Weather in August
Temperature
At the start of August, Stella's average high-temperature reaches a still hot 87.6°F (30.9°C), subtly different from the preceding month. Throughout August nights, Stella registers an average low-temperature of 67.3°F (19.6°C).Heat index
Throughout August, the heat index is evaluated at a fiery hot 100.4°F (38°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. 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 particularly important for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
