Weather in September
Temperature
A mild drop in Pearsall's average high-temperature is observed in September, transitioning from a very hot 98.2°F (36.8°C) in August to a tropical 90.7°F (32.6°C). The nighttime temperature dips to an agreeable 72.7°F (22.6°C) on average during September.Heat index
The average heat index in September is estimated at a blisteringly hot 104°F (40°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.Records show heat index calculations are tailored for shaded regions and mild winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Sunshine
In September, the average sunshine is 8.4h.UV index
The average daily maximum UV index in September is 6. A UV Index estimate of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for ordinary individuals.Note: The maximum UV index of 6 during September translates into these guidelines:
Take precautions and adopt sun safety practices. Protection against sunburn is obliged. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
