Weather in September
Temperature
Watson transitions into September recording an average high-temperature of a moderately hot 85.3°F (29.6°C), closely aligning with the preceding month's temperature. During the nights in September, Watson observes an average low-temperature of 66.7°F (19.3°C).Heat index
During September, the heat index is computed to be a torrid 95°F (35°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
