From January to April, it is hotter, and there are some sunny days; the rains are irregular, and there are long periods without rain, however, in El Niño years, the rains become much more frequent.
The city is located in the west of Ecuador, at 1 degree south latitude, on the coast of the Pacific Ocean, in the province of Manabí. The provincial capital, Portoviejo, is located 25 km (15 miles) to the southeast.
The climate is arid due to the Humboldt Current, a cool sea current from Chile that lowers both the air and the ocean temperature by a few degrees. On the other hand, as mentioned, even in the dry period, mists and cloud banks often form, which reduce the amount of sunshine.
