Weather in August
Temperature
August's climate shows a minor adjustment in average high-temperatures to a still hot 88.7°F (31.5°C) from July's 91°F (32.8°C). The month of August records an average low-temperature of 69.4°F (20.8°C).Heat index
The heat index in August is estimated at a sweltering 102.2°F (39°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Research indicates the heat index considers values in shaded locales and with light 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 'real feel' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
Humidity
In August, the average relative humidity is 70%.Rainfall
August is the month with the most rainfall. Rain falls for 16 days and accumulates 3.23" (82mm) of precipitation.Snowfall

Sunshine
The average sunshine in August is 10.2h.UV index
The average daily maximum UV index in August is 6. A UV Index reading of 6 to 7 represents a high threat to health from exposure to the Sun's UV rays for the average person.Note: The daily high UV index of 6 during August translates into the following recommendations:
Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
