August brings a pause to the increasing warmth, with a subtle dip in temperatures. Aberdeen sees a slight dip in humidity relative to July. Even though daylight hours begin to wane, there is still ample sunshine. Rainfall is sparser, creating a balance of sunshine and cool winds. August's weather is a perfect blend of summer's warmth and the approaching autumn's mildness.

Heat index

The heat index value for August is appraised at a tropical 86°F (30°C). If exposure and activity are sustained, they might cause a feeling of weariness, resulting in heat cramps.

Note: The heat index, also known as 'felt air temperature' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity.

It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
