Weather in July
Temperature
In Naples, the highest average temperatures are observed in July, with a high of 84°F (28.9°C) and a low of 66.7°F (19.3°C).Heat index
The heat index value for July is appraised at a fiery hot 95°F (35°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for 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.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Persist with precautions and heed sun safety advice. Prevention of sunburn is compulsory. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
