Weather in August
Temperature
During August, Roswell observes a subtle ascent to a still hot 89.4°F (31.9°C) from July's 90.3°F (32.4°C) in the average high-temperature. In the month of August, the nighttime temperature dips to a steady average of 70.3°F (21.3°C).Heat index
During August, the heat index is computed to be a torrid 102.2°F (39°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
Humidity

The month with the most rainfall is August, when the rain falls for 20.3 days and typically aggregates up to 5.55" (141mm) of precipitation.Snowfall

Sunshine
The average sunshine in August is 9.3h.UV index
May through August, with an average maximum UV index of 6, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for the ordinary person.Note: In August, the maximum UV index of 6 translates into these guidelines:
Stay clear of intense sun exposure. Solar protection is of utmost significance. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
