Weather in August

August, the last month of the summer in Saint Stephen, is another tropical month, with an average temperature fluctuating between 72.7°F (22.6°C) and 89.2°F (31.8°C).

Temperature

August commences with an average high-temperature of a still tropical 89.2°F (31.8°C), showing little deviation from July's 90.3°F (32.4°C). August nights are marked by an average low-temperature of 72.7°F (22.6°C).

Heat index

During August, the heat index is computed to be an extremely hot 109.4°F (43°C). Alert: Heat cramps and heat exhaustion are likely to occur. Prolonged exertion can lead to heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
