Weather in August

August, the last month of the summer in Iron City, is another hot month, with an average temperature fluctuating between 87.6°F (30.9°C) and 68.5°F (20.3°C).

Iron City starts August with an average high-temperature of a still hot 87.6°F (30.9°C), hinting at a minimal fluctuation from July. Throughout the month of August, Iron City witnesses an average low-temperature of 68.5°F (20.3°C).

Heat index

In August, the heat index is computed to be a sweltering 102.2°F (39°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
