July weather forecast
Gammarth, Tunisia

Gammarth's weather during July keeps the summer vibe alive with temperatures peaking at 32.1°C (89.8°F). The city is notable for its higher daylight hours, reduced cloudiness, and the lowest rainfall levels of the year. Despite less wind flow, the ambient pressure remains nearly constant, ensuring a fixed weather routine. Comparatively, July offers a drier, hotter climate than June, urging the residents to adapt to full-blown summer conditions. Albeit being the peak summer month, the weather retains a certain tranquility, ensuring a comfortable lifestyle amid higher temperatures.

Temperature

With the onset of July, Gammarth's average high-temperature experiences a slight rise, moving from June's warm 28.5°C (83.3°F) to a tropical 32.1°C (89.8°F). Gammarth, in July, experiences an average temperature of 23.8°C (74.8°F) at night.

Heat index

The heat index value during July is computed to be a torrid 35°C (95°F). Undertake extra safety actions, heat cramps and heat exhaustion are expected. Heatstroke may result from lengthy activity.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Humidity

With an average relative humidity of 53%, July is the least humid month.

Rainfall

July is the month with the least rainfall. Rain falls for 2.6 days and accumulates 5mm (0.2") of precipitation.

Sea temperature

Note: Individual preferences to cold, influenced by conditions such as sunshine, wind, and surrounding temperature, play a part in the comfort of swimming in 24°C (75.2°F) waters. (As an aside, Olympic swimming standards dictate water temperatures from 25°C (77°F) to 28°C (82.4°F).)

Daylight

The average length of the day in July is 14h and 25min.
On the first day of the month, sunrise is at 05:03 and sunset at 19:42. On the last day of July, sunrise is at 05:23 and sunset at 19:26 CET.

Sunshine

In Gammarth, the average sunshine in July is 12.1h.

UV index

June through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for the ordinary person.
Note: The maximum UV index of 7 during July translates into these guidelines:
Embrace precautions and observe sun safety norms. Evasion of sunburn is a necessity. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes. Caution! Sand and water surfaces escalate the UV intensity from the Sun.
