August, the last month of the summer in Harbour, is another warm month, with an average temperature fluctuating between 61°F (16.1°C) and 85.5°F (29.7°C).

Temperature

The arrival of August denotes a barely perceptible change in the average high-temperatures to a moderately hot 85.5°F (29.7°C) from July's 86°F (30°C). Harbour in August observes a sharp transition from the daytime heat, falling to an average low of 61°F (16.1°C).

Heat index

For most parts of August, the heat index is calculated to be a torrid 95°F (35°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
