I seem to be getting quite a few people on this site coming from Google and who were looking for more information about kitesurfing in Oman. Because of this I thought I will write a bit more information about the spot where people usualy go during the summer monsoon.
The main place is Aseelah, a small fishing village about 4 hours south of Muscat. This area of Oman catches the tail-end of the monsoon season and because of this between the end of May and Septemeber the wind blows almost every day, reaching very often 30 knots and above. The main kitesurfing beach is about 20km north of Aseelah off the road to Ras Al Had. If you are passing on that road in the weekend during the summer months you will most likely see kites in the air. In the mornings the wind is off-shore and quite hot. Around 11-12 every day it turns cross-shore coming from the right and the air gets a lot cooler (the temperature can be 10-15 degrees cooler than Muscat). There is a nice point that picks up swell and most days you will find nice 4-5 foot waves to play with. The beach is very long, so there is plenty of space if you get into trouble. The only problem is that there can be quite a few sharp rocks in the water.
Accomodation wise, there are 2 options… you can brave the wind and camp on the beach or sleep in the Ashkharah Hostel, half an hour away. The beach option can be really nice if the wind doesn’t carry on during the night. But we have had nights camping here when we woke up completely covered in sand blown by the wind. The hostel is a more expensive option, costing about 20 Omani Riyals per night. But you do get a kitchen, tv and a good bed to sleep in after a long day spent kiting.
