Saudi Arabia - The climate in short
In Saudi Arabia, there is generally a desert climate, with a long, very hot summer. The rains are very scarce and are usually concentrated from November to April. However, in the southwest, there is a mountainous area that receives some rain from June to September.
The climate in detail
The coasts
Along both the western and eastern coasts of Saudi Arabia, the climate is desert, and it's particularly mild in winter, even warm in the central and southern part of the Red Sea coast, while in summer, it's very hot everywhere, but it's sultry on the shores of the Red Sea, and a bit drier, and therefore torrid, on the shores of the Persian Gulf.
Red Sea Coast
On the
coast of the Red Sea (called
Tihamah), the average temperature in January is around 14 °C (57 °F) in the northernmost part, ie on the Gulf of Aqaba, where it can sometimes get cold at night, while it reaches 25 °C (77 °F) of the southern part, where therefore there's no real winter, and it's hot all year round. Summer is very hot everywhere.

Jeddah
Jeddah, where is located
Already in
Jeddah, in the central part of the west coast, the average in January is 23.5 °C (74.5 °F). Summer is very hot and humid, with highs around 38/39 °C (100/102 °F) between June and August; the heat is sweltering because of the humidity coming from the sea. By contrast, in the days when the wind blows from the interior, the temperature can reach as high as 47/49 °C (117/120 °F) from May to September. Rainfall is definitely scarce: the rainiest month is November, with only 20 millimeters (0.8 inches) of rain. Here are the average temperatures.

Jeddah is a very sunny city, but in summer, it can be reached by some cloud banks. However, this phenomenon is more evident in the southern part of the Red Sea coast, which from June to September is affected by cloud banks coming from Africa due to the southwest monsoon (see below), which on the mountains can also bring some rains.

Mecca
Mecca, where is located
Mecca is not right on the coast, but it lies at sea level and to the west of the mountains, so it's hot throughout the year as well, actually, it's even hotter than Jeddah, especially in summer, when highs are normally around 43/44 °C (109/111 °F).
The humidity is lower than on the coast, but the combination of humidity and temperature makes the heat oppressive. Mecca is a
very hot city, in fact, during the day the temperature normally exceeds 40 °C (104 °F) for several months, from May to September; there are about 300 days with more than 32 °C (90 °F) per year, and the daily average temperature of the whole year is as high as 31.8 °C (89.2 °F). The highest record is 51.4 °C (124.5 °F), set in June 2012. Mecca is therefore one of the hottest large cities in the world. Here are the average temperatures.

Jizan
Jizan, where is located
In
Jizan (or Gizan), in the southernmost part of the coast, winter is even warmer, while summer is a bit less hot because of the south-west winds that in this season blow in a more evident way. Average highs in the summer months are around 38 °C (100 °F); on the other hand, high humidity makes the heat sweltering. Here are the average temperatures.

In the east, on the
coast of the Persian Gulf, the climate is sunny and desert. Winter is mild, but it's cooler than on the Red Sea coast: the average in January is between 12 and 17 °C (54 and 63 °F); sometimes at night it can get cold, especially in the northern part, near the border with Kuwait, where lows can drop to around freezing (0 °C or 32 °F).
Summer is very hot and sunny. However, since the prevailing wind blows from the northwest, originally from the Iraqi desert, and therefore it does not come directly from the sea, the summer is a bit less humid than on the coast of the Red Sea.

In the northernmost part, near the border with Kuwait, the sea in winter is a bit colder, in fact, the temperature drops to 18 °C (64 °F) in February and March. In contrast, in the southernmost part, in the small coastal stretch between Qatar and the Emirates, the sea in winter is a bit warmer, so much so that the water temperature does not go below 23 °C (73 °F).
The syrian Desert
In the far north, there is an offshoot of the Syrian desert, which has a desert continental climate, with relatively cold winters, also due to the higher altitude, and hot summers.
Turaif
Turaif, where is located
In
Turaif, at 850 meters (2,800 ft) above sea level, the monthly average temperature ranges from 7.5 °C (45.5 °F) in January to 29.5 °C (85 °F) in August, with highs around 38 °C (100 °F). During winter, cold waves can occur: in these cases, the temperature can drop to -6/-8 °C (17/21 °F), and more rarely (given the low precipitation amount) it can even snow. On the contrary, despite the altitude, the temperature in summer can reach 43/45 °C (109/113 °F). Here are the average temperatures.

The plateau
Most of the Arabian Peninsula is occupied by a
plateau, called
Najd, whose altitude goes between 400 and 1,200 meters (1,300 and 4,000 feet). In addition to the rocky deserts, there is a series of sandy deserts connected to one another, called
An Nafud,
ad-Dahna, and
Rub 'al Khali; the latter is the southernmost and largest, a huge expanse of sand. The plateau, desert and sunny like almost all of Saudi Arabia, has a fairly uniform climate: mild in winter, but with very cool or cold nights, and very hot in summer, but with low humidity. The main differences occur in winter, when the northern part is much colder than the southern one.

