Weather in September
Temperature
The start of September comes with a small reduction in the average high-temperature, subtly receding from a torrid 100.6°F (38.1°C) in August to a hot 93°F (33.9°C). Salineno's average low-temperature in the month of September is recorded at a warm 77.2°F (25.1°C).Heat index
September's average heat index is evaluated at an extremely hot 107.6°F (42°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
