Weather in September
Temperature
The start of September comes with a small reduction in the average high-temperature, subtly receding from a hot 91.9°F (33.3°C) in August to a moderately hot 84.4°F (29.1°C). Throughout September, Spearman registers a consistent average low-temperature of 64°F (17.8°C).Heat index
September's mean heat index is computed to be a hot 86°F (30°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.

Prioritize safety - The need to safeguard skin and eyes from harm is emphasized. Midday Sun has the strongest UV rays, making it crucial to limit exposure and find shade. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
