Weather in September
Temperature
The average high-temperature during September is a still tropical 33.7°C (92.7°F), almost matching the conditions of the preceding month. During September, the average low-temperature in Bojonegoro is an agreeable 22.9°C (73.2°F).Heat index
September's heat index is estimated at a scorching 43°C (109.4°F). Stay watchful: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. 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 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
