Weather in August
Temperature
In August, Littleton experiences a minor shift in meteorological conditions with average high-temperatures marked at a still moderately hot 82.9°F (28.3°C), closely mirroring the climate in July. Throughout August, the temperature tends to fall to a consistent average low of 64.2°F (17.9°C).Heat index
For August, the heat index is estimated at a hot 91.4°F (33°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Consider that heat index readings are for situations in the shade and light wind. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.

Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
