Weather in September
Temperature
The commencement of September brings an average high-temperature of a still hot 87.3°F, marking an inconsequential divergence from August. During September, Alachua records an average temperature of 72°F at night.Heat index
September's average heat index is evaluated at a sweltering 102.2°F. Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.Heat index specifics point out values are for conditions of shade and a slight breeze. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for 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.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
