The coldest phase of the winter season in the UAE and across the wider Gulf region is expected between January 10 and January 22, according to astronomer Ibrahim Al Jarwan, Chairman of the Emirates Astronomical Society.
The temperature drop corresponds with “Der Al Sittin,” a period deeply rooted in Gulf folklore and long associated with biting cold conditions. Al Jarwan said early morning temperatures during this phase could dip below 5°C, particularly in inland and desert areas.
This seasonal chill also coincides with the evening culmination of the Thuraya (Pleiades) constellation, a celestial marker historically linked with severe winter cold in Arab astronomical traditions.
Adding to the astronomical significance, Al Jarwan noted that the first full moon of 2026 — commonly known as the Wolf Moon — occurred when the Moon was at perigee, creating a visually striking supermoon. The term “Wolf Moon” stems from European and North American folklore, referencing wolves howling during harsh winter conditions.
Rainfall levels in January typically average between 12 and 18 millimetres across the UAE, spread over six to eight days, though no major low-pressure weather systems are currently expected in the short term.
Al Jarwan stressed that long-range weather forecasts remain uncertain due to the atmosphere’s complex behaviour. Forecast accuracy, he explained, exceeds 90 per cent only within two days of a predicted event, dropping significantly beyond ten days.
Despite forecasting limitations, residents are advised to prepare for colder mornings during this period, particularly in open and desert areas.
