Weather in September
Temperature
September's presence records an average high-temperature of a still warm 27.5°C (81.5°F), closely mirroring August's climate. Libi's average low-temperature is measured at a comfortable 17.5°C (63.5°F) during September.Heat index
September's mean heat index is evaluated at a hot 31°C (87.8°F). Continued exposure and engagement in activity might trigger tiredness and subsequently heat cramps.Consider that heat index readings are for situations in the shade 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', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
