Weather in August

August generally offers a continuation of July’s weather traits. The sweltering weather modifies marginally however, with a slight decrease in average temperature. The sea temperature peaks this month, then begins its slow descent into cooler figures. Despite this decrease in average temperatures, August typically experiences an increased number of rainy days, with rainfall amounts exceeding those of the previous month. August stands as a representative of the passing summer season, signalled by the gradual decrease in daylight hours.

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.
