Temperature
Entering July in Poros, the average high-temperature is recorded at a still warm 29.3°C (84.7°F), exhibiting a minimal shift from June's 26.8°C (80.2°F). Poros records a consistent low-temperature of 23.7°C (74.7°F) during July nights.Heat index
For most parts of July, the heat index is computed to be a hot 31°C (87.8°F). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
