July weather forecast
Cairo, Egypt

Surpassing June, July stands as the warmest month in Cairo. Thermal contrast between the cooler beginning of the year and July is most striking, as July records a scorching mean high temperature of 34.7°C (94.5°F). Despite the relentless heat, the city doesn't entirely enter a period of drought. Tears of the Nile, or freshwater summer rainfall, invigorate Cairo, though this isn't a common occurrence. Humidity surges slightly, tempering the adverse impacts of the high temperatures. Moving forward, August mirrors the July weather conditions.

Temperature

The warmest temperatures occur during July, when averages reach a peak of 34.7°C (94.5°F) and a low of 22°C (71.6°F).

Heat index

For July, the heat index is evaluated at an extremely hot 43°C (109.4°F). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
Keep in mind the heat index values are meant for areas in shade and with light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. 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 remain especially vital for babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.

Humidity

In July, the average relative humidity is 58%.

Rainfall

July through September are months without rainfall.

Daylight

The average length of the day in July is 13h and 52min.
On the first day of the month, sunrise is at 5:57 am and sunset at 8:00 pm. On the last day of July, sunrise is at 6:13 am and sunset at 7:49 pm EEST.

Sunshine

UV index

June and July, with an average maximum UV index of 12, are months with the highest UV index. A UV Index estimate of 11, and higher, represents an ultimate health vulnerability from exposure to the Sun's UV radiation for the ordinary person.
Note: The maximum daily UV index of 12 in July interprets into the following recommendations:
Take all required precautions, as unprotected skin and eyes can burn in minutes. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days. Every two hours, apply and reapply an SPF 30+ broad-spectrum sunscreen, especially after swimming or engaging in outdoor activities.
