September weather forecast
Gaza, West Bank

Weather in Gaza, West Bank starts to cool somewhat in September. A slight decline in peak temperatures and relative humidity levels marks the transition to the shoulder season. Clear skies persist and daylight hours decrease steadily. Emphasis on moderate temperatures and marginally falling sea temperature contribute to mild weather as September acts as a precursor to the arrival of fall in October.

Temperature

The transition into September marks the average high-temperature at a still tropical 30.6°C (87.1°F), differing minimally from August's 31.7°C (89.1°F). Gaza throughout September, records an average low-temperature of 20.5°C (68.9°F).

Heat index

In September, the heat index is calculated to be a blisteringly hot 42°C (107.6°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Humidity

The average relative humidity in September is 86%.

Rainfall

In Gaza, in September, 3mm (0.12") of precipitation is typically accumulated. During the entire year, Gaza aggregates up to 394mm (15.51") of precipitation.

Note: The maximum daily UV index, 9 in September, converts into the following recommendations:
Always be mindful of protection. The risk of damage to skin and eyes is significant if neglected. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Sun protection is enhanced with clothing that boasts a tight weave yet offers a loose fit. One should apply and reapply liberally a broad-spectrum sunscreen of SPF 30+ every two hours and immediately after a swim or an outdoor exercise. Stay cautious! Sand and water reflections increase UV radiation potency.
