This study addresses rainfall trends, the frequency of droughts, La Niña influences and the relationship between rainfall and Sea Surface Temperature (SST) in Tuvalu. The findings revealed that;

* de-trended rainfall time series show declining trends in all four rainfall stations over the period 1953-2012;

* the frequency of drought ranges from three to fourteen years with a mean of nine years

* the occurrence of drought appears to follow the La Niña years

* boplots provide an effective option for defining drought

* there is empirical support for a moderate to strong correlation between the de-trended values of SST and rainfall in the area of study
