Weather in August

August continues the hot summer streak of its predecessor with an average highest temperature remaining at 89.8°F (32.1°C). It replicates the climate conditions of July, marred by high humidity, prolonged daylight, and a substantial amount of sunshine hours. The wave-soaked coastal line remains a vantage point for mixing pleasure with the prevailing warmth. However, the month notes an increase in rainfall, a possible precursor to the impending cooler start of the next season.

Temperature

July and August represent the warmest period, with an average high-temperature of 89.8°F (32.1°C).

Heat index

The heat index value for August is computed to be an extremely hot 107.6°F (42°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
