Weather in August

August, the last month of the summer in Commerce, is another hot month, with temperature in the range of an average low of 67.1°F (19.5°C) and an average high of 86.2°F (30.1°C).

Temperature

August's arrival registers an average high-temperature of a still tropical 86.2°F (30.1°C), closely aligning with the temperature of the previous month. An average nighttime temperature of 67.1°F (19.5°C) is recorded during August.

Heat index

August's heat index is estimated at a sweltering 98.6°F (37°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
