Temperature
July and August bring Penteli's highest average temperatures, reaching a high of 30.3°C (86.5°F).Heat index
The heat index in July is evaluated at a tropical 32°C (89.6°F). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.Heat index readings emphasize conditions of light breezes and shaded spots. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a metric representing the sensation of warmth when air temperature and moisture come together. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones regularly neglect the requirement for rest and fluid replenishment.
