In August, the climate conditions of Leavenworth, Kansas see a slight dip in temperature values from July. It positions August within the transitional phase between the stifling summer heat and the forthcoming mild fall temperatures. Climatologically, August continues to ride the summer wave, with temperatures still averaging within 80s°F. Fluctuation occurs in terms of humidity, rainfall and cloud cover, introducing variability within the weather pattern. However, the city continues to enjoy an elongated duration of daylight and prolonged hours of sunshine.

Temperature

The shift from July to August in Leavenworth is characterized by an average high-temperature of a warm 84.6°F (29.2°C), not significantly different from the 86.4°F (30.2°C) of July. In the month of August, the temperature generally rests at an average low of 65.3°F (18.5°C).

Heat index

In August, the heat index is calculated to be a very hot 95°F (35°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.
Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

The average relative humidity in August is 77%.
