One of the more reliable months for dry weather before the wetter season starts to return. A good balance of pleasant weather and low visitor numbers.

Aiwo, Denigomodu
September often marks the mellow end of the trade-wind run; while still dry, evenings begin to feel a touch more humid as the region edges toward the wetter season. Short afternoon showers can return occasionally, so plan snorkeling or beach days earlier in the day. The pace in town remains low - excellent for a quiet visit - and packing lightweight, breathable clothing with a small umbrella is a practical choice.
rocky interior
September begins a slow uptick in humidity, although the central interior remains drier than the coastal fringe for longer into the year. Early morning visits continue to be pleasant and dust is moderate, but be prepared for a small chance of afternoon squalls as the wet season approaches. Carry a light raincoat in your daypack and protect electronics from sudden showers and fine dust.
Meneng, Anibare
September’s humidity begins to creep back in though Anibare stays drier than the island’s windward face; occasional clouds appear, but many beach days remain pleasant. Snorkeling still benefits from lower runoff, and the long sandy stretches are comfortable for exercise or quiet reading. Carry a small umbrella for brief showers and time water activities for the morning for the most reliable conditions.
Anabar, Ijuw, Nibok
September sees the first hints of returning humidity, though the north still avoids the worst of the wet season until later; occasional showers become more likely in afternoons. Anabar Lagoon remains a fine morning destination for birdlife and quiet walks, but keep flexible plans for midday when clouds can gather. Bring a small umbrella and expect softer soil in places after sporadic rain.
There are no major festivals or events in Nauru during September to be aware of.
