Weather in August

Temperature

Roseland's warmest month, August, generally records average temperatures ranging from a high of 87.1°F (30.6°C) to a low of 79°F (26.1°C).

Heat index

August's mean heat index is calculated to be a fiery hot 102.2°F (39°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. 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.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
