Weather in September
Temperature
With the onset of September, a modest change to a still hot 86.5°F (30.3°C) from August's 91°F (32.8°C) is noted in high-temperature. Spencer observes an average low-temperature of 66.9°F (19.4°C) during September nights.Heat index
During September, the heat index is evaluated at a torrid 96.8°F (36°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Know that the heat index computations account for shaded terrains and slight winds. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. 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 highly important for children. 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.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial.
