Weather in September
Temperature
The transition to September results in a modest reduction in average high-temperature, moving from a torrid 98.2°F (36.8°C) in August to a hot 92.5°F (33.6°C). During September, North Alamo experiences an average low-temperature of 77.2°F (25.1°C) at night.Heat index
September's heat index is calculated to be a scorching 109.4°F (43°C). Mind: Heat cramps along with heat exhaustion are anticipated. Heatstroke can develop with continued physical activity.Take into consideration that the heat index values are calculated for shade and light wind conditions. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
