Peak Season
In the Andean Region, the dry season falls between December and March and July and August. Christmas is a particularly festive time in Colombia, though prices often rise and hotel rooms fill up quickly in Cartagena and the Atlantic Coast, as well as in other popular tourist destinations. During the Christmas holiday, Easter, and summer vacation, you'll have to book hotels in advance and be prepared to pay a bit extra. If possible, avoid Colombia in October and November, as these are the rainiest months, and flooding and poor road conditions are common.
Climate
Because of its proximity to the Equator, Colombia's temperature varies according to altitude rather than season. In high altitudes, days are cool and nights can dip near the freezing mark. In lowlands, expect a tropical, humid climate with little difference between daytime and nighttime temperatures. As a general guide, the average temperature in Bogotá is 14°C (57°F), in Cartagena 31°C (87°F), and in Medellín 24°C (75°F).
Public Holidays
Colombia has more public holidays than any other nation except Brazil. Usually, if a holiday falls on a Saturday or Sunday, it is celebrated the following Monday. Public Holidays are New Year's Day (Jan 1); Epiphany (Jan 6); St. Joseph's Day (Mar 19); Maundy Thursday and Good Friday (Mar/Apr); Labor Day (May 1); Ascension (May); Corpus Christi (May/June); Sacred Heart (June); Day of St. Peter and St. Paul (June 29); Independence Day (Aug 7); Assumption (Aug 15); Discovery of America (Oct 12); All Saints' Day (Nov 1); Independence of Cartagena (Nov 11); Immaculate Conception (Dec 8); and Christmas (Dec 25).
