Weather in August
Temperature
The advent of August observes an average high-temperature of a still hot 86.9°F (30.5°C), nearly identical to July's 87.8°F (31°C). August generally records an average low-temperature of 67.6°F (19.8°C).Heat index
August's heat index is calculated to be a fiery hot 100.4°F (38°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
Humidity
In Overall, the average relative humidity in August is 75%.Rainfall
In Overall, in August, during 13.3 rainfall days, 1.26" (32mm) of precipitation is typically accumulated. In Overall, during the entire year, the rain falls for 123.1 days and collects up to 12.76" (324mm) of precipitation.Snowfall

Sunshine
The average sunshine in August is 10.4h.UV index
The months with the highest UV index are May through August, with an average maximum UV index of 6. A UV Index of 6 to 7 symbolizes a high threat to health from unsafe exposure to UV radiation for the ordinary person.Note: The UV index of 6 during August leads to these advisories:
Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
