Jebel Jais is spectacular year-round. During summer (June-September), the summit is up to 10°C cooler than Dubai, making it a perfect escape from the heat. Winter months (November-March) offer the most dramatic weather—temperatures can drop near freezing, and you may even witness rare frost! For the zipline and outdoor activities, spring and autumn provide ideal conditions. We recommend starting early (7-8 AM pickup) to maximize your time and catch the best light for photography.
