The Winter Season in the UAE: What to Expect

Introduction to UAE Winter

Winter officially commenced in the UAE on December 22, marking a time for cooler temperatures and various weather patterns. According to the National Centre of Meteorology (NCM), the season promises cold nights, mild days, and intermittent rainfall across the country.

Understanding Weather Patterns

Impact of the Siberian High-Pressure System

The winter weather in the UAE is primarily influenced by the Siberian high-pressure system. This system pushes cold air toward the Arabian Gulf through northwesterly and sometimes northeasterly winds. As a result, temperatures can significantly drop, especially during the night and early morning hours, with some inland and mountainous areas experiencing lows below 0°C.

The Role of Low-Pressure Systems

Low-pressure systems from the Red Sea and Mediterranean, along with occasional influences from the east, can lead to increased cloud cover and rainfall. Fog may form during calm and humid early mornings, adding to the winter atmosphere.

Regional Differences Across the UAE

Varied Winter Conditions

The diverse landscape of the UAE results in different winter experiences:

• Deserts: Expect cool nights and early mornings, with pleasantly mild daytime temperatures.
• Mountains: Regions like Jebel Jais and other highlands remain cool, with the coldest temperature recorded so far at 3.5°C on December 20.
• Coastal Areas: Generally feature moderate temperatures, calm seas, and wave heights of 1–2 feet, perfect for marine activities.

Caution During Rainfall

Occasional heavy rain may lead to runoff in valleys and wadis, prompting authorities to advise caution for residents and visitors.
