Nauru is one of the world's smallest countries, a lone raised-coral island in the western Pacific with a phosphate-mined interior and a single paved road around the coast. The appeal lies in the coral pinnacles inland, the narrow reef and the island's mining history. The equatorial climate stays warm all year, wetter from November to February and drier and breezier from June to September, when travel is easiest.
Warmest month: February (28°C). Wettest: February (143 mm). Best overall score: April (6.3/10).
