Weather in August
Temperature
Hartly's shift from July to August is accompanied by an average high-temperature of a still moderately hot 82.4°F (28°C), a slight deviation from 84.4°F (29.1°C). Hartly, in August, experiences an average temperature of 67.6°F (19.8°C) at night.Heat index
August's heat index is evaluated at a hot 89.6°F (32°C). Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.

Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Remember that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. Make an effort to avoid direct sun exposure during these hours. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
