Weather in August
Temperature
The advent of August sees the average high-temperature at a still warm 83.5°F (28.6°C), subtly shifted from July's 85.6°F (29.8°C). In August, Monrovia reports a consistent average low-temperature of 64.2°F (17.9°C) during the nights.Heat index
The heat index for August is estimated at a hot 91.4°F (33°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
