Weather in August

Focusing on Florence's weather in August, the heat wave that initiated in July continues with barely any respite. The reduced sunshine hours prove deceptive as temperatures remain significantly high, showing a negligible cooling from the previous month. However, a unique characteristic in August compared to July is a noticeable increase in cloud cover. Despite the high temperatures, the month offers the lowest average wind speeds of the calendar year. The rainfall this month also reaches a high, witnessing a record 3.82" (97mm).

Temperature

Florence commences August with an average high-temperature of a still hot 88.3°F (31.3°C), maintaining a close resemblance to the previous month. In the month of August, the temperature generally rests at an average low of 71.2°F (21.8°C).

Heat index

August's heat index is estimated at an extremely hot 105.8°F (41°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
