Weather in August
Temperature
Stilwell's weather in August, with an average high-temperature of a still tropical 89.6°F (32°C), subtly shifts from July's 91°F (32.8°C). Stilwell encounters an average low-temperature of 68.5°F (20.3°C) during August nights.Heat index
August's heat index is estimated at an extremely hot 104°F (40°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
