The climate of Riohacha is
tropical arid. Temperatures are high all year round, but especially from June to August. However, the northeast trade winds blow all year round, tempering the heat. There are two rainy periods, one in May, and the other from August to November, when it is also the period of hurricanes.
The city is located in northern Colombia, on the coast of the Caribbean Sea, in the department of La Guajira, at 11 degrees north latitude. We are in the southern part of the Guajira Peninsula, the driest area of Colombia, where rainfall even drops below 300 millimeters (12 inches) per year.
Riohacha lies at the edge of the area over which
hurricanes, the tropical cyclones of the Atlantic Ocean, can pass. This means that hurricanes affect this area quite rarely, but sometimes they can do it, as happened with Hurricane Joan in October 1988, Cesar in late July 1996, Matthew in late September 2016, and Iota in mid-November 2020. The hurricane season runs from June to November, but they are most likely from August to October.
Best Time
The best time to visit Riohacha is from December to March, as it is the driest of the year. In summer, from June to August, the rains are rare, but the temperatures are even higher than in winter.
