Demand peaks. Hotel rates sit at their yearly high, lifted further by the Christmas and New Year holidays at the beach resorts, so book accommodation, desert camps, and restaurants well ahead.
Note: desert and mountain nights are genuinely cold now — pack warm layers for camping and Jebel Akhdar/Jebel Shams. Carry a headscarf and fully modest clothing for the Grand Mosque, which doesn't lend robes.