Rub' al Khali
In the south, the desert of
Rub 'al Khali, uninhabited and mysterious, is quite warm even in winter, with highs in January around 25/26 °C (77/79 °F). At night, it can get pretty cool, but temperatures do not drop below freezing. In summer, the southernmost part of this desert is brushed by the south-west monsoon; in fact, some cloud banks may pass over the area, and sometimes, even a rain shower may occur.
Very rarely, the Rub 'al Khali desert may be affected by the remains of
tropical cyclones coming from the Arabian Sea, which can bring sand storms, and unusual rains in the middle of the desert, as happened in May 2018 with Cyclone Mekunu. Cyclones form from May to December, and are more frequent at the beginning of the period (May-June) and a little less at the end (October-December).
In Saudi Arabia, there are practically no rivers of any importance, but as happens in desert countries, there are many dry riverbeds, called
wadis, which can sometimes turn into ephemeral streams after the rains, which are usually short but violent.
The mountains
The western part of Saudi Arabia, known as
Hejaz, is crossed by a mountain range parallel to the coast of the Red Sea. In the north (the area circled in green on the map), the climate is desert, with no summer rainfall, though some rains are possible in winter, and even snowfalls at the highest altitudes, as happens in
Jebel al Lawz, 2,580 meters (8,465 feet) high, located in the north-west.
In the southern part of the mountains, in the Asir, Jizan and Al-Bahah regions (burgundy area), there are several peaks above 2,000 meters (6,500 feet), among which is the highest mountain of Saudi Arabia,
Jabal Sawda, 2,990 meters (9,810 feet) high. In this area, the climate is obviously tempered by altitude, in addition, in summer, especially in the southern part, it is affected by the
southwest monsoon, a wet current affecting southern Arabia, which brings a bit of rain from June to September, as well as widespread cloudiness. Some rain may fall also in spring, between March and May. In some areas, precipitation exceeds 250 mm (10 in) per year, so the climate is semi-arid rather than desert. On the southwest-facing slopes, there are verdant landscapes and terraces, where water springs are used for irrigation.
Abha
Abha, where is located
In Abha, located in the Asir National Park, at 2,000 meters (6,500 feet) above sea level, the average temperature ranges from 14 °C (57 °F) in January to 24.5 °C (76 °F) in July. Here are the average temperatures.

When to go
In much of Saudi Arabia, either in the areas where the winter is mild (ie the northern part of the Red Sea coast, the central plateau, where Riyadh and Medina are located, and the coast of the Persian Gulf) or where the winter is warmer (ie Mecca, Jeddah, the south-central part of the Red Sea Coast and the Rub 'al Khali), the best time is
from December to February, since in this way you can avoid the heat, which can be intense in the rest of the year (but especially in summer).
However, in the northern areas, north of Riyadh (see Ha'il, Rafha, Tabuk) you can avoid the winter, which can be cold, and choose the months of
March and November. In the far north, in the Syrian desert (see Turayf, Al Qurayyat) where the winter is longer, you can choose April and October.
For
swimming and sunbathing, the best month in the Persian Gulf is November (in March the sea is still a bit cool, while in April it starts to get hot). In the central-northern part of the Red Sea you can go in March and November, while in the central-southern part, from Jeddah down to the border with Yemen, you can go from November to March, because in those parts both the sea and the weather are warm even in winter.
In summer, even though the sea is very warm, it's too hot for sunbathing.
What to pack
In
winter: in the Syrian desert, bring warm clothes, such as a down jacket, a hat, a raincoat or umbrella, and a scarf.
In the Persian Gulf coast, bring spring/autumn clothes, a T-shirt for warm days, a sweater and a jacket for the central and southern parts (see Dammam, Al Khobar), a heavier jacket and a hat for the northern part (see Khafji), a scarf for the wind, and possibly an umbrella.
For the Red Sea coast, north of Jeddah, light clothes for the day, a sweater and a light jacket for the evening, which sometimes can also be used in Jeddah and Mecca. In the southern part (see Jizan), in addition to light clothes, you just need a scarf for the breeze and possibly a light sweatshirt for the evening.
For the plateau, Riyadh and Medina, spring/autumn clothes, a warm jacket and a hat for the evening, especially in the north. For the Rub 'al Khali, light clothes for the day, a scarf or turban, desert boots or sandals, and a sweater or jacket for the evening and early morning.
For the western mountains, in the north, warm clothes, such as a down jacket and sweater; in the south, spring/autumn clothes (light for the day), a sun hat, a sweater and a jacket for the evening.
In
summer: for the Syrian desert and the plateau above 700 meters (2,300 feet, see Ha'il), bring light clothes, a sun hat, a sweatshirt or sweater for outdoor evenings, and a scarf.
For Mecca, the plateau and Riyadh, the Rub 'al Khali and the coasts of the Persian Gulf and the Red Sea, lightweight clothes, long and made of natural fabric (cotton or linen), a desert turban; a sweatshirt and a scarf for air conditioned places.
For the western mountains, light clothes for the day, a sun hat or desert turban, a sweatshirt or sweater for the evening, hiking shoes; for the southern part, you can add a raincoat or umbrella.
Women should cover their entire body except for their face and hands.
