Water Temperature Oman

The Sultanate of Oman is located in the southeastern part of the Arabian Peninsula, and its coast with a length of 2000 km is bordered by the Indian Ocean, the Gulf of Oman and the Arabian Sea, with the coast being divided into two major sections. Along its long coast, Oman is dominated by the influence of the prevailing trade winds, as well as the Indian monsoons.

The beaches in the north of the country, along the Gulf of Oman, are suitable for bathing year-round. While the water temperature in winter is around 25°C, it rises to a very warm 26°C to 31°C in the summer months. Due to the high water temperatures, it stays warm all year round.

The Arabian Sea along the southern coastline of Oman also invites swimmers all year round. The climate here is primarily tropical and is generally subject to less variation in air and water temperatures. The sea temperature here oscillates between 25°C and 29°C.

In the underwater world along the Omani coasts of the Indian Ocean, you can find whales and dolphins from the northern region Musandam to the southern region of Dhofar. These mammals evolved about 50 million years ago in our world's oceans. The biggest challenge for these animals was to adapt breathing to life in water. Nature solved this problem by developing nostrils into what are called blowholes on the top of the head. Movement was optimized by their streamlined bodies. The tail fin and dorsal fin developed for navigation. The fur needed on land was no longer necessary and was replaced by ...

Oman had around 4.52 million inhabitants in 2021. It is likely that the number has again increased, as it has generally been on the rise in recent decades. The birth rate of almost three children per woman not only reflects the Arabian love for large families, rather, it is an expression of the deep satisfaction that persists in the country and of the fact that people have experienced a transformation in the last few decades that is second to none. Due to this fact, more than half of Omanis are under 18 years old and more than 30 % are under 15. The people of Oman today have a much longer life...
