Weather in August
Temperature
At the onset of August, Calera records an average high-temperature of a still tropical 90.1°F (32.3°C), showing little deviation from the preceding month. In the month of August, the temperature generally rests at an average low of 71.2°F (21.8°C).Heat index
August's heat index is estimated at a scorching 109.4°F (43°C). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Take precautions against overexposure. Protection against sun damage is needed. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
