Where is hot in January for a beach holiday?
January beach holidays split into two different plans: mild weather for days outdoors, or tropical water for long swims. The Canary Islands offer the first, while the Maldives and Thailand's Andaman coast are stronger starting points for the second. A sunny terrace in Tenerife does not mean the Atlantic will feel like a tropical lagoon.
Winter sun or warm water?
For a swimming-led trip, compare the Maldives with Railay in Krabi. January falls within the Maldives' usual dry season, although showers remain possible. If restaurants and outings matter as much as beach time, check what is within walking distance of your accommodation and which trips require a boat. Check boat transfers before choosing accommodation: a late flight arrival can affect the first night of an island holiday.
