Kiritimati raised atoll, and although it does occasionally receive plenty of precipitation, little is retained given the porous carbonatic rock, the thin soil, and the absence of dense vegetation cover on much of the island, while evaporation is constantly high. Consequently, Kiritimati is one of the rather few places close to the Equator which have an effectively arid climate. The temperature is constantly between 24 °C and 30 °C (75 °F and 86 °F) with more diurnal temperature variation than seasonal variation. Easterly trade winds predominate. The flora and the fauna consist of taxa adapted to drought. Terrestrial fauna is scant;
