Although Oman is smaller in area than Germany, for example, the country can be divided into four climatic zones based on its geography. These zones consist of the coastal region in the north (Muscat, Sur, Batina Plain, Sohar), the Hajar Mountains, the interior (desert area) and the southern coastal region consisting of the province of Dhofar.
The climate in the north is characterized by little precipitation and only slight temperature fluctuations between day and night. In summer, the average daily highs are between 35 °C and 40 °C, and in winter they are a pleasant 22-25 °C. You can swim in the sea all year round at temperatures between 24 °C (winter) and 31 °C (summer).
In the mountains, with peaks around 3,000 meters, there are warm summers and cool winters. In the winter months, sub-zero temperatures can be expected regularly at night in the higher mountain areas. In summer, temperatures rise to an average of 30 °C during the day, but at night it always cools down considerably. Warm clothing is always necessary in the Hajar Mountains.
The interior of Oman is largely desert. Here you will also find the deserts Ramlat al Wahiba (Wahiba Sands) and the Rub al-Khali (Empty Quarter). Temperatures are pleasant in winter at 25°C to 30°C, but in summer the thermometer often climbs to an unbearable 50°C or more. These are the peak temperatures in Oman. At night, as in all desert areas, temperatures drop very sharply and it can get really chilly in winter.
The Southern Province of Dhofar (Salalah) has a tropical climate all year round. It is warm and humid. Temperatures range between 20 °C and 30 °C . Between June and September the region is swept by monsoons. During this period there is dense fog and drizzle and the temperature is around 25 °C . This makes the whole province green. This is the so-called “Khareef Season” which is very popular with visitors from the Arabian Peninsula. During the monsoon season, it is not possible to swim in the sea in the south of Oman because of the strong currents that prevail then.
The best time for a beach vacation in Oman is from October to March. The daytime temperatures are comfortable, the water is pleasantly warm and at night it cools down to acceptable temperatures. Basically, Oman can be visited all year round. From April to September, however, temperatures often reach more than 40 degrees Celsius and do not usually drop below the 30 degree mark at night. For a hiking vacation, however, the summer months are ideal. At night, temperatures drop extremely, but they are not at the freezing point, as in the winter months. Those who want to see an extraordinary natural experience that attracts Omani and other Gulf States residents should travel to the southern coast of Oman from June to September. The increased rainfall awakens the vegetation and everything shines in lush green. In addition, every year from July 15 to August 31, the Salalah Tourism Festival takes place, which has an incredibly beautiful and exciting program.
