Weather in August
Temperature
With the onset of August, the average high-temperature stands at a still hot 87.3°F (30.7°C), closely aligned with July's 88.3°F (31.3°C). The average nighttime temperature lowers to a pleasant 70.2°F (21.2°C) throughout August.Heat index
In August, the heat index is computed to be a very hot 102.2°F (39°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Realize that the values for the heat index are set for shaded places and light winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
Humidity
May, August and September, with an average relative humidity of 77%, are the most humid months.Rainfall

Sunshine
The average sunshine in August is 10.3h.UV index
In August, the average daily maximum UV index is 6. A UV Index value of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV radiation for the average person.Note: In August, a daily UV index of 6 turns into the following recommendations:
Deflect overexposure. Sun protection is a necessity. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
