Weather in September
Temperature
With September's advent, Nsawkaw sees an average high-temperature of a still moderately hot 29.1°C (84.4°F), subtly shifted from August's 28.9°C (84°F). An average low-temperature of 21.7°C (71.1°F) is recorded during the nights in September.Heat index
For most parts of September, the heat index is computed to be a torrid 37°C (98.6°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.In terms of the heat index, values are set with light wind and shade conditions in mind. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
