Weather in September
Temperature
Inongo's shift into September sets the average high-temperature at a still hot 31.6°C (88.9°F), a figure that deviates only slightly from August's 32.2°C (90°F). Inongo experiences a nighttime temperature average of 22.5°C (72.5°F) during September.Heat index
The heat index for September is appraised at a scorching 41°C (105.8°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Heat index determinations are made taking into account the shade and light air movements. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
