Weather in August
Temperature
August's weather records an average high-temperature of a still hot 89.8°F (32.1°C), showing little deviation from July. Dermott's nights in August cool down to an average low-temperature of 72.1°F (22.3°C).Heat index
For most parts of August, the heat index is computed to be an extremely hot 109.4°F (43°C). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.Keep in mind the heat index values are meant for areas in shade and with light wind. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. 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 highly critical for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Persist with precautions and heed sun safety advice. Prevention of sunburn is compulsory. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
