Weather in September
Temperature
The arrival of September sees an average high-temperature of a still tropical 86.9°F (30.5°C), hardly diverging from August's 91.9°F (33.3°C). In September, Warren encounters an average low-temperature of 66°F (18.9°C) during the night.Heat index
For September, the heat index is estimated at a sweltering 98.6°F (37°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Be informed that the heat index values are oriented around shady conditions and gentle breezes. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. 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 essentially critical for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage.
