Aqaba in October is certainly cooler since the summer season has ended and the winter has finally arrived. This would be a great time to visit the city's mountainous regions because you will not be as badly beleaguered by the blistering hot weather of the summer months. Instead, you will be welcomed by the cool and slightly chilly weather a perfect balance to an activity that can be physically demanding.
October weather in this sprawling city has an average high temperature of 32.7°C or 90.9°F. This is commonly experienced in the afternoon when the sun is high. The average low temperature is at 19.9°C or 67.8°F, so expect to endure colder evenings during your stay.
Since the temperature can still exceed 30°C, it is best that you bring summer clothes, preferably made of cotton so you can be more comfortable in moving around the city. However, don't forget to pack up some light jackets or sweaters so you will have something to warm you up if the temperature suddenly drops.
Diving is still available to those who are interested but make sure that you start wearing a full suit since the water is colder during this time of the year. The water temperature is about 25°C or 77°F. Don't worry about not having clear visibility underwater because Aqaba has the clearest sea water that you will ever experience.
One of the things that you must take note of during this month is that the locals will celebrate the end of Ramadan or Eid Al-Fitr. It is one of the most joyous celebrations in the Muslim calendar, so expect to see extravagant events and parties in the city.
Amman Marathon will also commence in October. It is a popular marathon that draws a lot of visitors from all over the world to participate, so it is normal, at this time of the year, to see Aqaba teeming with tourists whose luxurious hotels and resorts provide good accommodation and entertainment in between the racing action.
