Weather in August
Temperature
Littleton marks the onset of August with an average high-temperature of a still moderately hot 80.6°F (27°C), subtly divergent from July's 82.2°F (27.9°C). During August nights, Littleton records an average temperature of 61.5°F (16.4°C).Heat index
For August, the heat index is estimated at 84.2°F (29°C). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.Note that heat index values are valued for light wind and location in the shade. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', comes about by integrating the temperature readings with the humidity levels. 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. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
