For instance, the city of São Tomé, located on the northeast coast of the island of São Tomé, and the city of Santo Antonio, situated on the smaller island of Príncipe, experience similar weather patterns due to their coastal locations. However, areas at higher altitudes, such as those in the Obo National Park, may experience slightly cooler temperatures.

It's noteworthy that despite the heavy rainfall, life in the islands thrives during this period, with vibrant flora and fauna on full display, making it an appealing time for nature enthusiasts.
