Map - Nauru

In Nauru the climate is equatorial, hot and humid throughout the year, with constant rains, and without a dry season. No coincidence that this small island is located at the Equator. We can still distinguish a rainier period from December to April, when more than 6 inches per month fall, with a maximum 10 inches per month or more from December to February, and a less rainy period from May to November, when, however, still from 4 to 6 in of rain per month fall. Precipitation amounts to around 80 inches per year. Rainfall can vary from year to year, so that sometimes it can rain a lot even in the least rainy season; however, June is the month that historically has had the lowest rainfall records. The rains occur in the form of showers or thunderstorms, which may be intense, but do not last long, so that the sun has always a chance to shine.
Here is the average precipitation.

The average temperature is extremely stable during the year: lows hover around 75/77 °F, and highs are around 86 °F. There is just a slight rise in temperatures between October and December. Sometimes, however, the temperature can reach 95 °F from November to April.

Nauru is outside the path of tropical cyclones, because at the Equator there's no Coriolis effect, which is necessary to give life to cyclonic vortices.


The sea in Nauru is pleasantly warm all year round, and has a very stable temperature, as we can see in the following table.

When to go

The best time to visit Nauru runs from May to November, being the driest, or rather the least rainy, because showers and thunderstorms may occur even in this period. The period from May to August is still better, because it is slightly less sultry. Not being affected by tropical cyclones, Nauru can still be visited throughout the year. Anyway, the worst period runs from December to February, being the rainiest.
The natural environment of Nauru is still suffering because of the intense mining of phosphates made in the past, and the island is not well equipped for tourism; however, as we have seen the sea is pleasantly warm all year round for swimming and diving.

What to pack

All year round, tropics-friendly, loose fitting clothing, sun hat, a scarf for the breeze, a light sweatshirt for the evening, light raincoat or umbrella.
