Temperature

Venice reaches its highest average temperatures in July, measuring 27.7°C (81.9°F) at the peak and 18.3°C (64.9°F) at the lowest.

Heat index

July's mean heat index is estimated at a tropical 30°C (86°F). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.
Consider that heat index readings are for situations in the shade and light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.

Take the necessary steps to protect yourself; unprotected skin and eyes are vulnerable to damage. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Outfit yourself in sun-safe attire, like long sleeves, pants, a hat, and UV-blocking sunglasses. Warning! Reflective surfaces like sand and water amplify the Sun's UV radiation.
