September weather forecast
Keret, Indonesia

The first month of the spring, September, is also a hot month in Keret, Indonesia, with an average temperature fluctuating between 22.4°C (72.3°F) and 33.6°C (92.5°F).

Temperature

September's weather displays an average high-temperature of a still hot 33.6°C (92.5°F), slightly varied from August's 32.3°C (90.1°F). Keret's average low-temperature is measured at a pleasant 22.4°C (72.3°F) during September.

Heat index

September's heat index is computed to be an extremely hot 42°C (107.6°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. 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. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
