The temperature of the ocean water is always warm because Nauru is very close to the equator. The warm temperature makes the sea available for swimming during the whole year. Thanks to its exotic tropical climate, Nauru is home to alluring beaches. The water is very pure in most parts of the sea. Sandy beaches are rare, and coral reefs are along the coastlines most of the time. You can enjoy swimming in the charming Pacific ocean, but you need to be careful during the windy weather conditions. Wind can be very strong in Nauru due to the surrounding Pacific Ocean. If you are fond of relaxing on the beach, you should avoid swimming on windy days during your travel to Nauru island.
