Weather in September
Temperature
September brings an average high-temperature of a still hot 87.8°F (31°C), showing a slight difference from August's 91.9°F (33.3°C). Throughout the month of September, Toomey witnesses an average temperature of 72.1°F (22.3°C).Heat index
Throughout September, the heat index is estimated at a blistering 104°F (40°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular importance for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
