Weather in August
Temperature
The unfolding of August shows an average high-temperature of a warm 84.7°F (29.3°C), indicating a slight variance from July's 86.4°F (30.2°C). In August, the nighttime temperature lowers to an average of 73°F (22.8°C).Heat index
In August, the heat index is computed to be a hot 93.2°F (34°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
