Your January weather guide
Yes, January is a good month for the United Arab Emirates if you want warm days without making intense heat the focus of your trip. Country averages of 24°C by day and 15°C at night favour time outdoors, with a light layer for evenings. The sea averages 22°C, so swimming is possible but may feel cool. Dubai edges ahead for daytime warmth, while Abu Dhabi has slightly milder nights. The catch is that beach weather is not guaranteed.

Dubai is the warmer choice during the day, averaging 24°C against Abu Dhabi's 23°C, but the gap is small enough that it should not decide your whole trip. Dubai also has slightly warmer sea water at 22°C, compared with 21°C in Abu Dhabi, which gives it a modest advantage if swimming matters. Abu Dhabi turns the tables after dark, with nights averaging 16°C rather than Dubai's 14°C. Both average 2 rainy days, so neither has an advantage on that measure. Choose Dubai for the warmer daytime and sea averages, or Abu Dhabi if you put more weight on milder evenings; neither promises hot beach conditions every day.
Pack light daytime clothes, sun protection and a jumper or light jacket rather than treating January as an entirely hot-weather trip. The country averages 7.2 hours of sunshine, giving outdoor plans a useful amount of sun without guaranteeing clear skies throughout your stay. Midday is a sensible time to aim for the beach if you want the warmest-feeling conditions; mornings and evenings call for more flexibility with layers. An average of 2 rainy days makes rain a relatively small concern, not something to rule out. Keep plans adjustable, and favour accommodation with a heated pool if cool sea water would put you off swimming.
A little more detail
Plain answers, grounded in the averages.
Dubai is the warmest of the 2 places we track in United Arab Emirates in January with an average high of 24.0°C; Abu Dhabi is the coolest at 23.2°C.
The sea averages 22°C or more at Dubai (22°C) in January.
The sea averages 22°C in Dubai and 21°C in Abu Dhabi. That can suit a swim, but it is not bath-like warmth. If you are sensitive to cool water, Dubai has a slight edge, though neither destination guarantees comfortable swimming for everyone.
The United Arab Emirates averages 24°C by day, compared with London's 7°C. That is a substantial change for daytime clothing and outdoor plans, but evenings still warrant a layer, with the country averaging 15°C at night.
Yes. In Dubai, the warmest destination in the figures, 36% of January days exceed 25°C. The 24°C daytime average is therefore a useful guide rather than a daily limit. Pack for warmer spells as well as cooler evenings.
