Climate Saudi Arabia
JEDDAH AND THE AREA LONG OF THE RED SEA:
In Jeddah and the area along the Red Sea it is generally hot and humid, at night there is hardly any cooling. The cool season in this area usually lasts from December to March. Temperatures range between 21 and 30°C, with night and morning temperatures of 16/17°C in February and around 27°C at noon. From April the hot season starts in this area of Saudi Arabia with high humidity and day temperatures between 25 and 45°C (in August between 31 and 45/47°C). During the summer months the humidity is sometimes over 80 percent. Except in the mountains, rainfall is rare. In the interior of the country (Riyadh) there is a continental desert climate with strong temperature fluctuations between day and night and between summer and winter. Here the summer months are dry with daytime temperatures between 40 and 42°C. Not infrequently in this region of Saudi Arabia 50°C are reached in the shade during the summer. At night it is much cooler, but still above 24°C. The hot climate is bearable as the air is very dry. Precipitation is rare, then however partly very violent. In the winter months from December to February it is usually not warmer during the day than 25°C and at night the temperatures sink to near freezing. In January it can even happen that temperatures drop below freezing point. Occasionally there is rain, sometimes snow showers.
EAST COAST - ARABIC GULF:
On the east coast the summer months are hot with about 40°C and there is a high humidity. Occasionally, however, there are dry Shamal winds from the north. Rainfalls are rare in this area. In the winter months the temperatures are 10-12°C (in the morning) and 18-20°C (at noon). Cold air from the north occasionally leads to temperatures close to freezing. In the months from November to February most of the rain falls.
Climatically the best travel time is from May to September.
