Weather in August
Temperature
The beginning of August reveals an average high-temperature of a still moderately hot 82.2°F (27.9°C), showing minimal deviation from the previous month. During the month of August, an average temperature of 63.9°F (17.7°C) is noted during the nights.Heat index
The heat index value for August is evaluated at a hot 89.6°F (32°C). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. 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.

Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory.
