Weather in August
Temperature
In August, Greenock experiences a barely noticeable shift in meteorological conditions, with average high-temperatures moving from 82.9°F (28.3°C) in July to a still warm 81.5°F (27.5°C). An average low-temperature of 60.1°F (15.6°C) is observed during the August nights.Heat index
The heat index value during August is calculated to be a hot 86°F (30°C). One might feel worn out with persistent exposure and activity, resulting in heat cramps.Consider that heat index readings are for situations in the shade and light wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for 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.
