South Tarawa experiences a tropical wet and dry climate with consistently warm temperatures year-round, hovering between 26°C and 32°C with little variation.

The wet season brings heavy downpours and high humidity, making quick-dry fabrics essential as clothes can remain damp for hours in the thick air.

Temperatures rarely drop below 25°C even at night, so thermal layers are entirely unnecessary regardless of when you visit.

Trade winds provide some relief during the drier months, though humidity remains high throughout the year at around 80 percent.

The intense equatorial sun and reflective lagoon waters make sun protection doubly important, as UV rays hit from both above and below.
