January is the coolest month of the UAE year. Daytime highs settle around 24°C, nights drop into the middle teens, and what rain the country receives falls mostly in this part of the calendar. Sunrise in Dubai comes a few minutes after 7 am and sunset before 5:45 pm at the start of January 2029, which is the shortest working daylight of the twelve months and still longer than a London afternoon in the same week.
January opens the first quarter of 2029 on Gulf Standard Time, UTC+4, which the UAE keeps every day of the year without a clock change of any kind. Through January that places the country four hours ahead of London, three ahead of continental Europe and an hour and a half behind India, which sits on the half-hour offset of UTC+5:30 — the reason a call to Mumbai never lands on a round hour.
The turn from January into February takes the country deeper into the only stretch of the year in which a walk at midday is an ordinary thing to do. January 2029 hands over the last of the festival season to a month with no fixed holiday, shortened working hours in every year of this decade, and the first sign of the warmth returning at its far end.
