January sits in the heart of the dry season: a handful of short showers all month, glassy water on every beach and the year's lowest humidity. All boat trips run, including the Similans. Book ahead — New Year weeks sell out months in advance and rates are the year's highest; after Jan 10 the same weather costs noticeably less.
