Weather in September
Temperature
A subtle change in temperatures is noted as August gives way to September, with average highs reducing from a sweltering 97.3°F (36.3°C) to a hot 90.9°F (32.7°C). The low-temperature average for Rancho Alegre during September stands at a warm 75.2°F (24°C).Heat index
Throughout September, the heat index is estimated at an extremely hot 107.6°F (42°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
