Average temperature across Nauru in December.
Aiwo, Denigomodu
Heavy squalls and very humid air characterize the west coast in December, with the odd stormy day knocking around power or small-boat schedules. Yaren fills with locals preparing for holiday events, and while tourist numbers stay tiny, visitor logistics like flights and charters can be affected by weather delays. Pack for heat and sudden rain, keep flexible plans, and expect sticky nights that call for lightweight sleepwear and insect protection.
rocky interior
December keeps the interior in the muggy, wet pattern with frequent brief but heavy showers; the plateau feels hotter after a rain as humidity climbs and evaporation begins. The central area is least hospitable in this month for long outdoor activity - seek shaded coastal areas instead if possible. If you do visit the interior, plan for rapid weather changes, protect camera gear from both water and dust, and limit exposure to midday heat.
Meneng, Anibare
December’s humidity on the southeast coast is high and the occasional prolonged downpour can leave sandy areas compacted and less inviting for sunbathers. Anibare remains accessible but sea conditions can be rough, so stay informed through local contacts before heading out by water. Pack for heat and rain, keep electronics protected, and expect fewer quiet sunrise swims as mornings can still be cloudy.
Anabar, Ijuw, Nibok
December remains wet and humid up north with occasional long rain spells that fill the lagoon and make shoreline walking messy for a day or two. The rhythm of village life continues under the rains, but tourists should expect fewer reliably dry windows for extended outdoor activities. Pack for sudden downpours, prioritize sheltered morning visits, and plan flexible transport since small boats may reduce operations in rough seas.
There are no major festivals or events in Nauru during December to be aware of.
