Weather in August
Temperature
Washington sees the highest average temperatures during the months of July and August, peaking at 93°F (33.9°C).Heat index
The heat index value during August is calculated to be a scorching 107.6°F (42°C). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. 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 significant for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Elude overexposure. Fair-skinned people could get burnt in less 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. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
