Weather in August
Temperature
The arrival of August brings an average high-temperature of a still moderately hot 81°F (27.2°C), subtly diverging from July's 82°F (27.8°C). Westwood records an average nighttime low-temperature of 62.8°F (17.1°C) throughout August.Heat index
The heat index in August is estimated at a hot 86°F (30°C). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Realize that the values for the heat index are set for shaded places and light winds. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. 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. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
