Weather Conditions and What to Expect

Temperature Variations

In Amman, temperature variations reflect the diversity of its seasons and are markedly influenced by its geographical position. Nestled in the highlands, the city experiences cooler temperatures compared to the Jordan Valley and the desert regions of the country. Winter months, from December to February, bring chilly weather with average temperatures ranging from 4°C (39°F) at night to 12°C (54°F) during the day. Although snowfall is rare, it can occasionally blanket the city, creating picturesque landscapes.

As spring emerges in March and extends to May, temperatures begin to rise, offering a comfortable range of 10°C (50°F) to 25°C (77°F). This period is marked by gradual warming, making it an ideal time for outdoor activities and exploration.

Summer months, from June to August, introduce a sharp increase in temperature. With highs often soaring above 30°C (86°F) and occasionally crossing 40°C (104°F) during heatwaves, the climate remains arid. These hot temperatures encourage reliance on air conditioning and influence daily routines, pushing activities to early mornings or late evenings.

The autumn season, spanning September to November, signifies a welcome respite from the heat. Temperatures begin to drop, settling between 15°C (59°F) and 28°C (82°F). This transitional period is known for its pleasant and moderate climate, providing a balanced atmosphere for both residents and visitors.

Overall, Amman’s temperature patterns are distinct and diversified, with shifts that cater to diverse lifestyle preferences throughout the year.

Precipitation Patterns

Amman’s precipitation pattern revolves predominantly around its winter and spring months. On average, the city receives approximately 270 mm (10.6 inches) of rainfall annually. The majority of this rainfall occurs between November and March, with December and January being the wettest months. During this time, the city can experience rain showers that sometimes lead to temporary flooding due to the arid terrain’s limited absorption capacity.

Rainfall events are typically short-lived, yet they contribute significantly to the annual totals. Spring sees a reduction in precipitation as the season progresses, gradually giving way to dry, clear skies heralded by the onset of summer.

From June through September, rainfall is sporadic and minimal, with some months recording no precipitation at all. The dry conditions of the summers emphasize the reliance on water conservation strategies within the city.

Autumn witnesses the gradual return of precipitation marks, preparing the environment for another cycle of wet weather in the approaching winter. Understanding Amman’s precipitation pattern enables residents and visitors to plan activities around anticipated rainy days, ensuring optimal enjoyment of the city’s offerings.

Wind and Sandstorms

Wind phenomena in Amman vary considerably, with notable impacts on the city’s climate and daily life. The city experiences two primary types of wind: the Khamsin winds and the cool breezes from the Mediterranean. The Khamsin, a hot, dry wind originating from the desert, typically occurs in late spring and early autumn, bringing with it dust and sandstorms. These winds can dramatically reduce visibility and increase air pollution levels, causing interruptions to transportation and outdoor activities.

In contrast, the cooler Mediterranean breezes, particularly prevalent in spring and early summer, can provide relief from the intense heat and improve comfort levels in the city. These winds, blowing from the west, often help moderate temperatures and clear dust from the air, enhancing the overall quality of the atmospheric conditions.

Annual patterns indicate that sandstorms are more common during transitional seasons when temperature fluctuations are significant. Residents often stay indoors during peak wind and dust events, while those venturing out are advised to wear protective masks and eyewear to shield themselves from airborne particles.

Sunshine and UV Index

Amman boasts an impressive amount of sunshine throughout the year, averaging about 310 sunny days annually. The ample sunshine is a hallmark of the city’s climate, contributing to various outdoor activities and enhancing its appeal as a tourist destination.

Given the city’s predominantly clear skies and high altitude, the UV index can reach levels classified as high or very high, particularly during the summer months. With UV index values often exceeding 8 on a scale of 1 to 11+, it is imperative for residents and visitors to take necessary precautions.

This includes applying broad-spectrum sunscreen, wearing protective clothing, hats, and sunglasses, and avoiding prolonged exposure to direct sunlight during peak hours. Understanding the implications of the UV index helps mitigate health risks such as skin damage and heat-related illnesses.

Despite the challenges posed by high UV levels, the abundance of sunshine also enables sustainable practices like solar energy utilization, contributing positively to the city’s environmental landscape.
