dc.description.abstract | The study quantified rainfall variability for March–
May (MAM) and October–December (OND) seasons in
Tharaka district, Kenya. The parameters analysed were interannual
variability of seasonal rainfall, onset and cessation
using daily rainfall data in three agro-ecological zones’
stations. Percentage mean cumulative method was used to
determine onset and cessation, and seasonal variability was
estimated using rainfall variability indices. Although both
seasons are highly variable, OND has been persistently below
mean over time while MAM shows high within-season
variability. Despite the near uniformity in the mean onset
and cessation dates, the former is highly variable on an interannual
scale. The two rainfall seasons are inherently dissimilar
and therefore require specific cropping in agro-ecological
zone LM4 and LM4-5. It is possible that farmers in IL5 are
missing an opportunity by under-utilising MAM rainfall. The
results should be incorporated in implications of climate
variability and vulnerability assessment in semi-arid Tharaka
