, is a tropical summer month, with an average temperature fluctuating between 30.9°C (87.6°F) and 18.4°C (65.1°F).
An excellent water temperature of 25.3°C (77.5°F) and only 2.3 rainfall days, with 9mm (0.35") of accumulated rainfall, makes July a prime for swimming and other water activities.
In July, the average high-temperature is practically the same as in June
- a hot 30.9°C (87.6°F). In July, in Corfu, the average low-temperature is 18.4°C (65.1°F).
In July, the average heat index is computed to be a sweltering 35°C (95°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Note that heat index values are valued for light wind and location in the shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.Note
: The heat index, also known as 'feels like', 'apparent temperature', '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. This effect is individual, with diverse people perceiving weather differently for numerous reasons (metabolic differences, wind, pregnancy), and activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it is vital to remain hydrated, particularly during prolonged physical activities.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
The least humid month in Corfu is July, with an average relative humidity of 60%.
July is the month with the least rainfall. Rain falls for 2.3 days and accumulates 9mm (0.35") of precipitation.
In Corfu, the average water temperature is 25.3°C (77.5°F).Note
: For swimming, diving, and other water activities, temperatures between 25°C (77°F) and 29°C (84.2°F) are perceived as very enjoyable and pleasurable for prolonged periods without feeling uncomfortable.
In Corfu, the average length of the day in July is 14h and 39min.
On the first day of the month, sunrise is at 06:16 and sunset at 21:11. On the last day of July, sunrise is at 06:38 and sunset at 20:54 EEST.
July has the most sunshine of the year in Corfu, with an average of 11.8h of sunshine.
The months with the highest UV index in Corfu are June and July, with an average maximum UV index of 9. A UV Index reading of 8 to 10 represents a very high health vulnerability from unprotected exposure to Sun's UV rays for the average person.Note
: The average daily UV index of 9 in July transform into the following instructions:
Take special precautions, as unprotected skin can be damaged and can burn quickly. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects. A broad-spectrum sunscreen of SPF 30+ should be liberally applied and re-applied every two hours, and immediately after an outdoor workout or a swim. Beware! The reflection of water and sand dramatically increases exposure to the UV rays.
