Weather in September
Temperature
With the arrival of September, Westhoff experiences a modest decline in average high-temperatures, transitioning from a torrid 95.9°F (35.5°C) in August to a tropical 89.2°F (31.8°C). In Westhoff, September nights witness a steady temperature drop to a pleasant 72.5°F (22.5°C).Heat index
The heat index for September is evaluated at a scorching 105.8°F (41°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.When referencing the heat index, its values are suitable for shady environments and light breezes. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'feels like' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
