Weather in August
Temperature
With the advent of August, Washington experiences an average high-temperature of a still hot 87.1°F (30.6°C), mirroring a close resemblance to the previous month. Washington observes an average nighttime temperature of 65.8°F (18.8°C) during August.Heat index
August's mean heat index is calculated to be a fiery hot 100.4°F (38°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. 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.

Follow precautions and abide by sun safety rules. Deterrence of sunburn is imperative. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
