 7 transforms into these recommendations:
Resist extreme sun exposure. Guarding against solar damage is essential. 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. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
